$MU $SNDK $SKHYNIX Storage opens tonight: most stocks turn green, but it cannot yet be defined as a reversal After the U.S. stock market opened tonight, the storage sector did not continue to collectively plunge but showed a clear differentiated recovery. ✔ SK Hynix ADR rose about 2.9% ✔ SanDisk rose about 1.2% ✔ Western Digital and Seagate both rose about 0.8% ✔ Micron fell about 0.8% ✔ Nvidia rose about 0.9% On the surface, most stocks turned green, but the sector is not consistent internally. SanDisk received a buy rating with a target price of $1600, combined with last week's continuous sharp decline, driving an oversold rebound in NAND and HDD directions; SK Hynix ADR performed the strongest, indicating that the HBM and undervaluation logic still have capital support. But the real focus remains on Micron. Micron once surged to 877.5 after the open, then quickly fell back to around 845, and has not yet stood back above the previous closing price. This indicates that capital is willing to bottom-fish flash memory and SK Hynix but is still cashing out high-position chips in Micron. ✔ Key prices tonight Micron: 845 support, 870–878 resistance SanDisk: 1230 support, 1285 resistance Western Digital: 432 support, 448–450 resistance SK Hynix ADR: 135–136 support, 140–141 resistance For the storage sector to upgrade from "oversold recovery" to "trend reversal," Micron first needs to firmly stand above 870–878, while SanDisk and SK Hynix ADR break through their opening highs. For SK Hynix contracts, tonight's ADR rise will bring short-term rebound pressure, so I will not chase shorts near 1000. If the rebound is blocked again at 1015–1030, consider adding positions; 1045–1055 remains a more ideal strong resistance zone. On the downside, only breaking below 980–970 will reopen 950; if 950 continues to fail, the final target looks at 930. ✔ Trading iron rule Never bet on the first candlestick of the open, because the win rate could be zero. Tonight's open has again proven: prices can first surge, then plunge sharply, and then continue to rebound. Let the first round of long-short clearing end, then decide based on resistance and support. My judgment remains unchanged: tonight is an oversold recovery, not a trend reversal. The rebound only provides position, it does not mean the overall direction has changed.
