Memory stocks are closing the week on a high note after a brutal November slump. Micron $MU ( ▲ 4.66% ) , Seagate $STX ( ▲ 4.95% ) , Western Digital $WDC ( ▲ 4.9% ) , and flash memory maker Sandisk $SNDK ( ▲ 7.11% ) are all trading sharply higher, with each name up between 4 percent and 6 percent on Friday.
Three of the four had fallen roughly 20 percent last month as credit risk crept into AI trades and speculative momentum unwound across smaller AI-linked names. Sandisk took the biggest hit and has recovered the least.
Micron, Western Digital, and Seagate have bounced back more convincingly and now sit within about 5 percent of their all-time highs. Sandisk continues to lag.
While GPUs and TPUs dominate headlines, data centers also need massive amounts of memory to store and feed information to these processors. The rebound reflects renewed confidence in the supporting cast behind the AI infrastructure buildout.
