Have to go back, it was about 4 years ago when at MSTX was at $1.20 when I first bought. Then a failed test it dropped big time. Double 3 times, about once a year, and adding about a thousand a week in the last 2 months. Not as much as others here but I am not a professional investor as some here are. Have about 100,000 shares last check.
Not real happy about MSTX, but 2 other stocks in similar situations I did the same strategy. Double the investment, ride the wave and get out when in positive territory. Could kick myself with KERR. Doubled investment, got out after doubling money at $3.00 to buy more MSTX only to see MSTX go south while KERR goes to $15.00. That's why I share "only invest what you can lose." Good luck ...
