Fastly Options Market Braces for 17% Swing on November Earnings

The options market is signaling a significant price swing for Fastly Inc. (NYSE: FSLY) following its upcoming earnings announcement. Traders are pricing in a potential 17% move in either direction for the stock after the company reports its quarterly results on November 4, according to options data compiled by Bloomberg.

Historical Volatility

This level of expected volatility is notable, but Fastly's stock has a history of even larger post-earnings movements. The stock's actual price change has exceeded the options-implied move in six of the past eight earnings announcements, suggesting that even a 17% swing could be conservative based on recent precedent.

Past earnings reactions have been dramatic and demonstrate the stock's sensitivity to its quarterly performance reports. Notable examples include:

Ad

• February 11: Shares surged 82.5%, vastly exceeding the 15.0% implied move.
• November 5, 2025: The stock rose 32.3% compared to an implied move of 15.5%.
• May 6: The stock fell 20.8%, slightly more than the 18.3% move priced in by options.
• August 7, 2024: Shares dropped 27.8% versus an implied move of 24.8%.

Market Context

The high implied volatility reflects uncertainty among investors ahead of the report, which is scheduled for release after the market closes. The significant gap between expected and actual price moves in past quarters underscores the potential for surprise in Fastly's results or forward-looking guidance, creating a high-risk, high-reward scenario for positions held through the announcement.
