SanDisk had previously hit a low of $1325.03 on July 17th, representing a maximum drawdown of 43.7% from its peak; the latest closing price has rebounded by 20.0% from the low but remains 32.5% below the high.

According to Hyperinsight monitoring, the previously tracked "Stock Market Big Winner" whale has heavily positioned itself in this round of rebound, starting from zero at 1:29 p.m. today, buying 22,910.2 shares through 5380 transactions at an average price of $1548.2 by 4:50 p.m.; including existing orders, planning to invest $90 million.
