Option cycle refers to the expiration dates that apply to the different classes of options.

Option Series Definition An option series refers to a grouping of options on an underlying security with the same strike price and expiration month.

Front Month Definition Front month, also called "near" or "spot" month, refers to the nearest expiration date for a futures or options contract. What Is a Serial Option? A serial option is a short-term option on a futures contract that trades for the months when the underlying futures contract is not listed for sale. What Is Quadruple Witching? Quadruple witching refers to a date on which stock index futures, stock index options, stock options, and single stock futures expire simultaneously.

Public holders of options contracts, however, must indicate their desire to trade no later than PM on the business day preceding the option expiration date. Most exchange-traded options contracts follow a predetermined expiration system.

Equity stock option contracts listed on the US exchange will always expire on the Saturday that follows the third Friday of the month. An exception occurs in the case of a market holiday, in which case the expiry is on the Thursday right before Friday. For holders who need to notify the exchange of their intent to exercise a trade, it is important to know that the notification limits how late you can notify vary based on where the product trades.

Most traders do not hold an options contract until its expiration date; they will move out of the position rather than exercise it or let it expire. Traders should consult their broker regarding expiry, as some brokers will have different notification limits. Weekly options contracts are shorter than regular monthly options.

They expire every week, generally at market close on Fridays. Similar to regular options, exceptions include market holidays, in which case the weekly contract option would close on Thursday instead of Friday.

American-style index options contracts, like equity options, can be exercised any time before expiration, up to and including the third Friday of its expiration month. Similar to American-style index options, some European-style index contracts expire at the end of the day. Some options expire in the morning, however, so it is important to be aware of this and know your expiry times when trading European-style index options. This is known as exercising the contract.

If you're an option seller, you have an obligation to transact stock. This is known as assignment. On the third Saturday of the month, if you have any options that are in the money , you will be assigned. This process is known as "settlement. The transaction in these options is handled between you, your broker, and the Options Clearing Corporation. You never will deal directly with the trader on the other side of the option. If you are long options that are in the money, you will automatically begin the settlement process.

If you don't want this to happen, you will have to call your broker. Each option has a price that the buyer can buy or sell the stock-- this is known as the strike price. Technically, expiration occurs on Saturday.

That's when settlement actually occurs. But since the market's don't actually trade on Saturday, we treat Friday as the effective expiration date. With the introduction of weekly options into the mix, we now have options that expire every single Friday.

The CBOE has a handy calendar that you can download and print for your desk. For monthly SPX options, they stop trading on Thursday, and the settlement value is based on an opening print Friday morning.

These contracts are "cash settled" meaning there is no true assignment but instead you look at the intrinsic value of the options and convert it into cash. Here's where it can get weird. SPX weekly options are settled on Friday at the close. So if you are trading around OpEx with the SPX you need to check if it's a weekly or monthly contract. How do options trade at expiration?

When we look at options pricing, we generally follow a traditional model. We can look at the things that affect the options pricing, known as the greeks. We know that if the option is out of the money, it will have no directional exposure 0 delta , and if the option is in the money it will behave like stock delta.

So there is this discontinuity right at the strike price-- and the gamma of the option can be represented by a "dirac function. If you have a short option that goes in the money into expiration, you must fulfill that transaction. I found on Saturday that the short options had expired in the money, and that I now had a sizeable long position on in BIDU. Make sure your books are cleared out of all in the money options if you don't want to get assigned. If you have a sold call, you will be given a short position if you don't own the stock already.

This is known as a "naked" call rather than a "covered" call. Margin to hold this short is determined by your broker, and to eliminate the short you will have to "buy to close" on that stock.

See my full guide on options pinning. Most options are American style, but you rarely have early assignment. A good rule of thumb is if your option has no extrinsic value time premium left, then you need to adjust your position. Because of that "gamma impulse" we talked about earlier, the risks and rewards are much, much higher compared to normal options tarding.

There's two groups of OpEx trades to consider: option buying strategies and option selling strategies. Option buying strategies attempt to make money if the underlying stock sees a faster move than what the options are pricing in. The profit technically comes from the delta directional exposure , but since it is a long gamma trade, your directional exposure can change quickly leading to massive profits in the very short term.

The main risk here is time decay.
