Options Basics
Calls vs Puts
Understand how call and put rights, obligations and directional exposure differ. Includes a worked example, risks and primary sources.
A call option gives its buyer the right to buy the underlying at the strike price, while a put gives its buyer the right to sell. Call buyers generally benefit from rising prices; put buyers generally benefit from falling prices. Sellers take the opposite contractual obligation if assigned.

Definition and mechanics
The option type and whether it is bought or sold must be read together. A long call and short put can both express bullish exposure, but their payoff, capital needs and assignment consequences are different.
How to evaluate it
Read the option type together with the transaction side. A long call, short call, long put and short put create different rights, obligations and payoff boundaries. Compare premium, breakeven, capital required, time decay, volatility exposure and assignment consequences instead of treating every call as bullish or every put as bearish.
Worked example
With shares at $100, a $105 call gains intrinsic value above $105, while a $95 put gains intrinsic value below $95. Premium paid or received changes the position breakeven.
Risks and limitations
- Direction alone does not determine profit: time decay, volatility changes and the premium paid or received also matter.
- Options involve risk and can lose part or all of the capital committed. Multi-leg positions also introduce execution, assignment and management complexity.
Common misconception
Reality check
A put is not always bearish and a call is not always bullish; selling changes the exposure and obligation.
