This move is now pushing OVTI within range of taking out some key technical resistance levels. That first level will be its 200-day moving average of $19.43, and that second level is its gap down day high from last September near $20. A sustained high-volume move and close above those levels should set this stock up to start re-filling some of that gap back towards $26.
