SanDisk Corp.'s stock plummeted 5.08% during Tuesday's intraday trading session, marking a significant decline for the storage sector leader.

The sharp pullback comes amid growing analyst skepticism over the sustainability of AI-driven valuations that have propelled SanDisk's meteoric rise. Some analysts have characterized the company's surge from $33 to over $1,400 within a year as potentially unsustainable, arguing the current valuation premium relative to peers lacks fundamental support. Additionally, concerns have emerged about the market's treatment of the company's remaining performance obligations.

The decline occurred alongside broader weakness in the semiconductor and storage sector, with chip stocks pulling back significantly in pre-market and regular trading sessions. The sector-wide selling pressure contributed to SanDisk's downward movement as investors reassessed valuations across the technology space.
