Long Call (Buying a Call)

A long call is a bullish strategy used when an investor expects the stock price to rise.

Example

Buy 1 XYZ 50 Call @ $3

CalculationFormulaResult
Maximum GainUnlimitedStock can rise infinitely
Maximum LossPremium paid$3 × 100 = $300
BreakevenStrike + Premium$50 + $3 = $53

The investor profits when the stock rises above $53. Below $50, the option expires worthless and they lose the $300 premium.

Short Call (Writing a Call)

A short call is a bearish to neutral strategy. The writer receives premium but takes on the obligation to sell shares if assigned.

Example

Sell 1 XYZ 50 Call @ $3

CalculationFormulaResult
Maximum GainPremium received$3 × 100 = $300
Maximum LossUnlimitedStock can rise infinitely
BreakevenStrike + Premium$50 + $3 = $53

Warning: Uncovered (naked) calls have unlimited risk because the stock can rise indefinitely and the writer must purchase shares at market price to deliver.

Long Put (Buying a Put)

A long put is a bearish strategy used when an investor expects the stock price to decline.

Example

Buy 1 XYZ 50 Put @ $4

CalculationFormulaResult
Maximum GainStrike - Premium($50 - $4) × 100 = $4,600
Maximum LossPremium paid$4 × 100 = $400
BreakevenStrike - Premium$50 - $4 = $46

The investor profits when the stock falls below $46. Maximum gain occurs if the stock goes to zero (the investor can sell worthless stock for $50).

Short Put (Writing a Put)

A short put is a bullish to neutral strategy. The writer receives premium but takes on the obligation to buy shares if assigned.

Example

Sell 1 XYZ 50 Put @ $4

CalculationFormulaResult
Maximum GainPremium received$4 × 100 = $400
Maximum LossStrike - Premium($50 - $4) × 100 = $4,600
BreakevenStrike - Premium$50 - $4 = $46

Exam Tip: Short put writers may be required to purchase stock at the strike price even if it falls to zero.
