Sandisk Joins the Nasdaq 100 Today. The Stock Slips.

Sandisk (SNDK) officially joined the Nasdaq 100 on Monday, becoming part of the US Tech 100 index. The move comes after a dramatic rally—Sandisk has surged roughly 2,990% over the past year as data-center demand boosted memory-product sales—but shares slipped in early trading on the day of inclusion. Index membership can prompt rebalancing flows from funds and ETFs that track the US Tech 100, potentially affecting both Sandisk liquidity and short-term price action, even as long-term demand dynamics remain supportive for memory suppliers.
