What happens to a put option if the stock goes up?
But if the stock price goes up to $45 per share, exercising the option only nets you $5 per share. In other words, when the stock price goes up, the price of a put option goes down. When a stock’s market price rises above the strike price, a put option is out of the money.
What happens if you exercise an option to buy more shares?
If you exercise this option, you have to pay a strike price to buy the shares that is more than the market price, so you can’t make a profit by selling the stock at market. This remains true as long as the stock price stays below the strike price.
How much can you make by exercising a $25 stock option?
If the strike price is $25 and the stock goes up to $30, you can make $5 per share by exercising the option – so $5 plus the premium is the price of the option. If the stock keeps going up to $35, that’s $10 per share more than the strike price.
What drives the price of an option?
Let's start with the primary drivers of the price of an option: current stock price, intrinsic value, time to expiration or time value, and volatility. The current stock price is fairly straightforward.
How does option price change with stock price?
The current stock price is fairly straightforward. The movement of the price of the stock up or down has a direct, though not equal, effect on the price of the option. As the price of a stock rises, the more likely it is that the price of a call option will rise and the price of a put option will fall.
Why did my option price change?
Like most other financial assets, options prices are influenced by prevailing interest rates, and are impacted by interest rate changes. Call option and put option premiums are impacted inversely as interest rates change: calls benefit from rising rates while puts lose value.

Why did my call option go up when the stock went down?
As interest rates rise, call option premiums increase. Higher rates increase the underlying stock's forward price (the stock price plus the risk-free interest rate). If the stock's forward price increases, the stock gets closer to your strike price, which we know from above helps increase the value of your call option.
How much does an option go up when the stock goes up?
In-the-Money Calls The call option is now “in the money” and the more the stock price goes up, the more the price of the option rises. If the strike price is $25 and the stock goes up to $30, you can make $5 per share by exercising the option – so $5 plus the premium is the price of the option.

How option prices are determined?
Options prices, known as premiums, are composed of the sum of its intrinsic and time value. Intrinsic value is the price difference between the current stock price and the strike price. An option's time value or extrinsic value of an option is the amount of premium above its intrinsic value.
What are the 6 determinants of option values?
There are primarily six factors that determine the value of an option. The factors are underlying price, exercise price, time to expiration, risk-free rate, volatility, and interim cash flows & costs.
Why do options prices change overnight?

Do options move stock prices?
Options do not impact stock prices. It is the opposite, the derivative affect of the underlying on the resulting value of the option.
How much value does an option lose per day?
Theta is the Greek that reports how much an option theoretically decreases in value with the passing of each day. For example, if you purchase a call option for $5 and the theta of the option is $0.50, then it will theoretically lose $0.50 of value for each day that passes.
Do options prices change at market open?
That is patently false. The opening price for a security is set by an auction in which buyers and sellers submit limit orders prior to the market open. The opening price will be a price at which the greatest volume will be executed according to those submitted orders.
Why is my put option going down?
Time Decay Simply put, every day, your option premium is losing money. This results in the phenomenon known as Time Decay. It should be noted that only the premium portion of the option is subject to time decay, and it decays faster the closer you get to expiration.

Why is my option price not moving?
The price movement occurs only if there is trading activity in a stock or a contract. If there is no price movement for the option you are looking at, that means there is no trading activity. To check the trading activity of any given instrument, it is important to check the Last Traded Time (LTT) .

How does time value relate to options?
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.
What is historical volatility?
Historical volatility (HV) helps you determine the possible magnitude of future moves of the underlying stock. Statistically, two-thirds of all occurrences of a stock price will happen within plus or minus one standard deviation of the stock's move over a set time period.
What is the most widely used model of options?
Of these, the Black-Scholes model is the most widely known. 1 In many ways, options are just like any other investment—you need to understand what determines their price to use them effectively. Other models are also commonly used, such as the binomial model and trinomial model .
How does time decay in an option?
The time component of an option decays exponentially. The actual derivation of the time value of an option is a fairly complex equation. As a general rule, an option will lose one-third of its value during the first half of its life and two-thirds during the second half of its life.
What does a positive delta mean in a call option?
Positive delta represents an increase in the option price when the stock price rises, and a decrease in the option price when the stock price falls. The following visual demonstrates how call option’s with varying deltas are more or less sensitive to changes in the stock price:
Do options have a single price?
Options, futures, and stocks don't have a single price: they have two prices, the bid and the ask. Both prices are provided by a market maker: the bid is the last price a market maker bought shares at, and the ask is the last price a market maker sold shares at. When the market maker buys or sells, the most recent price is called the tick, and it is either a downtick or an uptick, respectively. That tick is the “price” reported.
How do put options work?
Put options work in reverse to call options. A put option is in the money when the market price is less than the strike price. This is because you can buy the shares on the market and sell them to the option writer, who has to pay you the higher strike price.

Understanding The Basics of Option Prices
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. At the time of this writing, General Electric was considered a stock with low volatility and had a beta of 0.49 for this example. The table below contains the pricing for both calls and puts that are expiring in one mo…
