Bull Call (debit)

Spreads2 legsdebitbullish

Buy a call and sell a further-out one above it. A directional bullish bet with a known cost and a known ceiling — cheaper than the call alone, and capped.

What it is

You buy the call you want and sell a further one to help pay for it. The debit is what you can lose, in total, whatever happens.

This is a debit structure, so time works against it: both legs decay, and the long one you paid for decays faster in the region that matters. The stock has to move for it to pay.

Selling the upper call cuts the cost substantially and caps the upside. Whether that is a good trade depends entirely on whether you expected the stock to travel past the short strike.

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: $160 — the gross amount tied up, before the premium received.

A $50 call bought for $2.80 with a $55 call sold for $1.20 — a $1.60 net debit on a $5-wide spread. The short call pays for 43% of the long call's cost and caps the gain at $55. Maximum loss is the debit, and nothing more.

Reading the shape

Flat at the maximum loss below the long strike — the debit, and nothing worse.

Rising between the strikes, then flat at maximum profit above the short strike: the width minus the debit.

One break-even, at the long strike plus the debit.

How it is used

This is a directional position rather than an income one. It suits a specific view on a specific move within a specific window, which is a different kind of judgment from selling premium.

Low implied volatility favours a buyer, the opposite of every credit structure in this menu: you are paying for optionality, so paying less for it matters.

Because the risk is the debit and nothing more, position sizing is unusually simple — the most you can lose is what you paid.

The short leg's strike is a statement about where you think the move stops. If you have no view on that, the structure is arbitrary — and the naked long call may be the honest expression of the idea.
Time is against you. A credit structure profits from nothing happening; this one loses to it.
Being right about direction and wrong about timing loses the whole debit. The option expires on a date whether the thesis plays out by then or not.
