If you pay attention to and care about hour by hour movements of a stock price then you are trading, not investing, in that stock.
If you are trading TIBX then you should be THRILLED at the daily bouncing around it does; it doesn't get much better than this for a trader.
My own theory is that at least one hedge fund swooped in to buy.
Now that the stock is up about two dollars over the past two days, the hedge fund can feel comfortable to DUMP !
Remember folks, this stock is like a YO-YO.. :-)
