The Rise of SPX & 0DTE Options White Paper

Cboe

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. With the massive increase in SPX volume, particularly 0DTE, there have been concerns around market risk associated with this growth. 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. 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.
  2. 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.
