How a cash-secured put on SQ works
A cash-secured put on SQ means you set aside cash equal to strike × 100 × contracts — the maximum you'd owe if assigned. In exchange you receive premium up front. For the full setup, delta-selection rules, and assignment management, read the complete cash-secured puts guide.
Three outcomes:
- SQ stays above the strike at expiry → the put expires worthless; you keep the premium and your cash.
- SQ closes below the strike at expiry → you buy 100 shares per contract at the strike. Effective cost basis = strike − premium.
- Stock drops well below the strike → you still buy at the strike, taking an unrealized loss equal to (strike − market price) per share, partially offset by the premium received.
Why SQ for a CSP
High implied volatility — meaningful premium income but watch position sizing. SQ does not currently pay a dividend, so ex-dividend early-assignment risk on short calls is not a concern.
For wheel-strategy traders, SQ is a workable wheel candidate. The high implied volatility — meaningful premium income but watch position sizing means cash-secured puts collect meaningful premium, and the underlying business profile (Financial — Fintech) makes it a name many income sellers would be comfortable being assigned at the right strike.

FAQ
How is annualized ROC calculated for a SQ CSP?
Annualized return on capital = (Premium ÷ Cash secured) × (365 ÷ days to expiration). Cash secured equals strike × 100 × number of contracts.
What's the effective cost basis if my SQ put is assigned?
Effective cost basis = strike − premium received. That's the actual price per share you pay if assigned, usually below the strike and often below the current market price. The CSP cost-basis deep-dive walks through the math with worked examples.
What strike should I sell on SQ?
Pick a sub-spot strike you would genuinely be comfortable owning SQ at. The Top 10 ranking helps surface candidates; ROC alone isn't enough — you need to want the assignment outcome at that price. The CSP delta-selection guide covers the trade-offs.
