Very low volume so who knows why it's down. Ask whoever sold at 1.7 to 1.5. Maybe their reasons are varied (POG, Ebola fears?, maybe no reason other than a loss of upward momentum has traders getting out and the thin buy side has allowed for just a few sellers to push the price down by a large percentage.
Why few buyers? Maybe a lack of buyers short term or maybe the buyers are happy to stand aside to see how far the sellers are prepared to sell down to.
