Reason: The whole cohort rode the day's broad memory/NAND sector rally (per the day's cohort read) - MU +6.1%, STX +6.34%, WDC +5.86%, SIMO +8.7% on the day - re-accelerating a basket that remains deep pullbacks in massively intact secular uptrends. MU's trend was upgraded to strong-up and its 1-year change extended further to +718.44% (was +665.77%, still 67.6% above its 200-day); SIMO's 1-year change rose to +215.65% (was +197.05%); STX and WDC held roughly flat on the year while still well above their 200-day (43.1% and 25.4% respectively).
