Is it risky to sell options on COSTCO WHOLESALE CORP /NEW (COST) right now?

COSTCO WHOLESALE CORP /NEW (COST) currently scores 79 out of 100 for options catalyst risk (HIGH) over a 4-week expiry window. What pushes it there: an upcoming earnings report, 2 recent news items and 10 active legal filings, all landing inside the 4-week window. Anything at 70 or above counts as HIGH, meaning the premium on COST is at least partly compensation for a scheduled event rather than pure time value. It says nothing about direction — only that something is on the calendar.

COST shows an IV Rank of 34, near the low end of its one-year range — options are relatively cheap, which favours option buyers over sellers, with a current implied volatility of about 27%. Read IV Rank alongside the catalyst score: it says how expensive COST options are, while the score says whether that price is justified by a scheduled event.

COST reports on 2026-09-24. Any expiry beyond that date carries the gap, and the implied volatility priced in beforehand typically collapses the morning after.

COSTCO WHOLESALE CORP /NEW (COST) current implied volatility and IV Rank
