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 28 out of 100 (LOW). That score is driven by an upcoming earnings report, 5 recent news items, 1 active legal filing, 1 recent SEC event and 16 clinical-trial catalysts falling inside the 4-week window. On TickerRisk's scale anything below 45 is LOW, meaning no major scheduled catalyst was found in this window. That is not a guarantee against an unscheduled move — it means the calendar is clear, not that BIIB cannot fall.

BIIB shows an IV Rank of 59, putting implied volatility in the middle of its one-year range — options are moderately priced, with a current implied volatility of about 41%. IV Rank is the most useful figure for deciding whether to sell or buy premium on BIIB.

The 2026-10-29 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 59 with implied volatility around 41%, alongside a TickerRisk options-risk score of 28/100. BIIB's options are priced near the middle of their own yearly range — unremarkable volatility, so the trade has to stand on its own thesis rather than on rich or cheap premium.

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

BIOGEN INC. (BIIB) next earnings date — 2026-10-29

The next BIIB report lands on 2026-10-29 — about 53 days away — inside the window a typical monthly option would span. BIIB's IV Rank is currently 59. 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.
