TASR is a sm. cap and MAMA is a micro. Both have a float of 6 mil and small inst. sponsorship. They are presently experiencing what I would call "The Day Trader's Circus". OVTI is barely a midcap with huge inst. sponsorship. All inst. are calling this a buy. The only change you will get in OVTI is downgrades. The institutions probably see no hurry to buy until closer to next 10Q. Eventually there will be commoditization in this space. If you are looking for fast money it isn't likely to happen here any time soon. Buying and selling short in it's present range can produce a nice return and the Sch. D from hell. Trade it or sit back and wait 6 months for a decent return.
