Options Calls vs Puts: What Traders Must Understand Before Taking a Position

Call options give the buyer the right to buy an asset at a fixed strike price, while put options give the buyer the right to sell an asset at a fixed strike price. Calls usually benefit from bullish moves, while puts usually benefit from bearish moves.

What are call and put options?

Options are contracts linked to an underlying asset like a stock, ETF, or index.

Call option

A call gives the buyer the right, but not the obligation, to buy the underlying asset at the strike price before or at expiration.

Put option

A put gives the buyer the right, but not the obligation, to sell the underlying asset at the strike price before or at expiration.

How does a call option work with an example?

Example from your research:

• stock price = $50
• you buy a $55 call for $0.20
• stock goes to $60

Now that call lets you buy at $55 while market is at $60.

Gross value = $5.00
Net profit = $5.00 − $0.20 = $4.80 per share

If stock stays below $55, the option may expire worthless and the buyer loses the premium.

How does a put option work with an example?

Example from your research:

• stock price = $50
• you buy a $45 put for $0.20
• stock falls to $40

Now that put lets you sell at $45 while market is at $40.

Gross value = $5.00
Net profit = $5.00 − $0.20 = $4.80 per share

If stock stays above $45, the put may expire worthless and the buyer loses the premium.

Naked put

You may not have adequate cash or risk preparation.

General situations:

• when you expect limited upside

You own shares and sell calls to collect premium. This is usually more conservative than naked call writing.
