Barclays and Goldman Sachs Warn Stock Market Rally May Be Running Out of Steam

TLDR

• Barclays says its equity timing indicator is deep in sell territory, making index put options cheap and worth buying
• Semiconductors make up roughly 19% of the S&P 500, and tech hardware pushes that above 30%
• Goldman Sachs partner Bobby Molavi says greed has overtaken fear, with the S&P 500 hitting record highs 11 times in May alone
• Individual stocks like Intel, Arm, and Dell saw extreme short-term gains, suggesting markets have priced in best-case scenarios
• Broadcom’s post-earnings drop shows even good results can disappoint when expectations are already sky-high

Barclays is warning investors that the current stock market rally has left little room for error. The bank’s equity timing indicator has moved deep into sell territory, and analysts say the risk of a sharp drop now outweighs the chance of further gains.

Because of that imbalance, Barclays says index put options are unusually cheap right now. The bank is recommending investors consider buying them as protection, particularly on the S&P 500 or semiconductor ETFs.

Semiconductors Now Dominate the S&P 500

One reason for the concern is how concentrated the index has become. Semiconductors alone now make up about 19% of the S&P 500. Add in technology hardware, and those two categories account for more than 30% of the index.

That means the S&P 500 no longer behaves like a broad market index. Its performance is increasingly tied to a small group of AI, chip, and tech hardware companies.

If that sector pulls back, the damage could spread quickly. Many funds, ETFs, and institutional portfolios hold the same leading stocks. A simultaneous drop would push index-wide correlation higher and amplify volatility.

Barclays also points out that a semiconductor selloff could pull down the Magnificent Seven. Investors in AI trades tend to hold the whole tech chain, not just individual names. If chips fall, overall AI risk exposure often gets cut at the same time.

Greed Has Overtaken Fear, Says Goldman Sachs

Goldman Sachs partner Bobby Molavi recently said that global investor optimism has overtaken doubt, and that prices have started to deviate from value.

The numbers back that up. The S&P 500 hit a record high 11 times in May alone. The index rose for 10 straight weeks and nine trading days in a row.

Individual stock moves were even more extreme. Arm rose 100% in 10 trading days. Dell gained 93% in six days. Intel climbed 180%. Marvell jumped 32% in a single session after comments from Nvidia CEO Jensen Huang, then added another 10% after hours. Sandisk is up roughly 600% year-to-date.

Those kinds of moves suggest markets have moved beyond pricing in a soft landing or rate cuts. They now reflect an accelerating AI investment narrative where everything is expected to keep going up.

Broadcom Drop Is a Warning Sign

Broadcom’s recent earnings report was not bad. But the stock fell anyway. Analysts say that is what happens when a stock has already priced in strong growth — good results are not enough. The market needs results that beat the most optimistic forecasts.

Goldman Sachs describes this as a profit-driven bubble rather than a valuation expansion bubble. The companies can keep growing, but stock prices will not automatically follow if earnings do not exceed elevated expectations.

For now, Barclays and Goldman Sachs both suggest the risk-reward has shifted. Buying protection through put options on the S&P 500 or semiconductor ETFs may make sense for investors who do not want to be exposed to a sudden reversal. For long-term holders of diversified stocks, simply staying the course remains a valid option.
