Sandisk Options Market Prices in 12% Post-Earnings Stock Move

The options market is anticipating a significant price swing for Sandisk Corp. (SNDK) following its upcoming earnings announcement on August 5. According to options data from Bloomberg, traders are pricing in a potential move of 12% in either direction after the company reports its results.

Historical Volatility

A review of Sandisk's post-earnings performance reveals a consistent pattern of the stock's actual move exceeding the options market's implied volatility. In four of the last five reporting periods, the share price change was greater than what options traders had anticipated.

This trend suggests that the company's results have frequently surprised investors, leading to higher-than-expected volatility. The historical data for the past five quarters is as follows:

• April 30: Actual move of 21.2% vs. an implied move of 12.0%
• January 29: Actual move of 15.0% vs. an implied move of 12.8%
• November 6, 2025: Actual move of 17.2% vs. an implied move of 17.0%
• May 7, 2025: Actual move of 11.3% vs. an implied move of 11.2%

The only exception in this period was the August 14, 2025, report, where the stock moved 5.8% against a higher implied move of 6.9%.

Market Implications

The implied move is a key metric derived from options prices that reflects market consensus on a stock's potential volatility. A double-digit figure, such as the 12% priced in for Sandisk, indicates that investors are bracing for potentially significant news when the company releases its figures after the market closes on August 5.

Given the stock's recent history of outsized reactions to earnings, market participants will be closely watching to see if this trend of heightened volatility continues. The data underscores the high level of uncertainty and expectation surrounding the upcoming financial disclosure.
