The storage sector was “blacklisted” by today’s “Black Wednesday” ordeal, with SanDisk’s single-day drop exceeding 9%, wiping out more than half of the gains from last week’s Investor Day. $SNDK

From a professional perspective, the essence of this pullback is “expectation-gap trading”: $MU
- SanDisk’s Q4 financial report shows a gross margin of 84.6%, already at a historic peak, but guidance has fallen back to 83%-85%. The market believes the slope of earnings growth has topped out; $SKHYNIX
- The increase in NAND contract prices is starting to slow. A Bernstein July tracking report shows that the Q3 rise is clearly narrower than Q2, and the marginal effect of the pricing logic is weakening;
- In terms of the volume-price relationship, currently only prices are rising without any acceleration in shipping volume. Management has not provided an incremental growth rationale, causing capital to question the forward-looking growth prospects.

But the good news is: NBM long-term contracts have already locked in the base for the next four years—8 major customers, RMB 93.9 billion in minimum-guarantee contracts, and 50% of production capacity locked in for 2027. These are real cash-flow floors. Storage is shifting from traditional cyclical stocks to “long-term contracts + AI” growth stocks.

Don’t rush to bottom-fish in the short term—wait until $1400-1500 stabilizes. A good company doesn’t mean it can be bought at any price.
