Deciding to trade a stock option requires choosing an 澳洲幸运5官方开奖结果体彩网:expiration date. Because option strategies require making modifications during the life of a trade, you need to know a stock's 澳洲幸运5官方开奖结果体彩网:option cycle and in what months its options will expire.

The expiration month you choose will have 𒊎a significant impact on the potential success of an🤪y trade, so it is important to understand how expiration months are assigned to each stock.

How Options Cycles Work

To understand how options cycles work, it's necessary to revisit the history of the 澳洲幸运5官方开奖结果体彩网:Chicago Board Options Exchange (CBOE). The CBOE was founded in 1973 and became the first market for options trading. At the time, stocks with options available werಞe assigned to one of three cycles, each with four expiry months.

The CBOE randomly assigned options cycles to each stock. Stocks in the January cycle had options expiring in the first month of each quarter. Stocks in the February cycle had options expiring iওn the middl♕e month of each quarter. Stocks in the March cycle had options expiring in the final month of each quarter.

As options trading grew in popularity, the CBOE modified its rules to give every stock an option that expired in the current month (also called the 澳洲幸运5官方开奖结果体彩网:front month) and an option expiring in the following month, in addition to two months further out (known as the 澳洲幸运5官方开奖结果体彩网:back months). So the two 澳洲幸运5官方开奖结果体彩网:near-term months are available, plus two months from the January, February, or March cycles.

For example, below is the monthly options schedule ꧂for stocks assigned to the January cycle.

So if the present month is June, the month with the nearest expiration is June, followed by July, October, and January. Note how in thꦓe January cycle, the back expiration months will always correspond to the months originally assigned to the cycle: January, April, July, 𒐪or October.  

It is the same for the February cycle. The front month and following month are available, in addition to two months further out (i.e., February, May, August, or November, whichever is closest). In the March cycle, the front month and the following month are available, along with two additional months (March, June, September, or December, whichever is nearest).

At a minimum, each stock with options available for trading will have at least four expiry months available. With monthly options, the expiry date is on the third Friday of the given month.

Adding LEAPs

Some stocks, if they are heavily favored among investors, will have options that are known as 澳洲幸运5官方开奖结果体彩网:long-term equit🔯y anticipationꦇ securities (LEAPS). If a stock has LE🦩APS, then more than four expiration months will be available.

LEAPS have expiration dates that are a year away or longer, typically up to three years. The expiry date is on the third Friday of the expiry month. The ꦅcontracts are ideal for invest🧜ors looking for prolonged exposure.

All LEAPs are assigned a January expiration month, irrespective of cycle. New January LEAPs are added in September every year. For example, January 2022 LEAPs for all eligible stock and🧸 ETF options were added 🔜on September 16, 2019.

Subsequent LEAP months may also be added. For example, LEAP options for Tesla (TSLA) include the expiry months of January 2022, March 2022, June 2022, and September 2022.

The Bottom Line

Expiration cycles fo🎶r stock options may seem a bit confusing, but if you take a little time to understand t♉hem, they become second nature.

Because you may need to make adjustments during the life of a trade, it can be very important to know what expiration months will become available in the future. Understanding the 澳洲幸运5官方开奖结果体彩网:expiration cycles is just one more way to help you increase your success rate when trading optio💟ns.
