In my 15 years or so of investing, give or take, I could only remember maybe about 4 stocks that have come out of the greys. I don’t even remember most of the tickers except for one. This was EXBX.
It seems they are trading in Triple Zeroes and the daily number of trades averages about 3 per day.
If this is your definition of "that have come out of the greys" then SRGE is in real trouble.
Companies just don't rebound from a suspension - giving false hope is a bad thing.
