“Maybe the ‘great rotation’ pertains less to stocks versus bonds than it does between large- and small-cap equities,” Stovall said in a note.

A Fed rate hike would also help support the U.S. dollar, which would make U.S. exports more expensive overseas and diminish revenue for larger companies with a bigger international footprint. In contrast, small-cap stocks are focused on domestic markets, and Stovall noted that growth projections for U.S. small-caps are better than those for large-cap stocks.

“In the past 36 months, the S&P 500 has recorded a 0.72 monthly correlation with the U.S. Dollar Index (DXY) versus a correlation of 0.55 for the S&P SmallCap 600,” Stovall added.
