What is the maximum loss on a long call?

The maximum loss on a long call is the premium you paid for the option, and no more. It occurs if the option expires at or below the strike price.

When should you buy a call option?

A long call suits a strongly bullish view where you expect a meaningful up-move before expiry and want limited, defined risk. It is sensitive to time decay and falling implied volatility, so timing matters.

Long Call
Strategy

The simplest bullish trade in options: buy a call, risk only the premium, and profit if the underlying rises. Here's exactly how it works, with the numbers.

What it is

A long call means buying a single call option. You pay a premium today for the right (not the obligation) to buy the underlying at the strike price until expiry. It's the most direct way to express a bullish view with strictly limited risk.

Key facts

Market view: bullish (expect a decent up-move).
Construction: Buy 1 call (usually ATM or slightly OTM).
Net cost: debit — you pay the premium.
Max profit: theoretically unlimited as the underlying rises.
Max loss: limited to the premium paid.
Breakeven: strike price + premium paid.

How to construct it

Pick an expiry that gives your view enough time to play out.
Choose a strike — ATM for balance, slightly OTM for cheaper cost and higher leverage.
Buy 1 call at that strike. The premium is your total risk.

Worked NIFTY example

Suppose NIFTY is at 22,500 and you buy the 22,500 call for a premium of 150 (illustrative):

Breakeven: 22,500 + 150 = 22,650.
If NIFTY expires at 22,900 → call worth 400 → profit = 400 − 150 = 250 per unit.
If NIFTY expires at or below 22,500 → call expires worthless → loss = 150 (the premium), and nothing more.

When to use it

You have a strong directional bullish view with a catalyst or timeframe in mind.
You want defined, limited risk rather than the open risk of futures.
Implied volatility is not extremely high (so you're not overpaying for the option).

Risks to respect

Time decay (theta): the option loses value each day if price doesn't move.
IV crush: a drop in implied volatility can shrink your premium even if price holds.
You need the move to be big enough and fast enough to clear the breakeven.
