Cboe Exchange Adds Monday and Wednesday Options Expirations

## Summary

Cboe Exchange is updating its Short Term Option Series Program to allow options that expire on Mondays and Wednesdays, not just Fridays. This change helps traders get more flexible and frequent trading opportunities. The new rules take effect immediately, making it easier and faster for investors to trade short-term options with potentially better timing.

## Effects PRIA read

- Two Monday & Wednesday Weeklies Allowed: benefit, medium. If you trade options, Cboe now allows certain large stocks and ETFs to list up to two Monday expirations and two Wednesday expirations beyond the current week in addition to Friday weeklies. To be eligible a security must meet quarterly tests such as: for an individual stock market capitalization g…
- Same Strike Intervals and Series Caps Apply: mixed, low. The new Monday and Wednesday expirations use the same strike-price spacing as current Monday/Wednesday expirations: $0.50 or greater for strikes below $100, $1 for strikes between $100 and $150 (with exceptions noted), and $2.50 or greater for strikes above $150.

Using sample large-cap securities, the filing notes the program could add roughly 16% more strikes for those symbols and ISE estimated a marginal increase of 66 instances of strike breaks in 2024 (22 on Mondays after hours and 44 on Wednesdays). The Exchange expects these added expirations to encou…
