The Rise of SPX & 0DTE Options White Paper


U.S. options markets have seen significant growth in trading over the last few years, with volume in 2023 on pace to be a record for the fourth year in a row.

We look at the trends in both overall and short-dated SPX options trading, including overall volume growth, SPX volume and open interest, the history of SPX 0DTE, typical uses of 0DTE options, quote quality in SPX, costs to trade SPX, the benefits of shorter dated options and addressing some concerns related to the recent 0DTE boom.

  1. Under section 1256 of the Tax Code, profit and loss on transactions in certain exchange-traded options, including SPX, Mini-SPX (XSP) and Nano options, are entitled to be taxed at a rate equal to 60% long-term and 40% short-term capital gain or loss, provided that the investor involved and the strategy employed satisfy the criteria of the Tax Code. Investors should consult with their tax advisors to determine how the profit and loss on any particular option strategy will be taxed. Tax laws and regulations change from time to time and may be subject to varying interpretations.
  2. Nanos trade on Cboe® as a $1 multiplier option (versus a $100 multiplier for standard options) on the Mini- S&P 500 Index, which is 1/10th the value of the S&P 500 Index. While capital risk for a contract holder is limited to the price of the premium and is thus reduced relative to the same number of standard contracts, the capital risk associated with writing Nanos by Cboe® contracts remains open-ended.
  3. Global Trading Hours (GTH) The trading hours for options on the SPX, SPXW (SPX Weeklys and SPX End-of-Month), and SPXPM begin at 8:15 p.m. Eastern time and end at 9:15 a.m Eastern time. Please visit the Trading Hours page for more details.
