Understanding and Analyzing Risk & Reward with a Stock Option Calculator
The risk of an equity option trade is measured by its maximum loss, breakeven price, and sensitivity to price, volatility, and time (the Greeks). A buyer can lose at most the premium paid; a seller of an uncovered option can lose far more than the premium received. A stock option calculator in Excel computes the theoretical premium (Black-Scholes or binomial), the profit and loss at expiration, and the breakeven, so you can see the risk before placing the trade.
What are Stock Options
Stock options are contracts that give the buyer the right, but not the obligation to buy or sell shares of an underlying stock at a pre-determined price on a determined date in the future. Generally, an investor buys a stock option to hedge their risks and maximize returns. Buying options requires less capital than buying the shares outright, but the premium can be lost entirely, and selling options can create losses larger than the premium received.
Option Pricing
Option pricing estimates the fair value (premium) of an option from the underlying stock price, strike price, time to expiration, implied volatility, and interest rates. The Option Premium calculator can help you find out the Black-Scholes target premium of a call and put options with a few simple inputs.
Option Analysis
Option Analysis plays a vital role in understanding and analyzing the risks associated with trading equity options.This involves calculating profit and loss of a trade, taking into account factors such as the cost to purchase the option, any commissions paid and implicit fees. The Binomial Option Pricing Model Excel helps you determine theoretical option prices and the associated risks of the trade by using inputs such as the values ofstrike price, expiration date, current stock price and associated dividends.
Retirement Planning & Financial Planning
Some investors use options within retirement and financial planning, for example to hedge a portfolio or generate income. Future performance is difficult to predict. Proper understanding of volatility and other associated risks can help manage portfolio risk and make better investment decisions.
