The first full trading week of May ended with the broader S&P 500 index having gained 2.33%. Notably, stocks continued climbing despite what Fundstrat’s Washington Policy Strategist Tom Block described as a continuing stream of “mixed messages” from the White House about the status of the Iran war.
Yet this advance is not due to the kind of irrational exuberance that often precedes a bubble bursting. On the contrary, as Fundstrat Head of Research Tom Lee put it, “in our view, the U.S. stock market is rising for the right reasons.“
Some of the most closely watched companies have reported their quarterly earnings, and the results thus far have pleased Lee. We are 88% through earnings season, and 86% of those that have reported are beating estimates, with a magnitude of surprise hitting 18.4%. Lee told us companies are essentially beating at “the largest margin that we have seen in more than a decade.”
Yet as Head of Data Science Ken Xuan noted during our weekly huddle, that figure might be “kind of distorted” by the results being reported by the likes of Amazon and Google. The possibility of this sort of tech stock-driven distortion is on the mind of Head of Technical Strategy Mark Newton, too.
To be clear, the exuberance being seen in AI-related parts of the market is understandable to Newton. “Demand seems to still be outpacing supply by about 30%” when it comes to semiconductors and parts of memory and optics, he suggested, so “I don’t think the exuberance being shown for those stocks is something to get too concerned about.” Still, in his view, “we need to see the broader market play catch up,” noting “the lack of rallies out of healthcare and financials and [consumer] discretionary.”

Chart of the Week

Fundstrat’s Tom Lee pointed out this week the companies leading this rally are companies that produce things in scarce supply – companies that have strong fundamentals. This includes AI compute components, AI power generation components, petroleum products (jet fuel and diesel), and scale computing enterprises. It also explains why Korea (KOSPI) has outperformed since the outset of the Iran war. South Korea’s stock market is dominated by AI hardware – think Samsung and memory companies like SK Hynix, for example.
