Moderna Options Market Prices in 4.2% Swing for July 31 Earnings

Options traders are pricing in a potential 4.2% move in either direction for Moderna Inc. (MRNA) shares following the company's quarterly earnings report, scheduled for release before the market opens on July 31. This expectation is based on an analysis of options data compiled by Bloomberg.

Historical Volatility

The implied move derived from options pricing serves as a market gauge for anticipated volatility, but it is not always predictive of the actual outcome. An analysis of Moderna's last eight earnings reports shows the stock's actual price swing has exceeded the implied move on three occasions.

In several recent instances, the post-earnings reaction has been significantly more pronounced than what the options market had priced in, particularly to the downside. Notable examples include:

• May 1, 2026: Shares fell 14.2%, surpassing an implied move of 9.2%.
• August 1, 2025: The stock declined 18.8% versus an expected 7.6% move.

Context for Investors

The largest post-earnings move for Moderna in the past two years occurred on August 1, 2024, when the stock plunged 20.3%, far exceeding the 7.9% swing anticipated by options traders at the time, according to the data.

Conversely, the stock's reaction can also be more muted than expected. Following the February 13, 2026, earnings release, shares gained just 3.3% against a much larger implied move of 9.6%. This historical data provides context for investors on the potential for significant price volatility surrounding the company's financial disclosures.
