Weekly options provide a deep pool of liquidity for you to express views on market-moving events and economic announcements – from national elections to monthly employment and inflation reports – nearly around the clock.
CME Group continues to see strong liquidity during extended trading hours, especially in short-term options, with a 90% participation rate in Extended Trading Hour (ETH) S&P volume in Q1 and Q2 2019.
Starting July 29, the listing cycle for Monday and Wednesday options will be extended to provide you with more opportunity to fine-tune your trading strategies. Traders can execute their options overlay strategies with greater flexibility across four different weeks.
Listing cycles will be extended from 2 to 4 expirations in both Standard and E-mini Monday and Wednesday S&P 500 options on futures.
1 - On their expiration day, weekly and EOM options will be automatically exercised if the options are determined to be "in-the-money" using a volume-weighted average fixing price calculated by the exchange at 3:00 p.m. Central Time (CT). This special fixing price is calculated and disseminated by CME daily under the symbol "ESF."
