Western Digital Corporation closed at $447.18 on September 12, 2026, a decline of 3.03% from the prior session. The move extended a stretch of selling pressure that has weighed on the data storage company's shares across multiple timeframes.
Over the past seven days, WDC has fallen 4.31%, and the 30-day loss now stands at 9.30%. The consecutive declines across each measured period signal sustained downward momentum in the stock.
Western Digital's market capitalization stood at $166.18 billion as of the close. The company remains one of the larger players in the storage hardware sector by market value, even as its share price has retreated from higher levels over the past month.
The back-to-back losses across the one-day, seven-day, and thirty-day windows paint a consistent picture of recent selling activity in WDC shares, with the stock now sitting meaningfully below where it traded a month ago.
