The S&P 500 was sitting at 7,702 at midday, down about 0.6% from its previous close.

The Dow Jones Industrial Average was barely in the red, off less than 0.1% at the same moment. When the S&P 500 drops noticeably while the Dow barely moves, the selling tends to be concentrated in the large-cap growth and technology names that carry heavy weight in the S&P but less so in the price-weighted Dow.

The trajectory heading into the final hours of trading will indicate whether sellers are in control or afternoon buyers are willing to step in at current levels.
