DIS... no news that I found.  What I do see - and this is something I've worked into my own strategies/plans - is when there's a big volume day like there was on Monday, and volume wasn't building leading up to that spike, I tend to monitor for a few days after to see if price comes back down for a better entry.  Others here may have better explanations, but those look to me like some institutional buyer went on a buying spree and didn't care if their own demand drove up the price.  So after the buying spree ends and there are no other buyers up there, price pulls back to where the buyers/sellers were previously.  Long-term, the volume can be a bullish indicator, but some pullback is logical if price spiked with volume.  

Speculating a little, too... I've noticed on many charts that the alogs get happy when the 9 crosses up over the 50.  Not guaranteed, but happens a lot.  You get a price spike followed by a logical pullback or consolidation.  Alone it's not a buy signal for me, but when other indicators align, I love getting an entry just as the 9 is about to cross up and over.  

Earlier today had a look like it might want to come down to test the 50/20 mas and perhaps the trendline?
