Peak iPhone

This will be a very interesting week on the stock market, not least the US mid-terms and the ongoing US/China trade saga, which will likely determine the short-term direction of the market. Apple (AAPL) reported last week and another stellar report was hoped for to calm technology weakness. Instead of a stellar report the market got weak Q1 guidance and the news that AAPL would drop detailed product reporting for their FY2019. Given that there is a massive industry dedicated to examining iPhone trends, the lack of specific numbers being disclosed has caused consternation amongst commentators.

It has been about a year since I last posted on AAPL (here) when it traded around $170. Of course, it has since traded up to a high of $230 before falling back to just above $200 currently. There is no doubt that the smartphone market is saturated with IDC estimating global smartphone shipments falling in Q3 by 6% to 355 million unit. In this environment, it makes sense to me for AAPL to focus on higher value smartphones and to extracting increased fees from services on their installed base. Extrapolating on the iPhone installed base analysis from my last post, I estimate that the iPhone installed base will peak around 650 units based upon iPhone unit sales fall to 200 million and 190 million in FY2019 and FY2020 respectively from 218/217 million in FY2018/2017. The active installed base, excluding non-core users, peaks around 570 million. My projections are shown below.

I have also assumed that the ASP for FY2019 and FY2020 increases to $819 and $847 respectively from $759 in FY2018. I further assumed that service revenue increases as a percentage of total revenue to 18% for FY2020 from 14% in FY2018. I suspect this may be too light given AAPL’s decision to move its reporting focus away from products to services. Although AAPL’s net cash pile is slowly dwindling (approx. $120 billion at end September from $170 billion at the end of December 2017), I think a more focused move by AAPL into the home and content to take on Netflix and Amazon will be a feature of the next few years (bring on the NFLX rumours, again!). My resulting quarterly revenue estimates into FY2020 are shown below.

As you can see, these estimates do show overall revenue moderating with revenue for FY2019 and FY2020 at $270 billion and $273 billion respectively from $266 billion in FY2018. My diluted EPS estimates, assuming the same trend of share buy-backs, for FY2019 and FY2020 are $13.30 and $14.80, representing EPS growth of 12% and 11% respectively. These EPS estimates are consistent with current consensus. At a share price of $200, the forward PE would be 15 and 13.5 for FY2019 and FY2020 respectively.

My usual forward PE excluding cash graph, at an AAPL stock price of $200, is below. If AAPL were to return to its historical average multiple since 2009 of 9, then AAPL’s stock could fall back to $160 or below if the market gets really spooked about peak iPhone.

The question therefore is how the market is going to react to AAPL’s attempt to move the focus from its hardware results and more towards its service business from its massive and loyal installed base. Changing the market’s obsession from iPhone sales will be no easy task. AAPL is an emotive stock, not only because of its products but for its incredible historical value creation. It is the one stock that I have always regretted selling any of. I do not think now is the time to sell AAPL but I will wait for the stock price to settle, particularly in the current volatility, to consider buying more. A fall towards $170 would be too tempting to ignore for this wonderful firm. Mr Buffet and the firm’s own buy-back programme make such a fall unlikely in my view but one can only hope!

Peak Earnings?

With the S&P500 down 9% off its high this month after last week, the question everybody is asking is whether this is a buying opportunity or the beginning of a new phase in the market. I have no idea. Nobody really does. I suspect this week will be bumpy but will rally off Fridays’ lows as there is some cheap names who have been hit hard. I have been modestly dipping my toe in on some names but am waiting before making any big moves. I hope to post on a few of the stocks regularly mentioned in this blog in the coming weeks.

The underlying concerns about the global economy and trade, the impact of US rate increases and quantitative tightening, Italy, to name but a few, have been and continue to be real issues to consider. The fact that the market has turned on a penny and is now all worried about the issues it shrugged off a few weeks ago is, well just how markets are!

What I do know is that this bull market has all been about earnings and margin growth, nothing else matters. So, I took the latest operating EPS and sales estimates for 2019 from S&P, extrapolated them into 2020, assuming a modest slowing of the EPS growth. These operating margin figures and assumed sales figures form the basis of Scenario 1. Stressed operating margin and sales formed the basis for Scenarios 2 and 3, with Scenario 2 falling back to the 2013-17 average operating margin of 9.5% and Scenario 3 falling more severely to the 2008-18 average of 8.75%. The graph below shows the operating margin assumptions in a historical context for each scenario.

Assuming a price for the S&P500 as per Friday’s close of 2,659, the EPS figures with respective trailing and future 12-month PEs are as per the graphs below.

So, if the current operating estimates for 2019 stand up and continue into 2020 as per Scenario 1, then I would say the current dip is a buying opportunity with a forward 2019 and 2020 PE of 15 and 14 respectively. If, however, you feel that we have reached peak earnings and a modest enough EPS retrenchment over 2019 and 2020 is likely as per Scenario 2, then the current S&P500 level looks vulnerable to further downside as the implied forward PEs of 17.5 and 18.7 for 2019 and 2020 look rich in a downward trending EPS environment. If, as per Scenario 3, the EPS retrenchment is more severe, then we are in for a very bumpy ride with another 15% to 25% downside possible.

To state the obvious, the current market focus is all about the earnings outlook for 2019 and 2020. The mid-terms over the next few weeks will be another factor to consider. It will be interesting to see if the market focus moves away from the economic prospects over the next few years and more towards 2018 bonuses and end of year window dressing as this quarter progresses!

Broken Record II

As the S&P500 hit an intraday all-time high yesterday, it’s been nearly 9 months since I posted on the valuation of the S&P500 (here). Since then, I have touched on factors like the reversal of global QE flows by Central Banks (here) and the lax credit terms that may be exposed by tightening monetary conditions (here). Although the traditional pull back after labor day in the US hasn’t been a big feature in recent years, the market feels frothy and a pullback seems plausible. The TINA (There Is No Alternative) trade is looking distinctly tired as the bull market approaches the 3,500-day mark. So now is an opportune time to review some of the arguments on valuations.

Fortune magazine recently had an interesting summary piece on the mounting headwinds in the US which indicate that “the current economic expansion is much nearer its end than its beginning”. Higher interest rates and the uncertainty from the ongoing Trump trade squabble are obvious headwinds that have caused nervous investors to moderate slightly valuation multiples from late last year. The Fortune article points to factors like low unemployment rates and restrictions on immigration pushing up wage costs, rising oil prices, the fleeting nature of Trump’s tax cuts against the long-term impact on federal debt, high corporate debt levels (with debt to EBITDA levels at 15 years high) and the over-optimistic earnings growth estimated by analysts.

That last point may seem harsh given the 24% and 10% growth in reported quarterly EPS and revenue respectively in Q2 2018 over Q2 2017, according to Factset as at 10/08/2018. The graph below shows the quarterly reported growth projections by analysts, as per S&P Dow Jones Indices, with a fall off in quarterly growth in 2019 from the mid-20’s down to a 10-15% range, as items like the tax cuts wash out. Clearly 10-15% earnings growth in 2019 is still assuming strong earnings and has some commentators questioning whether analysts are being too optimistic given the potential headwinds outlined above.

According to Factset as at 10/08/2018, the 12-month forward PE of 16.6 is around the 5-year average level and 15% above the 10-year average, as below. As at the S&P500 high on 21/08/2018, the 12-month forward PE is 16.8.

In terms of the Shiller PE or the cyclically adjusted PE (PE10), the graph below shows that the current PE10 ratio of 32.65 as at the S&P500 high on 21/08/2018, which is 63% higher than 50-year average of 20. For the purists, the current PE10 is 89% above the 100-year average.

According to this very interesting research paper called King of the Mountain, the PE10 metric varies across different macro-economic conditions, specifically the level of real interest rates and inflation. The authors further claim that PE10 becomes a statistically significant and economically meaningful predictor of shorter-term returns under the assumption that PE10 levels mean-revert toward the levels suggested by prevailing macroeconomic conditions rather than toward long-term averages. The graph below shows the results from the research for different real yield and inflation levels, the so-called valuation mountain.

At a real yield around 1% and inflation around 2%, the research suggests a median PE around 20 is reasonable. Although I know that median is not the same as mean, the 20 figure is consistent with the 50-year PE10 average. The debates on CAPE/PE10 as a valuation metric have been extensively aired in this blog (here and here are examples) and range around the use of historically applicable earnings data, adjustments around changes in accounting methodology (such as FAS 142/144 on intangible write downs), relevant time periods to reflect structural changes in the economy, changes in dividend pay-out ratios, the increased contribution of foreign earnings in US firms, and the reduced contribution of labour costs (due to low real wage inflation).

One hotly debated issue around CAPE/PE10 is the impact of the changing profit margin levels. One conservative adjustment to PE10 for changes in profit margins is the John Hussman adjusted CAPE/PE10, as below, which attempts to normalise profit margins in the metric. This metric indicates that the current market is at an all time high, above the 1920s and internet bubbles (it sure doesn’t feel like that!!). In Hussman’s most recent market commentary, he states that “we project market losses over the completion of this cycle on the order of -64% for the S&P 500 Index”.

Given the technological changes in business models and structures across economic systems, I believe that assuming current profit margins “normalise” to the average is too conservative, particularly given the potential for AI and digital transformation to cut costs across a range of business models over the medium term. Based upon my crude adjustment to the PE10 for 2010 and prior, as outlined in the previous Broken Record post (i.e. adjusted to 8.5%), using US corporate profits as a % of US GDP as a proxy for profit margins, the current PE10 of 32.65 is 21% above my profit margin adjusted 50-year average of 27, as shown below.

click to enlargeCAPE Shiller PE PE10 adjusted as at 21082018 S&P500 high

So, in summary, the different ranges of overvaluation for the S&P500 at its current high are from 15% to 60%. If the 2019 estimates of 10-15% quarterly EPS growth start to look optimistic, whether through deepening trade tensions or tighter monetary policy, I could see a 10% to 15% pullback. If economic headwinds, as above, start to get serious and the prospect of a recession gets real (although these things normally come quickly as a surprise), then something more serious could be possible.

On the flipside, I struggle to see where significant upside can come from in terms of getting earnings growth in 2019 past the 10-15% range. A breakthrough in trade tensions may be possible although unlikely before the mid-term elections. All in all, the best it looks like to me in the short term is the S&P500 going sideways from here, absent a post-labor day spurt of profit taking.

But hey, my record on calling the end to this bull market has been consistently broken….

Value Matters

I recently saw an interview with Damian Lewis, the actor who plays hedge fund billionaire Bobby “Axe” Axelrod in the TV show Billions, where he commented on the differences in reaction to the character in the US and the UK. Lewis said that in the US, the character is treated like an inspirational hero, whereas in the UK he’s seen as a villain. We all like to see a big shot hedgie fall flat on their face so us mere mortals can feel less stupid.

The case of David Einhorn is not so clear cut. A somewhat geekie character, the recent run of bad results of his hedge fund, Greenlight Capital, is raising some interesting questions amongst the talking heads of the merits of value stocks over the run away success of growth stocks in recent years. Einhorn’s recent results can be seen in a historical context, based upon published figures, in the graph below.

Einhorn recently commented that “the reality is that the market is cyclical and given the extreme anomaly, reversion to the mean should happen sooner rather than later” whilst adding that “we just can’t say when“. The under-performance of value stocks is also highlighted by Alliance Bernstein in this article, as per the graph below.

As an aside, Alliance Bernstein also have another interesting article which shows the percentage of debt to capital of S&P500 firms, as below.

click to enlarge

Einhorn not only invests in value stocks, like BrightHouse Financial (BHF) and General Motors (GM), but he also shorts highly valued so-called growth stocks like Tesla (TSLA), Amazon (AMZN) and Netflix (NFLX), his bubble basket. In fact, Einhorn’s bubble basket has been one of the reasons behind his recent poor performance. He queries AMZN on the basis that just because they “can disrupt somebody else’s profit stream, it doesn’t mean that AMZN earns that profit stream“. He trashes TSLA and its ability to deliver safe mass produced electric cars and points to the growing competition from “old media” firms for NFLX.

A quick look at the 2019 projected forward PE ratios, based off today’s valuations against average analysts estimates for 2018 and 2019 EPS numbers from Yahoo Finance of some of today’s most hyped growth stocks plus their Chinese counterparts plus some more “normal” firms like T and VZ as a counter weight, provides considerable justification to Einhorn’s arguments.

click to enlarge

[As an another aside, I am keeping an eye on Chinese valuations, hit by trade war concerns, for opportunities in case Trump’s trade war turns out to be another “huge” deal where he folds like the penny hustler he is.]

And the graph above shows only the firms with positive earnings to have a PE ratio in 2019 (eh, hello TSLA)!! In fact, the graph makes Einhorn’s rationale seem downright sensible to me.

Now, that’s not something you could say about Axe!

Heterogeneous Future

It seems like wherever you look these days there is references to the transformational power of artificial intelligence (AI), including cognitive or machine learning (ML), on businesses and our future. A previous post on AI and insurance referred to some of the changes ongoing in financial services in relation to core business processes and costs. This industry article highlights how machine learning (specifically multi-objective genetic algorithms) can be used in portfolio optimization by (re)insurers. To further my understanding on the topic, I recently bought a copy of a new book called “Advances in Financial Machine Learning” by Marcos Lopez de Prado, although I suspect I will be out of my depth on the technical elements of the book. Other posts on this blog (such as this one) on the telecom sector refer to the impact intelligent networks are having on telecom business models. One example is the efficiencies Centurylink (CTL) have shown in their capital expenditure allocation processes from using AI and this got me thinking about the competitive impact such technology will have on costs across numerous traditional industries.

AI is a complex topic and in its broadest context it covers computer systems that can sense their environment, think, and in some cases learn, and take applicable actions according to their objectives. To illustrate the complexity of the topic, neural networks are a subset of machine learning techniques. Essentially, they are AI systems based on simulating connected “neural units” loosely modelling the way that neurons interact in the brain. Neural networks need large data sets to be “trained” and the number of layers of simulated interconnected neurons, often numbering in their millions, determine how “deep” the learning can be. Before I embarrass myself in demonstrating how little I know about the technicalities of this topic, it’s safe to say AI as referred to in this post encompasses the broadest definition, unless a referenced report or article specifically narrows the definition to a subset of the broader definition and is highlighted as such.

According to IDC (here), “interest and awareness of AI is at a fever pitch” and global spending on AI systems is projected to grow from approximately $20 billion this year to $50 billion in 2021. David Schubmehl of IDC stated that “by 2019, 40% of digital transformation initiatives will use AI services and by 2021, 75% of enterprise applications will use AI”. By the end of this year, retail will be the largest spender on AI, followed by banking, discrete manufacturing, and healthcare. Retail AI use cases include automated customer service agents, expert shopping advisors and product recommendations, and merchandising for omni channel operations. Banking AI use cases include automated threat intelligence and prevention systems, fraud analysis and investigation, and program advisors and recommendation systems. Discrete manufacturing AI use cases including automated preventative maintenance, quality management investigation and recommendation systems. Improved diagnosis and treatment systems are a key focus in healthcare.

In this April 2018 report, McKinsey highlights numerous use cases concluding that ”AI can most often be adopted and create value where other analytics methods and techniques are also creating value”. McKinsey emphasis that “abundant volumes of rich data from images, audio, and video, and large-scale text are the essential starting point and lifeblood of creating value with AI”. McKinsey’s AI focus in the report is particularly in relation to deep learning techniques such as feed forward neural networks, recurrent neural networks, and convolutional neural networks.

Examples highlighted by McKinsey include a European trucking company who reduced fuel costs by 15 percent by using AI to optimize routing of delivery traffic, an airline who uses AI to predict congestion and weather-related problems to avoid costly cancellations, and a travel company who increase ancillary revenue by 10-15% using a recommender system algorithm trained on product and customer data to offer additional services. Other specific areas highlighted by McKinsey are captured in the following paragraph:

“AI’s ability to conduct preventive maintenance and field force scheduling, as well as optimizing production and assembly processes, means that it also has considerable application possibilities and value potential across sectors including advanced electronics and semiconductors, automotive and assembly, chemicals, basic materials, transportation and logistics, oil and gas, pharmaceuticals and medical products, aerospace and defense, agriculture, and consumer packaged goods. In advanced electronics and semiconductors, for example, harnessing data to adjust production and supply-chain operations can minimize spending on utilities and raw materials, cutting overall production costs by 5 to 10 percent in our use cases.”

McKinsey calculated the value potential of AI from neural networks across numerous sectors, as per the graph below, amounting to $3.5 to $5.8 trillion. Value potential is defined as both in the form of increased profits for companies and lower prices or higher quality products and services captured by customers, based off the 2016 global economy. They did not estimate the value potential of creating entirely new product or service categories, such as autonomous driving.

McKinsey identified several challenges and limitations with applying AI techniques, as follows:

  • Making an effective use of neural networks requires labelled training data sets and therefore data quality is a key issue. Ironically, machine learning often requires large amounts of manual effort in “teaching” machines to learn. The experience of Microsoft with their chatter bot Tay in 2016 illustrates the shortcoming of learning from bad data!
  • Obtaining data sets that are sufficiently large and comprehensive to be used for comprehensive training is also an issue. According to the authors of the book “Deep Learning”, a supervised deep-learning algorithm will generally achieve acceptable performance with around 5,000 labelled examples per category and will match or exceed human level performance when trained with a data set containing at least 10 million labelled examples.
  • Explaining the results from large and complex models in terms of existing practices and regulatory frameworks is another issue. Product certifications in health care, automotive, chemicals, aerospace industries and regulations in the financial services sector can be an obstacle if processes and outcomes are not clearly explainable and auditable. Some nascent approaches to increasing model transparency, including local-interpretable-model-agnostic explanations (LIME), may help resolve this explanation challenge.
  • AI models continue to have difficulties in carrying their experiences from one set of circumstances to another, applying a generalisation to learning. That means companies must commit resources to train new models for similar use cases. Transfer learning, in which an AI model is trained to accomplish a certain task and then quickly applies that learning to a similar but distinct activity, is one area of focus in response to this issue.
  • Finally, one area that has been the subject of focus is the risk of bias in data and algorithms. As bias is part of the human condition, it is engrained in our behaviour and historical data. This article in the New Scientist highlights five examples.

In 2016, Accenture estimated that US GDP could be $8.3 trillion higher in 2035 because of AI, doubling growth rates largely due to AI induced productivity gains. More recently in February this year, PwC published a report on an extensive macro-economic impact of AI and projected a baseline scenario that global GDP will be 14% higher due to AI, with the US and China benefiting the most. Using a Spatial Computable General Equilibrium Model (SCGE) of the global economy, PwC quantifies the total economic impact (as measured by GDP) of AI on the global economy via both productivity gains and consumption-side product enhancements over the period 2017-2030. The impact on the seven regions modelled by 2030 can be seen below.

PwC estimates that the economic impact of AI will be driven by productivity gains from businesses automating processes as well as augmenting their existing labour force with AI technologies (assisted, autonomous and augmented intelligence) and by increased consumer demand resulting from the availability of personalised and/or higher-quality AI-enhanced products and services.

In terms of sectors, PwC estimate the services industry that encompasses health, education, public services and recreation stands to gain the most, with retail and wholesale trade as well as accommodation and food services also expected to see a large boost. Transport and logistics as well as financial and professional services will also see significant but smaller GDP gains by 2030 because of AI although they estimate that the financial service sector gains relatively quickly in the short term. Unsurprisingly, PwC finds that capital intensive industries have the greatest productivity gains from AI uptake and specifically highlight the Technology, Media and Telecommunications (TMT) sector as having substantial marginal productivity gains from uptaking replacement and augmenting AI. The sectoral gains estimated by PwC by 2030 are shown below.

A key element of these new processes is the computing capabilities needed to process so much data that underlies AI. This recent article in the FT highlighted how the postulated demise of Moore’s law after its 50-year run is impacting the micro-chip sector. Mike Mayberry of Intel commented that “the future is more heterogeneous” when referring to the need for the chip industry to optimise chip design for specific tasks. DARPA, the US defence department’s research arm, has allocated $1.5 billion in research grants on the chips of the future, such as chip architectures that combine both power and flexibility using reprogrammable “software-defined hardware”. This increase in focus from the US is a direct counter against China’s plans to develop its intellectual and technical abilities in semiconductors over the coming years beyond simple manufacturing.

One of the current leaders in specialised chip design is Nvidia (NVDA) who developed software lead chips for video cards in the gaming sector through their graphics processing unit (GPU). The GPU accelerates applications running on standard central processing units (CPU) by offloading some of the compute-intensive and time-consuming portions of the code whilst the rest of the application still runs on the CPU. The chips developed by NVDA for gamers have proven ideal in handling the huge volumes of data needed to train deep learning systems that are used in AI. The exhibit below from NVDA illustrates how they assert that new processes such as GPU can overcome the slowdown in capability from the density limitation of Moore’s Law.

NVDA, whose stock is up over 400% in the past 24 months, has been a darling of the stock market in recent years and reported strong financial figures for their quarter to end April, as shown below. Their quarterly figures to the end of July are eagerly expected next month. NVDA has been range bound in recent months, with the trade war often cited as a concern with their products sold approximately 20%, 20%, and 30% into supply chains in China, other Asia Pacific countries, and Taiwan respectively

click to enlarge

Although seen as the current leader, NVDA is not alone in this space. AMD recently reported strong Q1 2018 results, with revenues up 40%, and has a range of specialised chip designs to compete in the datacentre, auto, and machine learning sectors. AMD’s improved results also reduce risk on their balance sheet with leverage decreasing from 4.6X to 3.4X and projected to decline further. AMD’s stock is up approximately 70% year to date. AMD’s 7-nanonmeter product launch planned for later this year also compares favourably against Intel’s delayed release date to 2019 for its 10-nanometer chips.

Intel has historically rolled out a new generation of computer chips every two years, enabling chips that were consistently more powerful than their predecessors even as the cost of that computing power fell. But as Intel has run up against the limits of physics, they have reverted to making upgrades to its aging 14nm processor node, which they say performs 70% better than when initially released four years ago. Despite advances by NVDA and AMD in data centres, Intel chips still dominate. In relation to the AI market, Intel is focused on an approach called field-programmable gate array (FPGA) which is an integrated circuit designed to be configured by a customer or a designer after manufacturing. This approach of domain-specific architectures is seen as an important trend in the sector for the future.

Another interesting development is Google (GOOG) recently reported move to commercially sell, through its cloud-computing service, its own big-data chip design that it has been using internally for some time. Known as a tensor processing unit (TPU), the chip was specifically developed by GOOG for neural network machine learning and is an AI accelerator application-specific integrated circuit (ASIC). For example, in Google photos an individual TPU can process over 100 million photos a day. What GOOG will do with this technology will be an interesting development to watch.

Given the need for access to large labelled data sets and significant computing infrastructure, the large internet firms like Google, Facebook (FB), Microsoft (MSFT), Amazon (AMZN) and Chinese firms like Baidu (BIDU) and Tencent (TCEHY) are natural leaders in using and commercialising AI. Other firms highlighted by analysts as riding the AI wave include Xilinx (XLNX), a developer of high-performance FPGAs, and Yext (YEXT), who specialise in managing digital information relevant to specific brands, and Twilio (TWLO), a specialist invoice and text communication analysis. YEXT and TWLO are loss making. All of these stocks, possibly excluding the Chinese ones, are trading at lofty valuations. If the current wobbles on the stock market do lead to a significant fall in technology valuations, the stocks on my watchlist will be NVDA, BIDU and GOOG. I’d ignore the one trick ponys, particularly the loss making ones! Specifically, Google is one I have been trying to get in for years at a sensible value and I will watch NVDA’s results next month with keen interest as they have consistently broken estimates in recent quarters. Now, if only the market would fall from its current heights to allow for a sensible entry point…….maybe enabled by algorithmic trading or a massive trend move by the passives!
