Automatic Halts for Nine Corporate Actions
If you trade or own a Nasdaq-listed security, Nasdaq will require an automatic regulatory halt for certain issuer-related corporate actions. The rule explicitly lists nine categories (trading symbol changes; CUSIP changes; stock dividends equal to at least 25% of the Nasdaq Official Closing Price; forward and reverse stock splits; De-SPAC transactions; spin-offs; security-type changes; mergers/mandatory exchanges; and other issuer events Nasdaq determines appropriate).
When Halts Start and Trading Resumes
Under Nasdaq's nearly-continuous 23/5 Trading plan, mandatory corporate-action halts will be implemented after the Post-Market Hours and before the Night Session begins at 9:00 p.m. Eastern Time, and trading in the halted security will resume at 8:00 a.m. ET via the Nasdaq Halt Cross (ahead of the 9:30 a.m. ET Opening Cross). Nasdaq also describes a one-hour daily pause (8:00 p.m. to 9:00 p.m. ET) under 23/5 Trading.
