I don't know that there is a consensus what caused the move. My feeling is that it was good fundementals and good performance....................which found a wider audience at the Vegas conference which prompted buying.
But, it is moving on fundementals mostly and then on future promise. I can't wait for the new head mounted displays start coming out. I can use some of my profits to buy one from a manufactuer using HIMX parts and call it investment research. I wonder if I can slide that by the IRS?
