Stock investors don’t need to look hard to find warnings that the market looks frothy after a 36% surge from April’s nadir pushed valuations to levels associated with prior periods of exuberance.

For much of the past two months, relative calm in the derivatives market has served as a handy retort to those worries, with Cboe’s Volatility Index clocking in well below its long-term average. Even under the hood, at the single-stock level, moves have been uncorrelated to a degree last seen in February – a sign of health to most market watchers.

That argument, though, suffered a blow recently when the VIX started creeping higher at the same time individual correlations remained muted. The VIX’s jump above 17 was viewed as a sign among derivatives traders that institutional investors are worried any stumble in the AI trade that’s powered gains all year could lead to a market-wide drawdown.

“One of the things I look for is, are the periods where they start to diverge, where VIX stops going down, even if correlations decline,” said Interactive Brokers Group Inc. chief strategist Steve Sosnick. “There is more nervousness out there, people are buying stocks but holding their nose. Don’t fight the tape, but insure against it.”

Dip buyers emerged Wednesday, when the S&P 500 rebounded from a sharp drop and the VIX slipped back below 17 on virtually no news. Tech led the way, as has been the case for the entire year. And that is the main reason for low correlation among single stocks: the outsize impact from the AI trade.

Huge gains in the likes of Oracle Corp. and Advanced Micro Devices Inc. drive the market higher, while slumps in consumer shares and perceived AI losers like Salesforce Inc. have kept breadth low. The concentration of gains in AI behemoths has left the virtually all of the S&P 500’s advance this year down to around 10 companies.

A few weeks before Apple Inc., Alphabet Inc., Microsoft Corp. and the rest of the tech giants report earnings, derivatives traders are adding protection in case any one of them misses the mark.

“If there is any disappointment there, the market does not have broader fundamental backing to help support these gains,” Sevens Report’s Tom Essaye and Tyler Richey wrote in a client note on Tuesday, referring to AI driven stocks specifically.

The pair believe it won’t take much for waning AI enthusiasm to trigger a 5% drop in the S&P 500.

There are a few ways investors can buy protection. Investors often use bearish options on the Invesco QQQ Trust ETF as a way to buy protection against a fall in the Nasdaq 100 Index, which the fund tracks.

“The more prudent place to buy insurance is the Nasdaq 100 than the S&P 500 because they correlate rather well, except the Nasdaq 100 tends to be the more volatile of the two,” said Sosnick. Because the Nasdaq tends to move more aggressively than the S&P 500, options on the tech index are slightly more expensive.

But for investors who don’t want to fiddle with derivatives themselves, there are now hundreds of exchange-traded funds that do just that. Defined outcome ETFs like the JPMorgan Nasdaq Equity Premium Income ETF owns megacap tech stocks, but also includes downside protection against a market plunge.

More adventurous traders can look to VIX ETFs, like the 2x Long VIX Futures ETF. Such funds can triple in days in the event of a market sell off, before rapidly plunging back to earth, and are ruinously expensive to hold for longer periods of time.

But setting money aside to pay hedging costs could be wise, said Sosnick.

“The more AI-centric you were in April, the worse you did.”
