Why Is SanDisk Stock Crashing, and is it a Generational Buying Opportunity?

SNDK has collapsed roughly 64-65% since June 2026, and the damage traces to one driver: rising regulatory risk that spooked investors. That is a drawdown of nearly two-thirds in a matter of months, and it has split the analyst community into two camps.

One side calls the selloff a generational buying opportunity. The other sees a value trap, where a cheap-looking price masks a deteriorating risk profile. The source frames the debate without resolving it, which tells you the market has not settled on what the regulatory threat is worth.

A hard date sits on the calendar. SNDK is executing an 8-for-1 stock split on November 19, 2026. A split changes the share count and per-share price, not the company's underlying value, so it does not alter the regulatory picture. Interpretation: after a 64-65% slide, the lower per-share price post-split may draw retail attention, but that is a flow story, not a fundamental fix.

The setup is binary in character. If regulatory fears ease, a stock down this far has room to rebound sharply. If the risk escalates, the same drawdown can extend. The source offers no evidence yet pointing either way.
