Reading an Earnings Calendar with Options Data
Earnings reports create a known event date, but the direction and size of a stock move remain uncertain. This calendar brings dates and available option snapshots into one table. It does not rank trades by expected profit or identify mispriced options.
Choose Dates, Then Check Coverage
- Select a UTC date range of up to 31 days and apply it. Quick date presets change the draft dates; Apply Filters loads them. Reset loads the current UTC week.
- Search the loaded company names or symbols, or filter by sector and market capitalization. Companies with unknown sector or market cap cannot satisfy those filters.
- Read the expiration and data-coverage notes. Options are fetched for the visible page in batches, with a maximum of 250 contracts per event. A partial chain may omit the closest strike or a useful expiration. Sorting only reorders the visible page.
- Confirm the report date with the company and inspect executable bid/ask quotes at your broker. Apply filters again to reload; the page does not stream market data.
Current IV for an Expiration After Earnings
Nearest-expiry IV averages available call and put IV at the loaded strike closest to the reference stock price. Event-expiry IV uses the first loaded expiration strictly after the earnings date. Same-day expirations are excluded because the release may occur after the options trading session. If the loaded subset has no later expiration, the value stays unavailable.
Both columns are observations made now. An option expiring after earnings still includes uncertainty before the announcement; its current IV is not a forecast of post-announcement IV. IV can fall when uncertainty resolves, but that change is neither fixed nor guaranteed.
Straddle Cost Is Not an Earnings Forecast
The cost percentage is (call daily close + put daily close) / reference stock price × 100. The contracts use the same strike and event-spanning expiration. Both daily bars must have timestamps on the same UTC date. Reference spot and option closes may still be asynchronous or stale, and the calculation omits spreads, fees and execution effects.
For a hypothetical $100 reference stock price and $8 combined premium, the cost percentage is 8%. A long straddle held to expiration breaks even at strike plus or minus the actual premiums paid, before fees. An 8% cost percentage is not a claim that the stock will move 8%, nor a calibrated probability range. The option lifetime can include many days beyond earnings.
Historical Moves Need Release Timing
The historical sample considers up to 12 prior reports supplied by the provider. A before-market report uses the preceding trading close to the report-day close. An after-market report uses that day’s close to the next trading close. Unknown release times are excluded, and missing price windows are not filled with zero. The table reports the sample count.
The average is the mean absolute close-to-close percentage change for the available timed events. It includes other market news in those windows, is not an earnings-only causal effect, and is not directly comparable to a multi-day option cost as a fair-value test. A small or incomplete sample cannot establish a trading edge.
