HOW IT WORKS

How a long call works

A long call gives you the right, but not the obligation, to buy 100 shares at the strike price any time before expiry. You pay a premium for that right, and the premium is the entire amount you can lose. That fixed downside is the reason traders reach for calls instead of buying stock outright: a $250 call controls the same 100 shares as a $10,000 stock position, and the worst case is $250.

The trade-off is that you are paying for time, and time runs out. A call has intrinsic value only when the stock trades above the strike; everything above that is extrinsic value, which decays toward zero as expiry approaches. This decay — theta — accelerates in the final weeks. A stock that drifts sideways at your strike will still lose you money, which is not true of owning the shares.

Breakeven is the strike plus the premium you paid, because you have to recover the cost of the option before the position turns positive. This is why a call can be directionally right and financially wrong: the stock rises, but not far enough or not fast enough to clear the premium before expiry.

WORKED EXAMPLE

A worked example

XYZ trades at $100. You expect a move higher over the next two months and buy one $105 call expiring in 60 days for a premium of $2.50 per share.

Debit paid
$2.50 × 100 = $250 (max loss)
Breakeven
$105 strike + $2.50 = $107.50
At expiry, XYZ = $115
Intrinsic $10.00 × 100 = $1,000 − $250 debit = +$750
At expiry, XYZ = $107.50
Intrinsic $2.50 × 100 = $250 − $250 = $0, breakeven
At expiry, XYZ ≤ $105
Expires worthless, −$250

The stock rising 7.5% only gets you to breakeven. It has to clear $107.50 before the position makes anything — the premium is a hurdle, not a deposit.

FIT

When a long call fits — and when it doesn't

Consider it when
  • You have a directional view with a timeframe attached, not just "this goes up eventually".
  • You want defined risk on a volatile or expensive underlying where a stock stop could gap through.
  • Implied volatility is low relative to its own recent range, so you are not overpaying for extrinsic value.
Think twice when
  • Implied volatility is elevated ahead of a known event — you can be right on direction and still lose to the IV crush after the print.
  • Your thesis has no deadline. Time decay charges you rent for a view that has not got a date on it.
  • The premium is a large share of the move you are actually forecasting.
FAQ

Common questions

What is the maximum I can lose on a long call?

The premium paid, and nothing more. One contract bought at $2.50 per share costs $250, and $250 is the worst case even if the stock goes to zero.

How is the breakeven on a long call calculated?

Strike price + premium paid per share. A $105 call bought for $2.50 breaks even at $107.50 at expiry. Before expiry the position can be profitable below that, because the option still carries extrinsic value.

Why did my call lose money when the stock went up?

Usually one of two reasons. Either time decay removed more extrinsic value than the move added, or implied volatility fell — commonly right after an earnings report — and repriced the option downward despite the favourable move.

Should I exercise a profitable call or sell it?

Selling is almost always the better mechanic. Exercising captures only intrinsic value and discards any remaining extrinsic value, and it requires the capital to actually buy 100 shares per contract.
