S&P 500 and E-mini S&P 500 Wednesday Weekly options on futures will be available for trading beginning September 26. The addition of Wednesday Weekly options provides you with the opportunity to fine-tune your trading strategies, particularly ahead of market-moving events and reports. New Wednesday options will trade like existing Weekly Index options, but they will expire on Wednesdays instead of Fridays.
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."
Weekly options provide a deep pool of liquidity for market participants to express views on market-moving events and economic reports, such as monthly employment and inflation reports, earnings announcements and dividend changes.
On employment report days, which generally coincide with Week 1 option expiration, trading in the expiring E-mini S&P 500 weekly and the next weekly option often exceeds ADV by 100%.
