A cash-secured put is a short-put position fully collateralized by cash. The trader sells a put — typically slightly out-of-the-money — and sets aside enough cash to buy 100 shares per contract if assigned. The trader collects premium up front. If the stock stays above the strike, the put expires worthless and the premium is kept. If the stock finishes below the strike, the trader is assigned and buys the shares at the strike minus the premium already collected.

    Cash-Secured Put

    A cash-secured put is a short-put position fully collateralized by cash. The trader sells a put — typically slightly out-of-the-money — and sets aside enough cash to buy 100 shares per contract if assigned. The trader collects premium up front. If the stock stays above the strike, the put expires worthless and the premium is kept. If the stock finishes below the strike, the trader is assigned and buys the shares at the strike minus the premium already collected.

    Quick definition

    A strategy that sells a put option while holding enough cash to buy the shares if assigned. The cash-secured put earns premium up front and either keeps the premium or acquires stock at an effective discount.

    Why traders use it

    The cash-secured put is a way to get paid for waiting to buy a stock you were going to buy anyway. It provides a defined-outcome entry: either premium income or share acquisition at an effective discount. It also enforces discipline — the trader commits to a specific price, at a specific size, before entering, rather than chasing dips emotionally.

    Risk profile

    The risk is the same as owning the stock outright from the strike minus premium collected — if the underlying craters, the assigned position takes losses just like any long stock position. Cash-secured puts do not create leverage; they simply front-load part of the return as options premium. Selling puts against stocks you would not want to own is the fastest way to turn this strategy into a disaster.

    How Treeova uses it

    Treeova's cash-secured put agents run the strategy end-to-end: strike selection based on delta and IV Rank, position sizing that respects buying power, and post-assignment handoff into a covered-call or holding-period rule. The wheel strategy — cash-secured put → assignment → covered call → assignment out — is a first-class agent archetype in the Trading Workspace.
