Why Is Sandisk (SNDK) Stock Price Up 10.99% Today, Sep 18? S&P 100 Inclusion and $41M Call Buying Lift Shares

AI Market Summary
SanDisk (SNDK) surged 10.99% ahead of its S&P 100 inclusion, a catalyst that can drive mechanical index-fund buying around the rebalance window. Reported $41M in bullish call purchases likely added momentum via dealer hedging, reinforcing a broader rebound in memory and semiconductor names. Near term, flows tied to index implementation and options positioning may elevate volatility as the market tests whether demand persists beyond one-off catalysts.
