For example, suppose a put option with a strike price of $100 for ABC stock is sold at $1.00 and a put option for ABC with a strike price of $90 is purchased for $0.50, and at the option's expiration the price of the stock or index is greater than the short put strike price of $100, then the return generated for this position is:
Major online brokers don’t charge for stock and ETF trades, and many offer thousands of no-transaction-fee mutual funds, too. But options still routinely cost about $0.65 per contract, though ...

More specifically, TV reflects the probability that the option will gain in IV — become (more) profitable to exercise before it expires. [6] An important factor is the underlying instrument's volatility ...

Time value is the amount the option trader is paying for a contract above its intrinsic value, with the belief that prior to expiration the contract value will increase because of a favourable change in the price of the underlying asset.
In the above formulae: is the length of time per step in the tree and is simply time to maturity divided by the number of time steps; is the risk-free interest rate over this maturity; is the corresponding volatility of the underlying; is its corresponding dividend yield.
If a company grants options on June 1 (when the stock price is $100), but backdates the options to May 15 (when the price was $80) in order to make the option grants more favorable to the grantees, the fact remains that the grants were actually made on June 1, and if the exercise price of the granted options is $80, not $100, it is below fair ...
Suppose the current stock price of IBM is $100. A call or put option with a strike of $100 is at-the-money. A call with a strike of $80 is in-the-money (100 − 80 = 20 > 0). A put option with a strike at $80 is out-of-the-money (80 − 100 = −20 < 0). Conversely, a call option with a $120 strike is out-of-the-money and a put option with a ...
