Implied volatility
RARE is currently trading with moderate implied volatility, broadly in line with other large-cap stocks. On the options we scanned that was around 32% implied volatility, and higher implied volatility means richer premiums and wider expected moves.
Options on RARE currently price in about 32% implied volatility, versus roughly 46% the stock has actually realised over the past month. That makes options relatively cheap — an edge for strategies that buy premium, such as long calls, long puts and debit spreads.
RARE's IV Rank is 0/100: implied volatility sits 0% of the way between its 20-day low (32%) and high (141%), and is above 0% of recorded days. Premium is historically cheap, which favours net-debit strategies like long options and debit spreads.
Off that volatility, the options market is pricing a move of about ±$2.56 (±10%) in RARE by 2026-09-18 — a range of roughly $23.58 to $28.7. Strikes inside that band hold most of the premium and see most of the action.
Across strikes, downside puts on RARE trade at a higher implied volatility than upside calls — the market is paying up for crash protection. That skew favours selling put spreads or buying calls over symmetric trades.
RARE insider trading activity (SEC Form 4)
Open-market insider transactions at RARE over roughly the last six months, from SEC Form 4 filings. Open-market buys are the rarer, more telling signal — routine selling under pre-arranged plans is common, so read a net-selling figure with that in mind.

Earnings & IV crush
RARE's next earnings report is due around November 3, 2026. Options that expire after it price in a binary move, so their implied volatility is elevated and usually collapses right after the announcement — an "IV crush". If your expiration falls before this date, the trade sidesteps the event.
Key figures
- Market cap
- $2.5B
- 52-week range
- $18.29–$39.89 (36% up the range)
- Short interest
- 14.1% of float · 4.2 days to cover
With 14.1% of RARE's float sold short, squeeze and gap risk are elevated — one reason its options can stay expensive.
