There's plenty of red to be found on traders' screens today, with the S&P 500 recently off 1.7% and the more tech-focused Nasdaq Composite dropping about twice as much.

The Dow, on the other hand, is holding up. The blue-chip index was up about 0.6% in afternoon action. That's despite a big pullback in shares of chip maker Nvidia (NVDA), which joined the index late last year.

So what's sustaining the Dow? At recent count, 20 of its 30 components were in the green, with even the smallest gainer—Sherwin-Williams (SHW), which joined at the same time as Nvidia—rising some 0.7%. Healthcare and staples stocks, including such names as Johnson & Johnson (JNJ), Procter & Gamble (PG) and Coca-Cola (KO) were among the best performers.

But there was some tech in there, too: Apple (AAPL), which is scheduled to report quarterly results later this week, was recently up 3.7%. That came as CNBC's index of Magnificent Seven stock slid nearly 4%.

Meanwhile, Monday's moves have the Dow outperforming the other two major indexes for the year so far—though underperforming them over the past 12 months.
