No LogicThere have been frequent examples within these markets where the trading in particular stocks shows no logic. The SP will fall for no reason for a number of weeks and then suddenly rebound.
TSGI would seem to have fallen into this category. They had lots of insider buying and then released good results on 9 Aug. Concensus targets were raised to $31 and the SP responded accordingly, rising to over $24. Since that time, we have dropped approx 13% for no specific reasons that I can see. So you can pick from non specific reasons like market jitters (Trump/North Korea, etc.), profit taking or short selling. While it's certainly annoying, from where I sit, the fundamentals are just as sound as they were on 9 Aug so eventually the SP will once again reflect that.
In the meantime, enjoy what's left of the summer and/or add to your holdings. GLTA
