NEW YORK (Dow Jones)--Evidently the bearish analysts who were gunning for Taser International Inc. (TASR) a couple of months ago have shot themselves in the foot - or, I should say, "feet." At least it seemed to me early in May that quite a few analysts were down on Taser, maker of stun guns for law-enforcement agencies. The cited reason seemed to be lack of prospects for expansion. But the stock has nearly doubled since hitting an early-June low, and it could gain nearly $30 more if the trend is extended. And that's one of those proverbial "big ifs." On May 7, when Taser was trading near $30.50, I agreed, for purely technical reasons, that the outlook was gloomy. I said the stock was vulnerable to a selloff to $10.79 - $10.23 target support perhaps by late June. But the column also pointed out a potential "bounce point" at $24.69. Some bounce.
