Protective Put

Wheel2 legsdebitbullish

Own shares and buy a put beneath them. Insurance on a holding — a known cost for a known floor, with the upside left intact.

The Strategy Builder does not construct this one — the reference shelf is broader than the picker. You can still build it by hand: add the legs below in the builder's leg table.

What it is

You own the stock and buy the right to sell it at a chosen strike. Below that strike your losses stop; above it you keep the shares' full upside.

Also called a married put when bought at the same time as the shares. Mechanically it is identical to a long call at the same strike — put-call parity again.

The premium is a genuine cost, paid whether or not the protection is needed. That is what makes it insurance rather than a trade.

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: $650 — the gross amount tied up, before the premium received.

That net figure includes buying the shares. The option premium on its own is −$150 received.

100 shares at $50 with a $45 put bought for $1.50. The left tail goes flat at the put strike — that is the floor. Unlike a collar, the right side keeps rising: nothing has been sold, so no upside was given away. The $1.50 is what that costs.

Reading the shape

Flat at maximum loss below the put strike: the shares' fall is offset one-for-one by the put's gain.

Rising without a cap above the break-even, which sits at the share basis plus the premium paid.

The same shape as a long call, which is exactly what the combination synthesizes.

How it is used

It suits a holding you want to keep through a period you are wary of, where selling would trigger tax or forfeit a position you believe in longer-term.

Strike choice is the deductible. A put close to the money costs more and protects sooner; a further one is cheaper and lets more of the fall through first.

The cost is continuous rather than one-off, which is the figure most often underestimated. Protection rolled every quarter has an annual running cost worth calculating explicitly.

Since this synthesizes a long call, compare the two directly. If the call at the same strike is cheaper than the stock-plus-put, the call is the more efficient way to hold the same exposure.
Paying for protection repeatedly on a position that never falls is a real, cumulative drag on returns — and it is invisible in any single diagram.
It is the opposite posture from the rest of this platform. A premium seller collects for accepting risk; here you are paying to shed it.

Like everything in this guide, these are descriptions of structures and conditions — context for your own decisions, not instructions to trade.
