DERIVSOURCE: Smaller Contracts Expand Across U.S. Listed Derivatives
CME Group launched E-nano equity index futures on August 24, tracking the S&P 500, Nasdaq-100, Russell 2000, and Dow Jones. These contracts are one-tenth the size of Micro E-mini contracts, aiming to increase market accessibility. CME reported strong growth in its Micro E-mini contracts, with July volumes up significantly. Other exchanges, like Cboe, also offer smaller contract sizes. The E-nano futures can be offset against Micro E-mini and E-mini futures.
