Call Options

Introduction

A call option is the simplest way to profit from a rising stock or index using less capital. In this lesson, you will learn how call options work with clear rupee examples and how swing traders use them.

What is a Call Option?

A call option gives the buyer the right, but not the obligation, to buy the underlying at the strike price on or before expiry. You buy a call when you expect the price to go up.

How a Call Option Makes Money

When the underlying price rises, the call premium usually rises too. You can sell the call at the higher premium and keep the difference.

Example 1: Profitable Call Trade

HIJ Ltd trades at Rs 1,000. A buy setup forms at support. The 1,000 strike call costs Rs 25. Assume lot size 500.

• Cost: 25 x 500 = Rs 12,500. (Buying 500 shares would need Rs 5,00,000.)
• In 5 days, HIJ rises to Rs 1,040. The call premium rises to about Rs 50.
• Sell the call. Profit = (50 - 25) x 500 = Rs 12,500. That is a 100% return on premium.
• Shareholders with 500 shares would have made Rs 20,000 but with Rs 5,00,000 invested, a 4% return.

Example 2: Losing Call Trade

Instead, HIJ falls to Rs 975 over a week. The call premium falls to Rs 8.

• Loss = (25 - 8) x 500 = Rs 8,500.
• If you had held until expiry with HIJ below Rs 1,000, the call would expire worthless and you would lose the full Rs 12,500.

Example 3: Right Direction, Small Move

HIJ rises only to Rs 1,010 slowly over two weeks. Time decay reduces the premium. The call may be worth about Rs 20. You lose Rs 5 per unit even though you were right on direction. Options need a meaningful move in a reasonable time.

Breakeven at Expiry

Breakeven = Strike + Premium. For the 1,000 call bought at Rs 25, the stock must be above Rs 1,025 on expiry to profit if held till the end. Swing traders usually exit earlier.

Choosing the Right Call

• Strike: ATM or slightly ITM for beginners. Cheap far OTM calls usually expire worthless.
• Expiry: choose one with at least 2 to 3 weeks left so time decay is slower.
• Liquidity: trade options with good volume and small bid-ask spreads.

When to Buy Calls

• A confirmed buy setup at support.
• A breakout above resistance with strong volume.
• The overall market (Nifty) supports the direction.

When to Exit

• The stock reaches your chart target.
• The stock breaks your chart stop-loss level.
• The premium falls 30% to 40% from your buy price.

Frequently Asked Questions

Do I need to buy the shares at expiry?

No. Most traders sell the call before expiry. In-the-money stock options held to expiry may be physically settled, so exit before expiry to avoid delivery obligations.

Why did my call lose value when the stock was flat?

Time decay. Options lose value every day.

Key Takeaways

• Buy calls when you expect a rise.
• Maximum loss is the premium paid.
• You need a strong enough move in enough time.
