Call Option

The right to buy at a set price: leveraged upside with loss capped at the premium.

Quick answer

A call option is the right to buy at a set strike before expiry. Buyers get leveraged upside with losses capped at the premium paid.

Definition

A call option gives the holder the right, never the obligation, to buy an asset at the strike price before expiry. Buyers profit when price rallies past strike plus premium; maximum loss is the premium. Sellers collect that premium and carry theoretically uncapped risk on naked calls.

How It Works

  • Gains value as price rises above strike
  • Buyer loss capped at premium, seller risk open
  • Value splits into intrinsic plus time value

Trading Tips

1

Buy calls with enough expiry for the thesis to develop

2

Avoid weekly options unless scalping defined events

3

Selling naked calls is professional territory only

Call Option Example

Say shares trade $100 and you buy a $105 call for $3 instead of 100 shares for $10,000. Stock hits $115 and the call returns over 200% on $300 risked. Stock flat at $101 costs the full $300: leverage with a receipt.

How Traders Use Call Option

Use calls for high-conviction breakouts where shares tie too much capital. Give trades room with further-dated expiry, and never allocate more premium than a full loss allows.
