Expert Tip

A cash-secured put involves selling a put option while holding cash collateral to buy the stock if assigned at the strike price.

How this Calculator Works

Subtracts premium from the strike to find the net stock cost, and determines cash returns relative to collateral requirements.

Formula & Methodology

Collateral = (Strike - Premium) * 100 Yield % = (Premium / (Strike - Premium)) * 100 Effective Purchase = Strike - Premium

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

If Stock = $80.00, Strike = $75.00, Premium = $2.50: - Collateral = ($75.00 - $2.50) * 100 = $7,250.00 - Yield = ($2.50 / $72.50) * 100 = 3.45% - Effective Purchase Price = $72.50

FAQ

What are the primary Option Greeks and what do they measure?
Delta (ฮ”) measures price sensitivity to underlying asset moves; Gamma (ฮ“) measures rate of Delta change; Theta (ฮ˜) measures daily time decay; Vega (ฮฝ) measures sensitivity to 1% volatility changes.
What is Put-Call Parity?
Put-Call Parity defines the static equilibrium relationship: Call Price - Put Price = Spot Price - Present Value of Strike Price. It prevents arbitrage between options and European spot markets.
Can option pricing models guarantee trading profits?
No. Black-Scholes and Binomial models assume continuous trading, constant volatility, and lognormal price distributions. Options trading involves substantial risk of capital loss due to leverage and volatility expansion.
