Secure 25.1% Annualized Returns: Buy 89bio at $7.50 Using Options Strategy

Exploring Put Options on 89bio Inc: A Strategic Investment Insight

Investors eyeing a purchase of 89bio Inc (Symbol: ETNB) shares may hesitate at the current market price of $8.34 per share. However, they might find value in considering an alternative strategy: selling puts. One particularly intriguing option is the December put at the $7.50 strike, which, at the time of writing, has a bid price of $1.45. Collecting this premium yields a return of 19.3% against the $7.50 commitment, translating to an impressive 25.1% annualized rate of return, a concept we refer to as the YieldBoost at Stock Options Channel.

Understanding the Dynamics of Selling Puts

It’s important to note that selling a put does not allow an investor to gain from the potential upside of ETNB shares as owning the stock would. The put seller only acquires shares if the contract is exercised. The counterparty benefits from exercising the contract at the $7.50 strike only if it provides a better outcome than selling shares at the current market price. For this option to be exercised, 89bio Inc’s stocks must drop by 10.8%. If the contract is exercised, the effective cost basis would be $6.05 per share (after accounting for the $1.45 premium). Consequently, the primary advantage for the put seller lies in collecting the premium, capitalizing on that 25.1% annualized return.
