Cboe offers End-of-Month options series (EOM) for its SPX options. SPX EOM options feature expiration dates that fall on the last business day of the month, as opposed to the standard third Friday of the month expirations. SPX EOM options allow asset managers to more precisely match SPX option expirations to end-of-month fund cycles and fund performance periods.
