Western Digital Stock Drops Tuesday: Here's Why - Western Digital (NASDAQ:WDC)

Western Digital (WDC) shares fell 6.78% to $411.69 on Tuesday.

Investors worry about increased competition and thinner margins for Western Digital. Last week, Toshiba announced plans to double its hard drive output for AI data centers by 2027, further pressuring WDC and STX shares.
