Sector Momentum and Technical Bullishness Drive SNDK’s Surge
Sandisk’s 15.92% intraday surge aligns with a broader storage sector upswing, as Western Digital (WDC) gains 5.45%. While no direct company-specific news is cited, technical indicators scream momentum: a short-term bullish K-line pattern, a MACD crossover above the signal line (2.13 vs. 1.38), and RSI at 68.8 suggest strong buying pressure. The stock’s 52-week high ($61.44) is now breached, triggering algorithmic and retail follow-through. High implied volatility (55.7% on 2025-09-19 $60 calls) and leveraged options trading confirm speculative fervor.

Storage Sector Gains Momentum as WDC Leads with 5.45% Rally
The Technology Hardware, Storage & Peripherals sector is showing renewed vigor, with Western Digital (WDC) surging 5.45% alongside Sandisk’s breakout. While Sandisk’s move is more dramatic, WDC’s rally reflects broader demand for data storage solutions amid AI and cloud computing growth. Both stocks benefit from sector-wide tailwinds, though Sandisk’s 15.92% gain suggests a more aggressive re-rating driven by technical momentum and options-driven speculation.
