SanDisk is drawing aggressive long-term institutional buying that supports further upside. It posted its largest dollar buy volume ever at $1,646.55, a sign of institutions building a long-term position, and weekly high-dollar volume of $140B off the recent low supports a six-month upside continuation pattern. Selling from all-time highs looks inefficient, the monthly trend is bullish, and over $140M went into August 28 $900 calls. x.com x.com x.comÂ
