Analysis

The options market for Ultragenyx Pharmaceutical Inc. (RARE), currently trading at $29.05, presents two distinct income-generating strategies. Selling the May 2026 cash-secured put at a $27.50 strike offers an effective cost basis of $24.55 if assigned, representing a notable discount to the current share price. Alternatively, if this out-of-the-money put expires worthless, which has a 66% probability according to current data, the seller would realize a 16.45% annualized return on the cash commitment. For existing shareholders, selling the May 2026 covered call at a $32.50 strike generates immediate premium. If the stock is called away, the total return would be 23.92%; if it expires worthless (a 45% probability), the premium provides an 18.48% annualized yield boost. A key analytical insight is the significant spread between the options' high implied volatility (68%-70%) and the stock's lower trailing twelve-month historical volatility (51%), suggesting that option premiums are currently rich relative to the stock's recent price behavior, enhancing the appeal of option-selling strategies.

Key Decisions for Investors

• Investors interested in acquiring RARE at a lower price could sell the May 2026 $27.50 put to either purchase the stock at an effective cost of $24.55 or generate a 16.45% annualized yield.
• Current RARE shareholders can consider selling the May 2026 $32.50 covered call to generate an 18.48% annualized yield, but must accept capping their total return at 23.92% if the stock is called away.
• The elevated implied volatility of 68-70% compared to the 51% historical volatility indicates that option-selling strategies are currently favorable, as they allow for harvesting inflated premiums.
• Traders should note that the covered call strategy forgoes all potential gains above the $32.50 strike price, a significant risk if the stock rallies substantially before expiration.
