There are a number of indications that the 47 dollar mark is going to provide support: the gap up provides support, the channel line provides support and this area provided resistance to the runup before last. if support is broken at this level then be looking for support near the 50ma. around the 40-37dollar range. the volume seems worrisome. there is heavy selling at this point, which may lead to support at 47 being broken. if so, then the lower support will be a prime buying opportunity --- around 50% correction. This is not trading advice.
