It looks to me like SIRI is overbought short term. I say it fills the gap back down and could eventually bounce of the 200dma at around .75 before it moves up. One thing that may have started the downward momentum is that traders could be selling and moving into YRCW with expectations of even a bigger run that SIRI.
SIRI to .75 then to $2.00.
YRCW straight to $2.00 from .46.
This stock loves to test the 200dma. Currently that area is around $2.00.
SIRI has a quality product and near monopoly. YRCW has a mediocre product and many competitors. I've invested in SIRI recently, took profit and got out. I would never invest in YRCW because it has a crappy service product, and LTL industry has way too much excess capacity right now. YRCW would have already gone bankrupt if it wasn't for fed gov't telling GS to find a way to make the bond deal go through.
