The Nasdaq shed roughly 580 points in a broad risk-off session, with memory chip names leading declines. Micron (MU) has been growing revenue at ~49% YoY with 39.8% gross margins and $7.59 diluted EPS, suggesting the selloff may be macro-driven rather than fundamental deterioration. Sandisk (SNDK), by contrast, carries a -22.3% net margin and -$11.32 diluted EPS, meaning it enters any drawdown with far less balance-sheet cushion.

The key question is whether today's move is indiscriminate forced selling across memory or a more discerning re-rating of weaker names. If the selloff is macro-driven, MU's strong fundamentals provide a recovery anchor; if it signals a broader memory cycle turn, SNDK's negative earnings make it the more vulnerable leg. Watch whether MU holds recent technical support and how broad credit/risk spreads behave into the close.
