7.25 SanDisk analysis

The board shows a standard bearish alignment, with price under pressure below the Bollinger downward channel. The current spike breaks through the lower band at 1480.41 to draw in buyers, but the RSI three-periods synchronously falls below the 30 threshold, entering a multi-timeframe oversold dulling state. The negative deviation rate BIAS has diverged to an extreme value, and the short-term bearish narrative now faces a need for microstructure repair. In terms of trading logic, if the price cannot effectively break through 1480 and trigger short-covering, the probability of a mean-reversion rebound toward the mid-band at 1560 will increase; conversely, if it breaks that support with volume, it will open up recursive downside space, directly testing the liquidation-level support at 1456. It is recommended to watch whether the 15-minute K-line can form a bottom fractal confirmation, and to wait for a second sell point after liquidity hunting.

Trading suggestion: range 1530-1560, target 1460-1400.
