1, the last day of the settlement month allowed by futures or options contracts. The final trading day of the contract must be settled in cash, financial instruments or according to the agreement of the futures contract.

2. Last trading day of B shares: it is equivalent to the registration date of A shares, and the last trading day of B shares is the last day of interest-bearing or interest-bearing stock trading. As long as you have B shares until the closing of the last trading day, you can have the right to send shares, send shares and distribute cash dividends. The specific date of the "registration date" of B shares can be determined by the "last trading day" of B shares.

The last trading day is a date that investors need to pay special attention to, and the warrant trading day is not the same as the warrant expiration date. In the current management method of warrants, the sixth trading day before the expiration date of warrants is the last trading day of warrants. After the last trading day, the warrants stop trading, and the warrants holders can exercise their rights, but they cannot trade. Take the put warrant of China Merchants Bank which is about to expire as an example. The maturity date of China Merchants Bank CMP 1 is September 1 day, 2007, which is the last trading day of China Merchants Bank CMP 1, backdating five trading days. After August 24th, the warrants stopped trading. I would like to remind investors that the fate of China Merchants Bank CMP 1 becoming waste paper is a foregone conclusion. Investors should wait for an opportunity to sell before the last trading day, so as not to suffer losses after the last trading day. If they don't sell, don't exercise it wrongly, so as not to make mistakes again and again and lose more.

Generally speaking, there is no specific last trading day for stock trading unless the listed company issues an accurate announcement.
