Investors are increasingly buying put options on the Russell 2000 Index, a direct bet against further small-cap gains, even as enthusiasm for mega-cap AI stocks remains intense. This divergence signals growing caution within segments of the market.

The hedging activity points to specific worries about smaller companies' sensitivity to interest rates and economic slowdowns. Their valuations often hinge on future profit growth, which looks less certain amid sticky inflation and potential earnings misses.

Meanwhile, the AI trade continues to propel the S&P 500 and Nasdaq, driven by a handful of tech giants. This creates a two-speed market where safety is sought in the smallest stocks while the largest names power forward on transformative technology hopes.

The dynamic suggests institutional investors are managing risk by protecting against a small-cap reversal while staying exposed to the dominant AI momentum, a tactical shift with implications for portfolio construction and market breadth.
