Is it risky to sell options on COSTCO WHOLESALE CORP /NEW (COST) right now?
COSTCO WHOLESALE CORP /NEW (COST) currently scores 48 out of 100 for options catalyst risk (MEDIUM) over a 4-week expiry window. What pushes it there: an upcoming earnings report, 4 recent news items and 10 active legal filings, all landing inside the 4-week window. MEDIUM covers 45 to 69: there is something on COST's calendar worth reading before you pick an expiry, without it dominating the trade. Direction is not part of what the score measures.
COST shows an IV Rank of 20, 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 23%. 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 2026-12-10. 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
COST is trading at an IV Rank of 20 with implied volatility around 23%, alongside a TickerRisk options-risk score of 48/100. That's low — options are cheap relative to the past year, which favours premium-buying strategies such as long calls, long puts and debit spreads when you expect a move.

COSTCO WHOLESALE CORP /NEW (COST) next earnings date — 2026-12-10
COSTCO WHOLESALE CORP /NEW (COST) is scheduled to report on 2026-12-10 — about 50 days away, so a standard expiry would carry straight through it. COST's IV Rank is currently 20. Implied volatility tends to build into the date and drop sharply once results are public. If the premium on COST looks unusually generous right now, this is the most likely reason.
