The long call
A long call is a bet the underlying rises enough, soon enough. Maximum loss is the premium, breakeven is strike plus premium, and gain above it is open-ended. It loses if the move is too small, too slow, or bought at high volatility.
- Explain the view, payoff, and breakeven of a long call
- State the maximum loss and how the position really loses
- Choose a sensible strike and expiry as a beginner
This is the trade most beginners meet first, and the simplest way to act on a bullish view with options: buy a call. You have now met every piece of it. This chapter assembles them into one real position, with its view, its payoff, its breakeven, and, just as important, the honest ways it loses.
The view
You buy a call when you expect the underlying to rise, and to rise meaningfully and reasonably soon. A long call is not a vague bet that a stock is good. It is a bet that the price will climb past a particular level within a particular window of time, before decay and expiry catch up with you. Direction, size of move, and timing all matter.
The payoff, in one place
The shape is the one from the payoff chapter. Your maximum loss is the premium you paid, and no more, however far the stock falls. Your breakeven is the strike plus the premium, because you must earn back what you paid before you profit. Above breakeven, the gain rises with the price, with no fixed ceiling.
| Infosys at expiry | Outcome per share on a 1,520 call bought for 20 |
|---|---|
| 1,500 or below | lose 20 (the premium) |
| 1,520 | lose 20 |
| 1,540 | breakeven |
| 1,600 | profit 60 |
Multiply by the lot size for the real rupees, and remember that the per-lot premium is your true maximum loss.
Why buy a call instead of the shares
The appeal is the shape from the very first chapters: a small, fixed, known risk in exchange for a large potential gain. For the price of the premium you take on the upside of a much larger position, and your downside is capped at that premium, whatever happens. The trade-off is real. Unlike shares, which rarely fall to zero and never expire, a call can lose its entire value, and it does so on a deadline, worn down by time every day you hold it.
How a long call really loses
Being right on direction is necessary but not enough, as the last two parts showed. A long call loses in three honest ways. The stock may simply not move enough, and finish below the strike, so the call expires worthless and you lose the whole premium. The stock may move your way but too slowly, so time decay drains the option faster than the move builds it. Or you may have bought when implied volatility was high, ahead of an event, and been caught by the volatility crush when it passed. Enough move, fast enough, without overpaying: all three have to line up.
A sensible beginner default is a call that is at-the-money or only slightly out-of-the-money, with enough time for the thesis to play out. The cheap, far out-of-the-money, near-expiry call is the lottery ticket the earlier chapters warned about: it looks affordable and usually expires worthless. Buying enough time is not a luxury here, it is protection against the clock.
What to carry forward
A long call expresses a bullish view with a small, capped, known risk, the premium, and an open-ended potential gain above a breakeven of strike plus premium. Its honesty lies in how it loses: the stock must move far enough and fast enough, without you overpaying for volatility, so being merely right on direction is not enough. Chosen with enough time and sized by its per-lot cost, it is the natural first options trade, which is exactly why it is worth rehearsing before risking real money.
The mirror image comes next, the trade for a fall and for protection: the long put.
