Good morning. Stocks were mixed on Tuesday as semiconductor names gave up the prior session’s rebound and oil prices rose.

Brent crude oil futures (BZ=F) hovered near a five-month high at $110 per barrel, while WTI (CL=F) traded just below $100 in the aftermath of attacks from Houthi rebels against Saudi Arabia amid an ongoing Middle East conflict.

The Tech (XLK) sector declined, led by chipmakers like Nvidia (NVDA) and AMD (AMD). Memory makers Micron (MU) and SK Hynix (SKHY) also declined as Monday’s rebound in the AI trade fizzled.

Shares of neocloud provider CoreWeave (CRWV), which were hammered last week over fears of AI financing, declined after attempting a rebound on Monday.

Here’s a check of the markets in the first few minutes of trading, based on a heat map powered by Yahoo Finance AlphaSpace data.
