What is an Option - Part 2

...continued from Part 1

LEVERAGE AND RISK
Options can provide leverage. This means an option buyer can pay a relatively small premium for market exposure in relation to the contract value (usually 100 shares of the underlying stock). An investor can see large percentage gains from comparatively small, favorable percentage moves in the underlying index.

Leverage also has downside implications. If the underlying stock price does not rise or fall as anticipated during the lifetime of the option, leverage can magnify the investment's percentage loss. Options offer their owners a predetermined, set risk. However, if the owner's options expire with no value, this loss can be the entire amount of the premium paid for the option. An uncovered option writer, on the other hand, may face unlimited risk.

IN-THE-MONEY, AT-THE-MONEY, OUT-OF-THE-MONEY...
The strike price, or exercise price, of an option determines whether that contract is in-the- money, at-the-money, or out-of-the-money. If the strike price of a call option is less than the current market price of the underlying security, the call is said to be in-the-money because the holder of this call has the right to buy the stock at a price which is less than the price he would have to pay to buy the stock in the stock market.

Likewise, if a put option has a strike price that is greater than the current market price of the underlying security, it is also said to be in-the-money because the holder of this put has the right to sell the stock at a price which is greater than the price he would receive selling the stock in the stock market. The converse of in-the-money is, not surprisingly, out-of-the-money. If the strike price equals the current market price, the option is said to be at-the-money.

The amount by which an option, call or put, is in-the-money at any given moment is called its intrinsic value. Thus, by definition, an at-the-money or out-of-the-money option has no intrinsic value; the time value is the total option premium. This does not mean, however, these options can be obtained at no cost. Any amount by which an option's total premium exceeds intrinsic value is called the time value portion of the premium.

It is the time value portion of an option's premium that is affected by fluctuations in volatility, interest rates, dividend amounts, and the passage of time. There are other factors that give options value and therefore affect the premium at which they are traded. Together, all of these factors determine time value.

EQUITY CALL OPTION:
In-the-money = strike price less than stock price
At-the-money = strike price same as stock price
Out-of-the-money = strike price greater than stock price

EQUITY PUT OPTION:
In-the-money = strike price greater than stock price
At-the-money = strike price same as stock price
Out-of-the-money = strike price less than stock price

OPTION PREMIUM
Intrinsic Value + Time Value

TIME DECAY
Generally, the longer the time remaining until an option's expiration, the higher its premium will be. This is because the longer an option's lifetime, greater is the possibility that the underlying share price might move so as to make the option in-the-money. All other factors affecting an option's price remaining the same, the time value portion of an option's premium will decrease (or decay) with the passage of time.
