SanDisk Corp.

(NASDAQ:SNDK) is set to report fiscal fourth-quarter (Q4) 2026 earnings Wednesday after the close, and options markets are pricing an unusually large move for the S&P 500's best-performing stock of the year.

According to Benzinga Pro data, the implied earnings move stands near 16% in either direction.

From Tuesday’s $1,427 close, that translates into a potential move toward roughly $1,655 on the upside or $1,199 on the downside.

That's about a $228 swing either way.
