Tesla vs. Amazon: A Mostly Harmless Investment?

by

The market, as it frequently does, has decided to briefly resemble a startled herd of wildebeest. This, naturally, sends investors scurrying about, desperately seeking stocks that haven’t entirely given up the ghost. Two contenders, both sporting impressive technological ambitions and currently experiencing a minor gravitational disagreement with the upward trajectory, are Tesla (TSLA 2.70%) and Amazon (AMZN +0.16%). Both, it seems, are rather keen on Artificial Intelligence, which, depending on your perspective, is either the future of everything or a remarkably efficient way to make toasters ask existential questions.

Down approximately 12% and 10% respectively (at the time of writing, which, as anyone who understands the universe knows, is a fleeting moment in spacetime), these stocks present a compelling opportunity for those brave enough to venture into the somewhat unpredictable world of public markets. But which one? That, as they say, is the question. (It’s also the answer, if you consider the inherent circularity of existence.)

Tesla: The Autonomous Vehicle and the Slightly Less Autonomous Future

Tesla recently reminded us, with the subtlety of a supernova, that it’s transitioning from merely building electric cars to becoming a full-fledged Artificial Intelligence entity. They’ve announced progress in their “Full Self-Driving” (Supervised) program, boasting a 38% year-over-year increase to 1.1 million subscribers. They’ve even begun removing safety monitors from their Robotaxis in Austin. This is either a stroke of genius or a demonstration of breathtaking optimism. (The distinction, much like Schrödinger’s cat, remains somewhat blurred until observed.)

The problem, however, isn’t the ambition. It’s the current state of the, shall we say, conventional automotive business. Tesla’s total automotive revenue declined by 11% year over year in the fourth quarter, falling to $17.7 billion. Operating margins also experienced a slight dip, from 6.2% to 5.7%. (This is, of course, entirely normal. All large organizations experience temporary setbacks, usually involving misplaced staplers and existential crises.)

Still, they’re not entirely devoid of cash. Tesla generated $1.4 billion in free cash flow during the quarter, although that’s a bit down from the $2.0 billion of the previous year. (Free cash flow is, essentially, the money left over after you’ve paid for everything. It’s a surprisingly useful concept, especially if you happen to be a large corporation.) They also saw record deployments of energy storage, driving a 25% year-over-year increase in energy generation and storage revenue to $3.8 billion. (Energy storage, naturally, is where you put the energy when you’re not using it. It’s a surprisingly elegant solution.)

Amazon: A Diversified AI Powerhouse (and a Remarkably Efficient Delivery System)

Amazon, meanwhile, appears to be having a rather good time. The e-commerce and cloud computing giant posted fourth-quarter net sales of $213.4 billion, a 14% year-over-year increase (or 12% excluding the whims of currency exchange rates). Even better, Amazon Web Services (AWS) is booming, with revenue surging 24% year-over-year to $35.6 billion – representing about 17% of total revenue. (AWS is, essentially, a very large collection of computers in a building. It’s surprisingly complicated.)

This top-line strength translated into robust profitability. Amazon’s overall operating income rose 18% year-over-year to $25.0 billion. Management’s relentless focus on efficiency across its North America fulfillment network is clearly paying off. (Efficiency, of course, is the art of getting more done with less. It’s a surprisingly satisfying pursuit.)

Amazon is also actively capitalizing on the AI revolution, not only through AWS but also with its chip business. Their proprietary custom chips, Trainium2 and Graviton architectures, are driving massive scale and now represent an annual revenue run rate of over $10 billion. (Chips, of course, are tiny pieces of silicon that do all the clever stuff. They’re surprisingly fragile.) They are also projecting net sales between $173.5 billion and $178.5 billion for the first quarter, implying a growth rate of around 13% year-over-year.

The Better Buy (or, a Mostly Sensible Investment)

Both of these are fast-growing, impressive businesses. However, one stock appears to be the slightly less risky option at the moment. Amazon, trading at around 29 times earnings, seems reasonably priced compared to Tesla’s rather lofty price-to-earnings ratio of approximately 360. (Price-to-earnings ratios are, essentially, a way of figuring out if a stock is expensive or not. It’s surprisingly subjective.) Given Amazon’s strong momentum across e-commerce, digital subscriptions, cloud computing, and advertising, it presents a more compelling value proposition.

Tesla, at its current valuation, seems to have already priced in a successful and rapid rollout of its autonomous ride-sharing network, leaving very little room for error. (Error, naturally, is an inherent part of the universe. It’s surprisingly common.) Amazon offers investors access not only to potential growth from cloud computing but also to solid growth in its existing operations, coupled with a more attractive valuation.

Of course, investing in Amazon isn’t without risks. A weak macroeconomic environment could affect multiple parts of its business simultaneously. Weaker discretionary spending could weigh on retail and advertising, and an uncertain business environment could impact enterprise cloud spending. Regulatory risks, given its size, are also a factor. And soaring capital expenditures to support AI infrastructure will likely impact free cash flow in the near term. (Capital expenditures, naturally, are the money spent on building things. It’s surprisingly expensive.)

Still, I lean towards Amazon. Its valuation does a much better job of factoring in risks than Tesla’s. It’s not a guaranteed win, of course. (Nothing is, really. Except maybe taxes.) But it’s a mostly sensible investment in a decidedly nonsensical world.
