Often there are buyouts or corporate actions or other reasons that cause a stock to be removed from an exchange (delisted). Given a specific company and specific situation, it's often possible to find a report submitted to the exchange or published by the company that indicates that a stock will cease trading on that exchange sometime in the future. Reports I've seen often do not include a specific date for delisting.
Given an exchange (NYSE, NASDAQ, AMEX, etc), is there a schedule or calendar that specifies when specific stocks, currently still on the exchange but with a future plan of being delisted, will no longer be traded or become de-listed?
