NYSE Sharpens Halt Rules for Reverse Stock Split Shenanigans
Published Date: 9/3/2026
Notice
Summary
The New York Stock Exchange (NYSE) is updating its rules about when to pause trading on stocks that go through a reverse stock split—a fancy way of saying the stock price changes because the company shrinks the number of shares. This change helps the NYSE act faster and clearer when stopping trades to keep things fair and smooth. It’s effective right away and mainly affects companies listed on the NYSE and their investors.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Reverse-split trading halt timing clarified
If you own NYSE-listed stock that is doing a reverse stock split, the Exchange can halt that security before the end of post-market trading on other markets on the day immediately before the split’s market effective date. Trading will resume with a Trading Halt Auction after 9:30 a.m. Eastern Time on the next trading day.
Rule correction became effective immediately
The NYSE rule correction was filed on August 18, 2026 and became operative immediately because the SEC waived the usual 30-day delay. That means the clarified Reverse Stock Split Halt wording applied as of the filing date.

2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
