Is it risky to sell options on BIOGEN INC. (BIIB) right now?

For a 4-week expiry, BIOGEN INC. (BIIB) carries an options catalyst-risk score of 84 out of 100 (HIGH). That score is driven by an upcoming earnings report, 6 recent news items, 1 active legal filing and 14 clinical-trial catalysts falling inside the 4-week window. On TickerRisk's scale 70 and above is HIGH, so a known event is scheduled inside this window — selling premium on BIIB here is a bet on that event rather than on time decay. The score measures scheduled event exposure, not which way the stock will move.

BIIB shows an IV Rank of 90 — implied volatility is near the top of its own one-year range, so BIIB options are historically expensive, which favours premium-selling strategies, with a current implied volatility of about 49%. IV Rank is the most useful figure for deciding whether to sell or buy premium on BIIB.

The 2026-10-28 earnings report sits inside a standard monthly expiry for BIIB, so implied volatility should stay bid into the date and drop sharply once it passes.

BIOGEN INC. (BIIB) current implied volatility and IV Rank

BIOGEN INC. (BIIB) currently has an IV Rank of 90 with implied volatility around 49%, alongside a TickerRisk options-risk score of 84/100. That's high — options are expensive relative to the past year, which favours premium-selling strategies such as credit spreads, iron condors and covered calls, provided no binary catalyst is working against you.

For what this number does and does not tell you about BIIB's options, see IV Rank explained.

BIOGEN INC. (BIIB) next earnings date — 2026-10-28

The next BIIB report lands on 2026-10-28 — about 7 days away — inside the window a typical monthly option would span. BIIB's IV Rank is currently 90. That matters more than any other single date on the calendar: the stock can gap overnight on the print, and any premium you collect now is partly payment for carrying that gap. Sellers who want the volatility crush without the gap generally choose an expiry that ends before the report.
