I've traded stocks and commodities since 1963.

Many of these remind me of 'penny stocks' that were selling moose pasture. Their trading patterns suggest this. Lots of scummy people are now involved. When you see the price of one of these double in price with a total trading volume of say $10,000 dollars, that tells you that the market is too thin and that there would be no support when it should fall. And there is no stock exchange regulator to halt the trading.
