One thing I check when I see a strong price rise is volumes. BDR, even today, at 1 pm, has volume of 4.22 mill compared to average daily of 4.75. So today will be substantially over average volume.
If I recall correctly from my daily lookings, with the slow steady rise from $1, the volume has been much higher than the average. I would take that to mean I belive the rise is 'solid' and not fleeting. Sellers and Buyers must be feeling win-win. Sellers cashing some profit, Buyers thinking a firm uptrend in place.
