A surge in market dispersion is signaling another shift in leadership within U.S. equities and could pave the way for a broader market rally beyond mega-cap technology stocks, according to a Stifel note.

Dispersion, which measures the volatility of individual stocks relative to overall index volatility, recently climbed to record highs even as broader market volatility remained subdued — a situation that is unlikely to persist.

Since the end of May, the equal-weight S&P 500 .SPXEW has outperformed the market-capitalization-weighted benchmark .SPX, helped by gains in previously lagging sectors such as healthcare and banks. Semiconductor stocks and the so-called Magnificent Seven technology companies lagged during that period.

In recent weeks, however, Mag-7 stocks have resumed leadership at the expense of other momentum trades, while stock-specific volatility has continued to rise, according to Stifel. That suggests another leg of market rotation may be approaching.

Several potential catalysts remain that could lead to increased volatility in July, including the upcoming Federal Reserve policy meeting, earnings reports from high-spending Mag-7 companies, employment data and geopolitical tensions in the Middle East.
