Pattern Detected

Recent product and volume-related announcements have often been followed by modest negative 1-day moves, while dividend news drew the strongest positive reaction.

Recent Company History

Over the last few months, Cboe has consistently highlighted product innovation and strong trading activity. In February 2026, it reported record index options ADV and double-digit YoY growth across several businesses, yet the stock dipped modestly afterward. New initiatives like the BITVX index and a prediction markets framework on March 9, 2026 also saw small next-day declines. In contrast, the $0.72 Q1 2026 dividend declaration on February 13, 2026 coincided with a stronger positive move, underscoring income-focused investor interest alongside growth efforts.

Key Terms

nms stocks, depository trust and clearing corporation, dtcc, global trading hours, +2 more
6 terms
nms stocks regulatory
"plans to make all listed NMS stocks available for trading on EDGX"
NMS stocks are U.S. securities traded under the National Market System, meaning they follow standardized rules for quoting, reporting and routing trades so prices and volumes are visible across exchanges. For investors this matters because those rules tend to increase liquidity, reduce hidden price discrepancies and protect against getting a worse price than what's publicly displayed — like driving on a regulated highway with clear speed and lane rules instead of unmarked back roads.
depository trust and clearing corporation regulatory
"All trades are planned to be cleared through the Depository Trust and Clearing Corporation (DTCC)."
A depository trust and clearing corporation is a central organization that holds securities electronically and makes sure stock and bond trades are matched, finalized and recorded — like a combination of a secure vault and an air-traffic controller for financial trades. It matters to investors because it reduces the chance of mistakes or fraud, speeds up transfers of ownership and money, and helps keep markets liquid and reliable; failures or delays at this hub can disrupt trading and affect asset values.
dtcc regulatory
"cleared through the Depository Trust and Clearing Corporation (DTCC)."
The DTCC (Depository Trust & Clearing Corporation) is the central organization that records, moves and confirms ownership of securities and money after trades, functioning like a giant, highly secure post office and accounting book for the financial markets. It matters to investors because it ensures that buys and sells are completed correctly and quickly, reduces the risk of lost or duplicate transactions, and underpins trust and stability in the market.
View in glossary
global trading hours technical
"Trading in Cboe's proprietary index options during Global Trading Hours (8:15 p.m. to 9:25 a.m. ET)"
Global trading hours are the times when stock, bond or commodity markets around the world are open for buying and selling, including the overlaps and after-hours periods created by different time zones. For investors this matters because extended or staggered hours affect when prices move, how easy it is to buy or sell, and how quickly news from one region can influence markets elsewhere—like a 24-hour marketplace where activity shifts as different time zones wake up.
average daily volume financial
"has seen a 590% average daily volume (ADV) growth from February 2022 to February 2026."
Average daily volume is the typical number of shares or contracts of a security traded each day, calculated by averaging daily trading amounts over a recent period. It matters to investors because it indicates how easy it is to buy or sell without moving the price—like traffic on a road: high volume is a busy freeway that lets many cars pass smoothly, while low volume can make large orders cause big price changes and higher costs.
View in glossary
adv financial
"has seen a 590% average daily volume (ADV) growth from February 2022 to February 2026."
ADV stands for Average Daily Volume, which shows how many shares or units of a stock or asset are traded on average each day. It helps investors understand how popular or liquid an investment is—like knowing how many tickets are sold daily for a concert, indicating how much people are buying and selling.

CHICAGO, March 16, 2026 /PRNewswire/ -- Cboe Global Markets, Inc. (Cboe: CBOE), a leading global markets operator and pioneer in equity derivatives, announced it submitted a proposal to the Securities and Exchange Commission (SEC) to launch near 24x5 U.S. equities trading on its Cboe EDGX Equities Exchange (EDGX). Cboe is preparing to launch in December 2026, pending regulatory approval of its filing, and contingent upon the readiness of required industry infrastructure providers.  

In its filing, Cboe outlines its plans to make all listed NMS stocks available for trading on EDGX from Sunday 9 p.m. ET to Friday 8 p.m. ET, with a one-hour operational pause 8 to 9 p.m. ET Monday through Thursday. This will allow for near 24x5 trading, excluding U.S. market holidays. All trades are planned to be cleared through the Depository Trust and Clearing Corporation (DTCC).

"Cboe's filing with the SEC is the latest step in ensuring we are ready to offer overnight trading once the industry launches in December. Since announcing our plans for near 24x5 trading amid growing global interest for U.S. markets, we have been engaging with clients and market participants across the globe, underscoring the importance of collaboration throughout this process," said Oliver Sung, Head of North American Equities at Cboe. "Cboe has a strong track record of operating liquid, around-the-clock derivatives and FX markets, and will leverage that expertise to ensure robust market and investor protections are in place."

Demand for U.S. equities outside of traditional trading hours has grown significantly over recent years, evidenced by the growth in Cboe's U.S. Equities Early Trading Hours volumes. Cboe currently offers trading from 4 a.m. ET to 7 a.m. ET on two of its four exchanges, including EDGX, and has seen a 590% average daily volume (ADV) growth from February 2022 to February 2026.

Cboe has successfully operated around-the-clock trading through its proprietary index futures and options and its Global FX markets for several years. Trading in Cboe's proprietary index options during Global Trading Hours (8:15 p.m. to 9:25 a.m. ET) is at record levels in 2026, as investors look to hedge positions or reposition as needed, particularly during pre-market news. Cboe FX, which offers a true 24x5 market, operates a follow‑the‑sun operations model with continuous operational coverage, incident response, and client support across all global time zones.

Outside of regulatory approval and infrastructure readiness, critical components to launching overnight trading include increasing market access and the availability of high-quality, real-time data. Cboe continues to expand distribution of its Cboe One U.S. Equities Feed, which offers consolidated, real-time market data from Cboe's four U.S. equities exchanges. In 2025, Cboe's four exchanges accounted for 20.2% of U.S. equities on-exchange trading.

"Cboe understands that accurate and reliable market data is the foundation for making informed investment decisions," said Brian McElligott, Head of Cboe Data Vantage. "We continue to focus on expanding the availability of our U.S. equities data offerings, reflecting the strong desire for access to U.S. markets from Europe and APAC investors. Whether it's real-time, top-of-book, or historical data, Cboe Data Vantage is helping investors navigate today's markets and prepare for U.S. equities overnight trading."
