Canonical HTML page: https://theoptionsbench.com/learn/your-first-cash-secured-put/ --- Last updated 27 May 2026 · by Theo Chen **The big idea:** A cash-secured put is getting paid to wait to buy a stock you already want - at a price below where it trades today. This is the trade the whole course builds toward. A Cash-Secured Put is four simple decisions. Make them in order and the rest takes care of itself. You can run the numbers alongside this lesson in the Cash-Secured Put Calculator. Want to go deeper? The dedicated Cash-Secured Puts course takes this strategy from mechanics to managing a live position across six focused lessons. ## Step 1 - Pick a stock you'd genuinely own Start with the company, not the premium. Choose a stable business or broad ETF you'd be happy to hold for years. The test: if you woke up owning 100 shares at your strike, would you be content? If not, wrong stock. ## Step 2 - Pick a strike below today's price The strike is the price you're willing to buy at. Setting it below the current price means you're asking for a discount before you'll buy. To gauge the odds, Sellers lean on delta - a number your broker shows for every option that, for a Put, conveniently doubles as a rough chance of being assigned. A strike around 0.20-0.30 delta means loosely a 20-30% chance of assignment; about 30-45 days to expiry is the usual sweet spot - enough premium to be worth it, without tying your cash up for months. How to choose a strike price goes deeper. ## Step 3 - Set aside the cash Reserve **strike × 100** in cash per contract. That reservation is what makes the Put "secured" rather than naked. A $50 strike ties up $5,000. If your broker would let you sell it on margin without the cash, don't - that's a different, riskier trade we don't do here. ## Step 4 - Know the three outcomes - Stock stays above the strike: the Put expires worthless, you keep the entire premium, and you repeat. - Stock sits right at the strike: pin risk - you might or might not be assigned. Usually a non-event for a stock you'd own. - Stock falls below the strike: you're assigned and buy 100 shares at the strike, using the cash you reserved. Your effective cost is the strike minus the premium. ### A worked example You'd happily own XYZ, trading at $52. You sell one 30-day $50 Put for $1.20. You reserve $5,000. If XYZ stays above $50, you keep $120 - about 2.4% on the cash in a month. If XYZ drops to $46, you buy 100 shares at $50, but your real cost is **$48.80** ($50 - $1.20) - better than buying at $52 today, on a stock you wanted anyway. Your first trade as three outcomes along the stock price: a flat win above the strike, pin risk right at it, and assignment below - where the $1.20 premium drops your real cost to $48.80. ## The clearest way to see it: a paid limit order | | Limit order to buy | Cash-Secured Put | | Goal | Buy the stock at a lower price | Get paid while waiting to buy lower | | If the stock never dips | Nothing happens | You keep the premium | | If it reaches your price | You buy the shares | You're assigned the shares | | Income along the way | None | The premium, upfront | | Best used when | You have a target buy price | You're happy to own it and understand assignment | Common beginner mistake Selling the Put without actually reserving the cash. That turns a defined, secured trade into a Naked Put - the same position with margin and a much uglier worst case. The cash sitting idle _is_ the strategy. ## Key takeaways - A CSP is four steps: own-worthy stock -> strike below price -> reserve strike × 100 in cash -> manage the three outcomes. - Assignment isn't failure: your effective cost is the strike minus the premium you collected. - Think of it as a limit order to buy a stock you want - that pays you while you wait. ## Pop quiz - solidify your understanding How much cash must you set aside for one Cash-Secured Put? The strike price times 100 - enough to buy 100 shares if you're assigned. A $50 strike means $5,000 reserved per contract. What are the three things that can happen at expiration? The stock stays above the strike (you keep the full premium), it sits right at the strike (pin risk - you may or may not be assigned), or it's below the strike (you're assigned and buy the shares). What is your effective purchase price if assigned? The strike minus the premium you already collected. Sell a $50 Put for $1.20 and your cost basis on assignment is $48.80. ## Frequently asked questions How do I choose the strike price? A common conservative starting point is a strike around 0.20-0.30 delta - roughly a 70-80% chance of expiring worthless - and 30-45 days out. Lower strikes are safer but pay less. See the strike-selection guide for the full reasoning. What return can I expect? It's the premium divided by the cash reserved, then annualized. The Cash-Secured Put Calculator does this for you, including your effective cost basis if assigned. Treat the annualized figure as a comparison aid, not a promise. Can I close the Put early instead of waiting for expiration? Yes - many Sellers buy it back once they've captured most of the premium (e.g. 50%), freeing the cash to redeploy. You never have to hold to expiration.
