The Dow's relative resilience suggests more defensive, dividend-oriented corners of the market are holding up better. When the gap between the Nasdaq and the Dow widens like this during a down session, it typically reflects pressure on the higher-valuation, higher-multiple stocks that have driven index-level gains.

With roughly half the session remaining, the key question is whether buyers step in at current levels or whether the indexes drift closer to their intraday lows. The S&P 500's intraday low so far has touched a decline of about 0.6%, and the trend line through the morning shows no decisive stabilization yet.
