Seems silly to me to arbitrarily dump tickers like this now, or anything showing some signs of life....at least wait until the end of September, folks seem to be panic selling everything now bc of the TDA list....which is kind of stupid IMO.
Now I would probably not hold after the September deadline, as they will likely get suspended, and IF the other brokers follow suit with ETrade, then buys... and sells...will no longer be allowed on those, so they will essentially be worthless securities.
Perhaps there is a slim possibility that some could come back after getting suspended, but I'm not holding my breath about that, as historically it's been extremely difficult.
