Many observers are noting similarities between the current meteoric rise in the US stock market and the late 1990s internet bubble, fueled now by artificial intelligence. Despite concerns about a slowing labor market, sagging consumer sentiment, trade uncertainty, geopolitical tensions, and a US government shutdown, the market continues to reach new record highs. Some veteran Wall Street analysts are experiencing "dot-com deja-vu," with some having warned about a bubble for years. Interactive Brokers' chief strategist, Steve Sosnick, highlights a "generational breakdown" where older investors who experienced the internet bubble are having flashbacks, while younger investors tend to buy dips.
However, there are significant differences. Bloomberg columnist Nir Kaissar argues this market is not like the dot-com bubble, emphasizing that stocks primarily care about earnings growth. Wall Street analysts expect 95% of S&P 500 companies to grow earnings next year by an average of 16%. Similarly, Real Investment Advice points out that the current rally is earnings-led, not multiple-led, with second-quarter S&P 500 earnings growing roughly 31% year-over-year. AI-related names drove almost 60% of the index's earnings growth, and three hyperscalers are projected to account for approximately 70% of full-year analyst expectations, funded by cash flow.
The cyclically adjusted price-to-earnings (CAPE) ratio, a traditionally reliable metric, has reached its second-highest level in history at around 41, just shy of the dot-com era's peak of 44. While a high CAPE often signals expectations of massive future earnings growth, it doesn't necessarily predict a market crash. The Motley Fool advises that a high CAPE is a reminder to be selective, favoring companies with strong balance sheets, durable earnings, and reasonable valuations, while diversifying holdings and resisting the urge to chase the next "big thing." Investors are encouraged to keep investing, as potential market dips could offer opportunities to buy quality stocks.
Anthropic's AI warning may impact chipmaker and AI-linked stocks in the short term, but the long-term outlook for computing infrastructure spending remains strong. Demand for chips, energy, and computing power continues to outstrip supply, suggesting any weakness in these sectors may be short-lived. The Nasdaq is up over 20% since its March 30 low, and the Philadelphia Semiconductor Index is also performing strongly. While some parts of the market show narrowing leadership, with small caps falling more than large caps, the overall sentiment remains cautiously optimistic due to strong earnings and investor positioning.
