Negative-beta stocks in the S&P 500 hit a record high

MarketWatch says the growing share of stocks moving opposite the index points to higher single-day volatility than S&P 500 performance alone suggests.

Stocks in the S&P 500 are increasingly trading in opposite directions from the index on the same day, and the number of negative-beta names has reached a new record high, according to MarketWatch.

The outlet frames the shift as a sign that market volatility may be running higher than investors would infer from the index level itself, since the internal stock moves are diverging more than the headline index return suggests.
