Sandisk (NASDAQ:SNDK) Stock Price Up 7.4% - Still a Buy?

Key Points

• Shares jumped 7.4% to $486.50, hitting all‑time highs on a momentum/technical breakout despite slightly below‑average intraday volume and a market cap of about $73.5 billion.
• The rally is being driven by AI‑driven storage demand, NAND/DRAM supply tightness that supports pricing power, and a wave of analyst upgrades and price‑target raises that have attracted institutional buyers.
• Key risks include an extremely stretched valuation (P/E ~1,566), warnings the stock is overbought, and an upcoming earnings print that could sharply reverse gains; consensus is a "Moderate Buy" with an average target near $327.89 but wide analyst dispersion.
