Never been in an ADR that's delisted so that would be unchartered territory for me. That kind of talk has been floating around China for some time - to delist some of their stocks that the Chinese feel are "undervalued" or unappreciated over here - hasn't happened yet.
Yeh, article just came out saying basically the same thing. There was zero reaction today in the market, showing that investors aren't taking this as a serious threat, just more political posturing. I would hate to get delisted, if they tanked the stock price prior to doing so, it would be painful.
