Long Put

Single1 legdebitbearish

Buy a put. A bearish position or a hedge, with a defined cost — and the other side of every cash-secured put sold on this platform.

What it is

You buy the right to sell 100 shares at the strike. The cost is the premium; the gain grows as the stock falls, bounded only by the stock reaching zero.

It serves two quite different purposes: a directional bearish bet, or insurance on shares you own. The structure is identical; the intent is not.

This is the counterparty to a cash-secured put. Someone buying this is paying for the right to hand you shares at the strike — which is precisely what you were paid to accept.

How it is built

Priced off the guide's shared chain, on a $50 stock. Every figure beneath the diagram is computed from these legs by the same engine the Strategy Builder uses.

Collateral held: $260 — the gross amount tied up, before the premium received.

A single $50 put bought for $2.60. Flat at the debit above the strike, rising as the stock falls below the break-even at $47.40. This is the position on the other side of every cash-secured put — what the buyer pays for is the right to put shares to you.

Reading the shape

Flat at the debit above the strike.

A break-even at the strike less the premium, then rising as the stock falls further.

How it is used

As a hedge over 100 shares it defines a floor for a known cost over a known period — a protective put. The cost is continuous: the protection expires and has to be repurchased.

As a directional position it suits a bearish view with a timeframe, with the loss capped at the premium.

Lower implied volatility makes it cheaper, which is why protection is least expensive precisely when it feels least necessary.

Seeing what a put buyer pays makes the cash-secured put's premium legible: you are being compensated for taking on exactly the risk they are paying to shed.
Rolling protective puts indefinitely is expensive, and the running cost is easy to underestimate over a year.
Time decay works against it, so a slow decline can still lose money.
