contracts accounting for the quadruple in quadruple witching are stock index futures stock index options stock options and single stock futures while single stock futures now only trade outside the u s the quarterly expiration of index futures and index options coinciding with the monthly expiration of stock options produces a flurry of trading despite the evocative name what happens during what is now triple witching is not a supernatural phenomenon nor a mystery market makers who ve sold expiring stock and index options contracts close out the matched hedge positions boosting trading volume meanwhile the rolling of contracts ahead of expiration also increases turnover in the options and futures markets another factor is quarterly index rebalancing also known as reconstitution on the witching day that means portfolio managers tracking rebalancing indexes including those from s p dow jones in the u s and ftse in the u k may need to trade reflecting index changes types of contracts involved in quadruple witchingnow that you know what quadruple witchings are all about let s take a look at the four classes of contracts that can expire on these dates options are derivatives which means they derive their value from underlying securities such as stocks options contracts give a buyer the right but not the obligation to trade a set number of shares of the underlying security at a given strike price at any time before options expire there are two types of options monthly stock options contracts expire on the third friday of every month option buyers pay an upfront cost known as the option premium 2an index option works much like a stock options contract but derives its value from that of an equity index rather than a single stock s share price the value of the underlying index relative to the option contract s strike price is what determines an index option trade s profitability as with stock options index options don t confer an ownership interest 3unlike stock options index options are cash settled another important distinction is that index options are european style meaning they can only be exercised on expiration date while stock options may be exercised at any time before expiration 3futures contracts are legal agreements to buy or sell an asset at a determined price at a specified future date 4 futures contracts are standardized with fixed quantities and expiration dates futures trade on a futures exchange the buyer of a futures contract is obligated to buy the underlying asset at expiry while the seller is obligated to sell at expiry index futures cash settle at expiration at the specified price with the value of the index at the time determining the trade s profitability 5 like index options index futures can be used to hedge a portfolio of stocks limiting the damage from bear markets in a bear market a trade selling a futures contract earns a profit offsetting the stock portfolio s loss the goal is to minimize short term losses for long term holdings single stock futures are obligations to take delivery of shares of the underlying stock at the contract s expiration date at a specified price each contract represents 100 shares of stock holders of stock futures don t receive dividend payments 6 even when single stock futures traded in the u s they were a minor market segment relative to the trading flows in stock options and index options and futures market impact of quadruple witchingone reason the combination of monthly and quarterly derivatives expirations generates heavy trading volume is that in the money options contracts are subject to automatic exercise requiring the delivery of the underlying shares in the case of call options call options are profitable when the price of the underlying security is higher than the option s strike price put options are in the money when the stock is priced below the strike price in either case the expiration of in the money options results in increased trading volume as the underlying shares are bought or sold to close out the options trade 7despite the overall increase in trading volume quadruple witching days do not necessarily add to market volatility while quadruple witching takes place four times a year stock options contracts expire more frequently on the third friday of every month closing and rolling out futures contractsmuch of the action surrounding futures and options on quadruple witching days is focused on offsetting closing or rolling out positions a futures contract contains an agreement between the buyer and seller in which the underlying security is to be delivered to the buyer at the contract price at expiration for example one e mini s p 500 futures contract is worth 50 times the value of the s p 500 8 so the value of an e mini contract when the s p 500 is 2 100 at expiration is 105 000 this amount is delivered to the contract owner if it is left open at expiration contract owners don t have to take delivery on the expiration date instead they can close their contracts by booking an offsetting trade at the prevailing price by cash settling the gain or loss from the purchase and sale prices traders can also roll their contracts forward a process that extends the contract by offsetting the existing trade and simultaneously booking a new option or futures contract to be settled in the future the chicago mercantile exchange delisted standard sized s p 500 index and options futures contracts in september 2021 9arbitrage opportunitiesover the course of a quadruple witching day transactions involving large blocks of contracts can create price movements that may provide arbitrageurs the opportunity to profit on temporary price distortions arbitrage can rapidly escalate volume particularly when high volume round trips are repeated multiple times over the course of trading on quadruple witching days however just as activity can provide the potential for gains it can also lead to losses very quickly gives arbitrageurs the opportunity to profit on temporary price distortionsincreased trading activity and volume can lead to market gainsmarket gains tend to be fairly modestthe potential for losses can be equally as evident as the potential for gainsreal world example of quadruple witchingthere tends to be a lot of frenzy in the days leading up to a quadruple witching day but it s unclear whether the actual witching leads to increased market gains that s because it s impossible to separate any gains due to expiring options and futures from gains due to other factors such as earnings and economic events friday march 15 2019 was the first quadruple witching day of 2019 as with any other witching day there was hectic activity in the preceding week according to a reuters report trading volume on u s market exchanges on that day was 10 8 billion shares compared to the 7 5 billion average over the last 20 trading days 10frequently asked questions
