Western Digital Corporation shares closed at $323.71 on Thursday, November 5, 2026, a decline of 6.78% over the prior 24 hours. The move added to an already steep pullback for the stock, which carries a market capitalization of $130.02 billion.
The single-session loss deepened a broader trend of weakness. Over the past seven days, WDC shed 18.34%, and the 30-day decline reached 26.71%, reflecting sustained selling pressure across recent weeks.
The consecutive losses across all three measured periods — daily, weekly, and monthly — paint a consistent picture of downward momentum for the data storage company. No single session or short-term event accounts for the full scope of the drawdown, as the losses have accumulated steadily over the trailing month.
Western Digital, a maker of hard disk drives and flash storage products, has seen its market value erode significantly from levels seen 30 days prior. At $130.02 billion in market capitalization, the company remains a large-cap name, though the recent price action has weighed meaningfully on that figure.
