Understanding how implied volatility works for options and how to capitalize on it

Analysis of volatility term structures, which plot implied volatility against option expiration dates, can reveal anticipated market catalysts. For example, Lululemon's term structure indicates higher near-term volatility ahead of its upcoming earnings report on June 5th, while Domino's Pizza's term structure suggests increased volatility in approximately 60 days, aligning with its expected earnings release on July 18th. The article highlights a potential trading opportunity in Intuitive Surgical (ISRG), suggesting that July 18th expiration options may be overpriced due to an incorrect earnings date estimate, and proposes strategies like selling covered calls or trading calendar spreads to capitalize on this discrepancy.

Analysis

The volatility term structure, which maps implied volatility across different option expiration dates, serves as a market-derived indicator of anticipated catalysts. Elevated implied volatility for specific expirations often signals market expectation of significant price movement due to events like earnings. For instance, Lululemon's (LULU) term structure, exhibiting backwardation with 30-day realized volatility around 36%, points to higher implied volatility for near-term options, aligning with its earnings report scheduled for June 5th. Conversely, Domino's Pizza (DPZ), with recent realized volatility below 19%, shows a term structure peaking around 60 days, consistent with its anticipated July 18th earnings. Dick's Sporting Goods (DKS), post its May 28th earnings and Foot Locker acquisition announcement which drove 30-day realized volatility to nearly 70%, now displays a term structure indicating lower volatility expectations over the next six months, though a rise is noted in the 90-180 day tenor, corresponding to its September 4th earnings. A notable anomaly is presented with Intuitive Surgical (ISRG), where July 18th expiration options show significantly higher volatility. While Nasdaq estimates earnings on July 17th and Bloomberg on July 18th, the article posits these dates may be incorrect. Historically, ISRG's Q2 earnings have occurred between July 18th and July 22nd, never before July 18th for Q2, and typically on Tuesdays or Thursdays, making a Friday, July 18th release unlikely, especially considering the July 4th holiday. The higher premium in August options further supports a later date, with the author speculating a July 22nd release. This discrepancy suggests that ISRG July 18th options may be overpriced if the catalyst (earnings) occurs after their expiration.

Key Decisions for Investors

• Investors aligned with the analysis that Intuitive Surgical's (ISRG) Q2 earnings will likely occur after July 18th, potentially on July 22nd, might consider strategies to capitalize on potentially overpriced July 18th options, such as selling covered calls (e.g., July $600 calls) or implementing calendar spreads (e.g., selling July calls/puts against buying August calls).
• Traders should critically evaluate spikes in implied volatility within an asset's term structure, especially when not aligned with definitively confirmed catalyst dates, as these situations can present opportunities arising from market misinterpretations of event timing.
• Utilize the volatility term structure in conjunction with thorough event calendar verification to identify potential discrepancies in option pricing relative to expected catalyst timelines, but exercise due diligence as algorithmic estimates for event dates can be prone to error.
