SNDK (7.17)

Judging from the weekly and daily cycle structure, after an initial spike up, SanDisk has entered a trend reversal phase. Since rebounding from the historical high of 2354, it has been persistently under the EMA30 daily moving average. Over the medium term, the moving-average system has shifted from dispersion to gradual convergence, then turned, forming a suppressive bearish alignment. During the rebound process, it has repeatedly tested the moving averages but failed to effectively hold above them; the medium-term upward momentum has completely declined.

From the momentum indicator perspective, the MACD DIF and DEA lines have continued to fall after a high-level “dead cross.” The red histogram bars quickly narrow and gradually turn green, with clear signals that the bearish (downside) momentum is decreasing. The 14-period RSI has fallen from the overbought zone back to a neutral-to-bearish area. Short-term rebounds lack strength to recover; the lower boundary of the medium-term core strong support zone is around 1280. This level is the central hub of concentrated positions before the launch of this AI market cycle. If short-term sentiment selling pressure continues, this area is likely to be probed down to confirm.

Recommendation
Bearish at 1390-1420, target 1325, then 1280.
For the long term: 1190-1120.
