Why Trade XSP vs. SPY? A Breakdown of the Benefits

June 1, 2023

The S&P 500 Index option suite ranges from the standard size contract, SPX®, to the Mini-SPX (XSPSM) contract at 1/10th the size of SPX, to NanosSM at 1/100th the size of XSP. One of the many questions we get is why would a retail trader choose XSP versus the popular SPY ETF option? With both XSP and SPY having similar notional size (contract value), weekly expirations and PM-settlement, they are typically considered direct competitors. But XSP has a couple of advantages over SPY.

Settlement Style

SPY options settle into physical shares of the underlying SPY, which could result in market risk. In some cases, brokers will close out positions prior to the market close in order to prevent margin calls. Conversely, XSP index options are cash settled, meaning the trading account would be credited or debited the difference between the settlement price versus the strike price at close.

XSP options are European settled at expiration, eliminating the risk of early assignment. SPY options are American style, meaning that the contract can be exercised or assigned prior to expiration. In addition, American settled option contracts also have the risk of being exercised OTM after market close (“contra exercise”), increasing potential economic and tax risk for writers. 

Tax Implications

The entire S&P 500 suite of index options have the potential ability to take advantage of 1256 tax treatment, with 60% of any gains taxed long term and 40% taxed short term.* SPY options gains on the other hand are taxed as short term capital gains (ordinary income) if held less than one year.

Extended Trading Hours

XSP is now available to trade during global trading hours, while SPY is only available during regular trading hours. Let’s look at the difference and why the added availability is an advantage. 

With XSP’s additional trading hours, traders can take advantage of market moving events around the world around the clock.
