Good morning. Stocks were mixed on Friday, while the Tech (XLK) sector declined, capping a volatile week.

Neocloud provider CoreWeave (CRWV) sank 6%, reversing gains from Thursday amid continued worries over AI financing.

AI semiconductor giants Nvidia (NVDA) and AMD (AMD) were on pace to end the week lower. Memory giants Micron (MU) and SK Hynix (SKHY) also declined, along with flash memory maker Sandisk (SNDK), following a broader sector sell-off earlier in the week.

Meanwhile, Tesla (TSLA) stock popped after the EV maker’s jaw-dropping Roadster event.

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.
