yahoo news | AI Stocks Just Did Something That's Been Witnessed Only 4 Times in 62 Years --...

The surge of artificial‑intelligence technology is being hailed as the next economic breakthrough after the internet, with analysts estimating a global opportunity of more than $15 trillion by 2030. AI has already propelled the Dow, the S&P 500 and the Nasdaq to record heights, largely driven by firms such as Nvidia, whose GPUs dominate data‑center deployments, and Palantir, whose AI‑powered platforms have rallied over 2,200 % since early 2023. For the first time since 1964, the ten largest AI stocks now make up roughly 41 % of the S&P 500—a concentration level that has historically preceded major market corrections and, according to the article, should make Wall Street sound a warning bell.

That warning is grounded in three previous instances when a single sector or group accounted for a similar share of an index: the “Nifty Fifty” in the early‑1970s, a Japanese‑stock concentration in the late‑1980s, and the tech‑telecom bubble of the early 2000s. Each episode featured aggressive valuations—price‑to‑earnings ratios in the 50‑100 range for the Nifty Fifty and a Shiller P/E of 44.19 on the eve of the dot‑com crash. Today’s AI leaders are similarly pricey, with Palantir’s price‑to‑sales topping 100 and Nvidia’s P/S above 30, suggesting that the current upside may be built on borrowed time rather than sustainable earnings.

Adding to the risk is the fading “scarcity premium” that has underpinned AI hardware pricing. Nvidia’s dominance has relied on a shortage of GPUs, allowing it to command high prices and margins. However, major cloud providers are now designing their own chips, and competitors such as AMD are ramping up production, eroding Nvidia’s pricing power and potentially deflating the broader AI‑stock rally. The article concludes that while AI’s long‑term promise remains strong, investors should treat the present concentration and valuation levels as a red flag and consider whether it’s finally time to sound the alarm.
