DTC-ineligible stocks can't be traded electornically. They have to be traded on paper. This means you can buy the stock, but you may not be able to sell it. Stocks become DTC ineligible when the trading is so thin that it isn't economically viable to trade them...the MM's don't make any money keeping the stock in inventory. Shares then have to be traded on paper, and this means $200-$700 in fees for a single trade. You can get in just fine, but getting out could be very expensive, if not impossible. I don't know how this might affect existing investments in MMTE, but I know a lot of people got trapped in SD** and HE** when they hit the DTC inelgible list this month and I just want to offer a heads up. Definately worth doing some research on and asking your broker about. Some brokers may still trade it in and out just fine. Mine doesn't.
