Priced for Perfection: S&P 500 Increasingly Dependent on the AI Trade

BCM 4Q24 Market and Strategy Commentary – Decathlon Strategies

2024 was a spectacular year for U.S. equity indices, but only a normal one for the typical stock which pulled back appreciably in December. Headline equity performance continued to be driven by the very largest of, primarily U.S., Technology companies. Increasing prospects of a “soft landing” in the economy as well as enthusiasm over AI technology encouraged overall investor optimism throughout the year.

After the U.S. election, this optimism boiled into something more akin to speculation as Trump’s firm victory ushered in the prospect of potentially lower taxes and less regulation. The prices of cryptocurrencies surged as did those of the most speculative companies, such as tiny firms engaged in the far from economically viable technology of quantum computing. These companies saw their share prices increase anywhere from 5 to 20 times in a matter of weeks[1].

We’ve spoken about the gamification of markets at times over the past 5 years and continue to believe it has created material distortions in parts of the market as retail trading remains extremely accessible and popular. The financial industry has sought to capitalize on this with the proliferation of 0-day options and the release of cryptocurrency and single stock levered ETFs[2]. This type of “innovation” is often a tell-tale sign of speculation just as the wave of SPACs and IPOs proved to be at the end of 2020 into 2021.

The current backdrop is highly reminiscent of 2021, and we believe 2025 might look a bit like 2022, albeit with some mitigating factors:

  1. Stocks look expensive and have done anomalously well.
  2. Broad speculation has returned to markets and investors are very bullish.
  3. Inflationary pressure may be upward.
