Increasing your core position is a good idea. With most penny stocks you can buy low and sell most of your position higher for a 10 or 15 percent gain. With TDGI it is going to get more difficult to do these swing trades because there will not be many shares to buy back after you sell your position. You may sell the 200k position you have for a decent gain, but then when you try and buy it back they will only give you small amounts at a time, which in effect will cost you more to buy your position back. There is just to much happening with TDGI to take the gamble that you will be able to make a profit on a swing trade, you may win the battle but loose the war. I too have been holding a much larger core position then i normally do, but I truly believe it is the best way to play this stock at this time.
