Investors have been piling into the mega-cap tech companies as they build out their AI infrastructure and rain in profits. The growth and influence of these huge companies over the last decade-plus has been astounding. The Mag 7 (NVDA, MSFT, AAPL, AMZN, META, GOOG, TSLA) now account for over 30% of the S&P 500 value. In the meantime, the smaller companies have been left for dead. Nobody has wanted to touch them since roughly the end of the Great Financial Crisis when investors started pulling money from small and mid-sized stocks in favor of the large-caps. At the time it made sense because there was systemic risk in the markets with some companies failing and filing for bankruptcy while others were getting bailed out – namely the big ones. Fast forward 15 years and now the large-cap weighting relative to small-caps is at the same level it peaked at in the Dot-com era. However, this does not mean we are headed for a crash, quite the opposite in fact. It looks more likely that we will have advancement and rotation in the market.
If there was ever a time for small companies to outperform it should be now. We are in the midst of a bull market, the short interest on small-caps (those betting against the stocks) is at record highs, and momentum is turning in their favor. Large and mega-cap companies are still advancing, but over the past few weeks they have done so at a slower pace relative to small and mid-cap stocks. In previous instances when investors were narrowly interested in a handful of stocks and positioning is this extreme, a reversion to the mean takes place. This unwind often comes fast and can catch investors off guard. Whether this results in a major shift or a short-term move remains to be seen, but a move of some kind is likely coming. It would actually be abnormal for small-caps to not assume a leadership role before this bull market is over. From studying previous cycles, we see that during almost every major bull-run small-caps lead at some point for a stretch of time.
Looking under the hood we are noticing several sectors with an abundance of small-cap companies posting strong returns lately. To just take one, let’s look at financials. Investors have been largely wary of buying stock in banks since the Financial Crisis of 2008. For one, they were at the heart of the problem with their disastrous loans, and secondly investing in a bank stock is just not as sexy as buying the company that runs all the computers or makes all the phones. But what many are missing, and the market may already be sniffing out, is that banks are among the most underrated AI trades in the market. And US banks aren’t the only ones leveling up in the AI space. The larger banks from around the world are transforming and benefiting as well. Slowly but surely the entire banking industry has reversed the negative trend that was in place for years and have now been outperforming the overall market for months. This is a sector that was dead money for well over a decade but now they are catching bids from investors who view them as innovators in a changing economic landscape. JP Morgan is rolling out its own Chat GPT tool, Bank of America’s AI assistant is handling billions of customer interactions, and Goldman Sachs is using AI to draft IPO documents. As these banks grow their top and bottom lines, they will likely go on buying sprees as well and gobble up financial technology (FinTech) companies and regional banks. This is pushing up valuations in the whole space. And almost all the players are small and medium sized businesses. Banks have enormous amounts of data, billions of customers, and currently a more relaxed regulatory environment. Conditions that are ripe for AI integrations. These factors could combine to make them hyperscale the way we have seen the tech giants do, by investing in data centers and other AI adjacent products, services and technologies.
If small-cap companies are going to take on a leadership role at some point in this bull market, then this could be a sector that plays a significant role.
