The four basic option positions

There are exactly four single-leg option positions: buy a call, buy a put, sell a call, sell a put. Buyers pay and have a capped loss. Sellers collect and have a capped gain. Every strategy with a name is a combination of these four, and two of them are all a premium seller ever needs.

Two contracts, two directions, four positions. Everything else on this site, and every structure with a Greek or an animal in its name, is built from them.

All four at once

DKNG at $38.40, September 19, 45 days. One strike, $40, so the comparison is clean. The call is $1.38 and the put is $2.78, both at the mid.

Read across a row and the two sides sum to zero, every time. Options are a transfer, not a creation. Read down a column and you get the shape of each position.

The two you buy

Long call. Pay $138, and below $40 that is the whole story: the contract expires and the money is gone. Above $41.38 you make money and it keeps going. Maximum loss $138, maximum gain unbounded, and roughly a 36.6 percent chance of finishing in the money at all. This is the trade almost everybody starts with and the reason most people's first year in options goes badly.

Long put. Pay $278, profit as the stock falls, capped at $3,722 if DKNG goes to zero. Bought on its own it is a bet on a decline. Bought against shares you own it is insurance, and it costs 7.2 percent of the position for 45 days of cover, which is why nobody hedges continuously.

The two you sell

Short put. Collect $278. Your best case is exactly that, reached anywhere at or above $40. Your worst case is $3,722, reached at zero. This is the cash-secured put once you park $4,000 against it, and it is the trade cluster E takes apart end to end.

Short call. Collect $138. Best case $138. Worst case has no number in it. At $52 you are down $1,062 and the row below the table does not exist because there is nothing to put in it. Naked, this is the position that ends accounts, and it ends them on takeover announcements and squeezes rather than on slow drifts.

Own 100 shares first and it becomes a covered call, where the unbounded loss becomes an unbounded opportunity cost. Those are extremely different things, and the difference is the shares.

The shape, in one sentence each

• Long call: small known cost, large unknown gain, needs the stock to move.
• Long put: small known cost, large capped gain, needs the stock to fall.
• Short call: small known gain, unbounded loss, wants nothing to happen.
• Short put: small known gain, large capped loss, wants nothing to happen.

The buyers need a move and pay for the privilege of waiting. The sellers need stillness and get paid for the risk that it does not arrive. That is the whole of it, and the Greeks are just the same statement in calculus.

Why the numbers are not symmetric

The put costs $278 and the call costs $138, at the same strike, on the same stock. Twice as much.

Partly because $40 is $1.60 above the stock, so the put is already in the money and carries $1.60 of intrinsic value. Strip that out and you get $1.18 of time value against the call's $1.38, and that remaining 20 cent gap is the interest on the strike. Partly because the put side carries higher implied volatility at every strike, which is skew.

Which is why sellers who can choose tend to end up on the put side, and why the choice is really a question about what you want to be left holding.

What a premium seller actually uses

Two of the four, and never bare.

Short call plus 100 shares is a covered call. Short put plus the cash is a cash-secured put. Do them in sequence on the same ticker and you are running the wheel. That is the entire strategy family this site is built around, and it is three trades made of two positions.

The other combinations are worth knowing about. Buying a further option against the one you sold caps the loss and creates a credit spread, which is how you sell premium without owning the shares or securing the cash. That trades an obligation you can meet for one that is simply smaller.

OptionsKing scores every candidate strike on a deterministic 0 to 100 scale, blends that score with the return on the capital the trade ties up, and shows you the highest-ranked handful. There is no minimum score. How it works covers what the ranking does and does not tell you.
