What can investors do when a stock is going to be delisted?
Investors in the Chinese telecom carriers can sell their ADRs on NYSE before they are delisted or convert them to the Hong Kong-listed ordinary shares. But the U.S. ban also prohibits American investors from buying securities that trade on any exchange anywhere, or even just over-the-counter, so switching into Hong Kong shares might only buy a few months’ respite.
What happens if investors don’t trade in their ADRs?
There is no requirement to sell until November, so investors could hold on until then.
