Hi Product Hunt!

I’m an engineer and options trader, and I built Stackfini to solve a problem I kept running into: most options scanners begin with premium, while I wanted to begin with the underlying company.

Stackfini scans the market for cash-secured put opportunities on companies a trader may actually be comfortable owning if assignment occurs. It filters the noise and evaluates factors such as:

• Underlying quality and market conditions
• Assignment-risk context
• Estimated annualized return
• Liquidity and execution
• Downside protection and cash collateral
• Analyst sentiment and earnings exposure

The results are presented as clear, ranked research ideas instead of an overwhelming options chain. The interface is designed to be beginner friendly, while still offering useful detail, filters, saved views, relevant news, and updates multiple times throughout the market day.

There’s also a public cash-secured put calculator that can be used without creating an account.

Stackfini is a research and educational tool—not a source of personalized investment advice or guaranteed trade recommendations.

I’d especially appreciate feedback on:

• Whether each option idea is easy to understand
• Which measurements are most useful when evaluating a CSP
• What would make the research workflow more valuable

Thanks for taking a look. I’ll be here to answer questions and learn from your feedback!
