Just as there are two different types of options puts and callsso there are two main styles of options: American and European. These options have many similar characteristics, but it's the differences that are important. Many rookies have suffered unnecessary losses because they were unaware of the differences. In this article, we'll discuss these differences and how they affect you, so you can discover how american call option vs european put option and call avoid potentially costly problems.

Differences There are four key differences between American- and European-style options: Exercise Rights When you own an option, you control the right to exercise. Occasionally, it may be beneficial to exercise an option before it expires to collect a dividendfor examplebut it's seldom important. When you are short an American-style option you sold the option without owning it and are assigned an exercise notice before expiration, instead of being short the option, you are now short the stock.

Unless your account is too small to carry a short stock position, this is not a problem; and if your account is that small, you should probably not be trading options. The only time an early assignment carries any significant risk occurs with American-style, cash-settled index options. So the easiest way to avoid the early-exercise risk is to avoid trading American options. When you receive an assignment notice in the morning, you must repurchase that option at the previous night's intrinsic value.

That may place you at serious risk if the market undergoes a significant move, because that forced purchase makes your position different from the one you thought you owned. Cash Settlement It's advantageous to everyone when options are settled in cash: Because these cash-settled options are almost always European-style, and assignment only occurs at expiration, the option's cash value is determined by the settlement price.

Settlement Price With American-style options, there are seldom any surprises. If you have a short position in the 40 call and don't want to be assigned an exercise notice, you can repurchase those calls. The settlement price may change, and those 40 calls may move out of the money, but it's unlikely that the value of those calls will change significantly in the last few minutes.

With European-style options, the settlement price is often a huge surprise, which may prove beneficial to some but a disaster for many others. That's because when the market opens for trading on the morning of the third Friday, there is often a gap - a significant price change from the previous night's close. This doesn't happen all the time, but it happens often enough to turn the apparently low-risk idea of holding that position overnight into a large gamble.

European index options stop trading one day earlier - at the close of business on the Thursday preceding the third Friday. Settlement Price This is the official closing price for the expiration period and establishes which options are in the money and subject to auto-exercise. Here's how it works: On the third Friday of the month, the opening price for each stock in the index is determined.

Because individual stocks open at different times, some of these opening prices are determined at a. EST and others a few minutes later. Some stocks may not begin trading until an hour or two later. The underlying index price is calculated as if all stocks were trading at their respective opening prices at the same time.

If the option is out of the money, it expires worthless and has zero cash value. When short the option, you face a different challenge:. If the option is almost worthless, holding onto it and hoping for a miracle is not a bad idea. Owners of low-priced options, worth a few nickels or less, have been known to earn hundreds, or even a few thousand dollars, when the market gapped open the following morning.
