SanDisk shares face volatility amid institutional risks and US policy shifts

SanDisk shares are experiencing significant volatility driven by both institutional positioning and shifting US political considerations. An analysis by Morgan Stanley identified the stock as ‘over-owned’ by institutional investors relative to its S&P 500 weighting, creating a risk of disproportionate sell-offs if many fund managers attempt to exit positions simultaneously. This institutional concentration contributed to a sharp decline in share price, with the stock falling approximately 9 percent following an 8.1 percent drop on August 18.

Adding to the market pressure, reports indicate the US government under Donald Trump is considering allowing Apple to source memory chips from Chinese manufacturers, specifically DRAM from CXMT and NAND flash from YMTC. This potential policy shift represents a direct threat to the business models of US-based memory manufacturers like SanDisk, whose NAND flash business could face increased competition. The possibility of a regulatory reversal follows recent statements from Commerce Secretary Howard Lutnick and pressure from US Senators to restrict such sourcing, highlighting the high level of political risk currently impacting the semiconductor sector.
