Semiconductor Rout Deepens as Nasdaq Enters Correction; Dow Rises on Earnings
The Nasdaq 100 fell into correction territory Tuesday as a deepening chip rout intensified on concerns over rising Chinese competition in memory chips. Meanwhile, the Dow Jones surged, lifted by strong earnings from Coca-Cola and Sherwin-Williams, and the S&P 500 edged higher.
The S&P 500 is heavily weighted by mega-cap tech and semiconductor stocks, so a prolonged semiconductor downturn drags on the index even as defensive and consumer staples sectors provide support.
A brutal selloff in memory and semiconductor stocks, triggered by Chinese competition fears and a crash in South Korea's KOSPI, has pushed the Nasdaq into correction, while defensive sectors and earnings winners lift the Dow.

Market Prices Significant Odds of Surprise Fed Rate Hike at July Meeting
