Risk: Low to MediumNeutral to mildly bullishBeginner

Cash-Secured Put

Buy stocks cheaper or collect premium

In a cash-secured put, you sell a put option on a stock you'd like to own at a lower price. You keep enough cash on hand to buy the shares if necessary. The option premium is credited to your account immediately. If the option is exercised, you buy the shares at the strike — effectively at a lower price than today (strike minus premium). If it expires worthless, you simply keep the premium.

FAQ

Frequently Asked Questions

How do I choose the strike for a cash-secured put?

Choose a strike at which you genuinely want to buy the stock — typically 3-7% below the current price. Lower strikes offer less premium but more cushion. Higher strikes (closer to the price) offer more premium but more assignment probability. A delta of 0.20-0.35 (corresponding to ~20-35% assignment probability) is considered a balanced starting point.

What is the difference between a cash-secured put and a naked put?

In a cash-secured put, you hold the full capital (strike × 100) as collateral to buy the shares if assigned. In a naked put, no equivalent collateral is held — the broker provides margin capital. Naked puts require margin accounts and are often not permitted for retail investors at German brokers. The risk profile is identical; the difference lies in the capital structure.

When should I roll a cash-secured put?

Rolling makes sense when (a) the stock has fallen below your strike and you don't want to be assigned, or (b) the option has little time value left but you want to earn a new premium. Buy back the old option and sell a new one with a later expiration and/or lower strike for a net credit. Avoid rolling when the stock's fundamentals have deteriorated — in that case, assignment might be the better outcome.

How much capital do I need for a cash-secured put?

You need the strike price × 100 shares as collateral. Example: put on SAP with strike €220 = €22,000 capital tied up per contract. You can subtract the premium received — if you receive €3.00 premium, it's effectively €21,700. This capital requirement makes cash-secured puts on expensive stocks (SAP, ASML) more capital-intensive than on lower-priced stocks.

What is the optimal term for cash-secured puts?

Most traders prefer 2-6 weeks (14-45 days to expiration). In this range, theta decay is most efficient — the option loses more time value per day than longer-dated options. Very short terms (< 14 days) offer little absolute premium; very long ones (> 60 days) offer little flexibility. 30-45 DTE is a good compromise for most underlyings.
