What happens when a stock price rises above the strike price?
When a stock’s market price rises above the strike price, a put option is out of the money. This means that, other than the premium, the option has no value and the price is close to nothing.

When should you sell options?

What is the price of a 2,000 share bid on Radioshack?
If a MM is bidding $20.04 for 2,000 shares of RadioShack Corp., it is obligated to buy 2,000 shares of RSH at the $20.04 bid price. However, if a 1,000-share sell order is filled at the 20.04 price, the MM may raise or lower the bid if there are no market orders for RSH at that time. If there are other market orders, they must be filled and the entire 2,000 share quote-width bought before the MM can revise the quotations.
What is a tick in stock?
The tick (minimum price variation) is the smallest unit price change allowed in trading a security. For stocks, the minimum tick is a penny, or less. Until 2001, stock prices were quoted under the old fractionalization scheme – eighths and quarters. This resulted in huge spreads that really picked the pockets of traders and investors. That year the SEC forced decimalization down the financial industry’s throat – quoting prices in pennies, essentially, getting rid of the fractions. Decimalization has resulted in much narrower bid-asked spreads, among many other benefits.
What is the tick price for an option?
For a listed option under $3 in price, the tick currently is $0.05 and for a listed option over $3 in price, it is generally $0.10. Thus if an option premium is less than $3.00, the ticks can be in nickels or dimes, but if over $3.00 the ticks will always be in dimes. This is fractionalization in twentieths and tenths and it, too, is changing. Penny pricing (0.01 tick increments) for stock options exists for certain stocks and is the norm on highly liquid options due to their popularity.
How much should a spread be on an option?
Beware of buying or selling any option when the spread is greater than $0.30. Since most retail traders sell at the bid and pay the ask, large spreads pick their pockets. If an option is quoted 1.00 x 1.30, for example, a buyer likely would pay $1.30, but selling it upon a change of heart a few minutes later at the same quotes, would only receive the $1.00 bid – a $0.30 loss (23%) due solely to the large spread. A liquid option in this price range should have a spread of $0.10 to $0.15 at most.
What is the standard quote width for options?
The quote width varies by exchange (including Nasdaq), but the standard for option exchanges is 10 contracts (known as 10-up). See for example, CBOE Rule 8.7 (d) (ii).

In other words, to calculate how much of an option's premium is due to intrinsic value, an investor would subtract the strike price from the current stock price.

The rate at which a stock price fluctuates is called volatility .

Why do investors pay premiums on options?
Investors are willing to pay a premium for an option if it has time remaining until expiration because there's more time to earn a profit. The longer the time remaining, the higher the premium since investors are willing to pay for that extra time for the contract to become profitable or have intrinsic value.

Understanding The Basics of Option Prices
Intrinsic Value
- One of the key drivers for an option's premium is the intrinsic value. Intrinsic value is how much of the premium is made up of the price difference between the current stock price and the strike price. For example, let's say an investor owns a call option on a stock that is currently trading at $49 per share. The strike price of the option is $45,...
Time Value
- The time remaining until an option's expiration has a monetary value associated with it, which is known as time value. The more time that remains before the option's expiry, the more time value is embedded in the option's premium. In other words, time value is the portion of the premium above the intrinsic value that an option buyer pays for the privilege of owning the contract for a c…
Time Value and Volatility
- The rate at which a stock's price fluctuates, called volatility, also plays a role in the probability of an option expiring in the money. Implied volatility, also known as vega, can inflate the option premium if traders expect volatility. Implied volatility is a measure of the market's view of the probability of stock's price changing in value. High volatility increases the chance of a stock mov…
The Bottom Line
- An option's value or premium is determined by intrinsic and extrinsic value. Intrinsic value is the moneynessof the option, while extrinsic value has more components. Before booking an options trade, consider the variables in play and have an entry and exit strategy.
Option Pricing Models
The Black-Scholes Formula
- The Black-Scholes model is perhaps the best-known options pricing method. The model's formula is derived by multiplying the stock price by the cumulative standard normal probability distribution function. Thereafter, the net present value (NPV) of the strike price multiplied by the cumulative standard normal distributionis subtracted from the resulting value of the previous calculation. I…
Intrinsic Value
- Intrinsic value is the value any given option would have if it were exercised today. Basically, the intrinsic value is the amount by which the strike price of an option is profitable or in-the-money as compared to the stock's price in the market. If the strike price of the option is not profitable as compared to the price of the stock, the option is said to be out-of-the-money. If the strike price i…
Time Value
- Since options contracts have a finite amount of time before they expire, the amount of time remaining has a monetary value associated with it—called time value. It is directly related to how much time an option has until it expires, as well as the volatility, or fluctuations, in the stock's price. The more time an option has until it expires, the greater the chance it will end up in the mo…
Volatility
- An option's time value is also highly dependent on the volatility the market expects the stock to display up to expiration. Typically, stocks with high volatility have a higher probability for the option to be profitable or in-the-money by expiry. As a result, the time value—as a component of the option's premium—is typically higher to compensate for the increased chance that the stock'…
Examples of How Options Are Priced
- Below, you can see the GE example already discussed. It shows the trading price of GE, several strike prices, and the intrinsic and time values for the call and put options.

The table below contains the pricing for both calls and puts that are expiring in one mo…
