Western Digital Surges 2.73%: AI Storage Tailwinds or Technical Rally?

Summary
• WDC trades at $174.175, up 2.73% intraday, hitting a 52-week high of $178.45
• Intraday range spans $168.90–$174.91, with $169.54 previous close
• Sector leader Sandisk (SNDK) mirrors WDC’s 2.7% rally, signaling broader hardware sector momentum

Western Digital’s sharp intraday rally has ignited speculation about AI-driven storage demand and technical momentum. With the stock trading near its 52-week peak and the Fed’s final 2025 rate decision looming, investors are dissecting whether this surge reflects fundamental strength or speculative fervor. The computer hardware sector’s synchronized move adds urgency to the debate.

AI Storage Demand and Technical Momentum Drive WDC's Rally
Western Digital’s 2.73% intraday surge aligns with escalating demand for AI storage solutions, as global data centers expand capacity to meet generative AI workloads. The stock’s ascent to $174.175—a 2.73% gain from $169.54—reflects optimism around WDC’s role in supplying high-capacity drives for AI infrastructure. Technically, the stock’s break above the 30-day moving average ($156.71) and its position near the upper Bollinger Band ($176.28) suggest a short-term bullish trend. Analyst upgrades, including a recent 'Strong Buy' from China Renaissance, further amplify momentum.

Computer Hardware Sector Rally: WDC and SNDK Lead AI-Driven Storage Surge
The computer hardware sector has surged in tandem with WDC’s rally, led by Sandisk (SNDK), which also rose 2.7% intraday. Both stocks benefit from AI’s insatiable appetite for high-performance storage. While WDC’s 52-week high of $178.45 and 286.78% YTD return outpace SNDK’s 235.13% YTD gain, the sector’s synchronized move underscores shared tailwinds. Analysts highlight that AI-driven data center expansion is the primary catalyst, with WDC’s 44TB external drives and Sandisk’s enterprise SSDs positioned to capture market share.
