[Sola Fide]

Pull up a chart and compare average volume and highest daily volume for the last year or so....
You'll find today's volume was in the upper level, this isn't a stock that typically trades even a million shares and did 4x that today.
One could also compare the average daily # of trades as compared to today's.
I would concur that a 40% drop isn't as large as often happens with sell offs, but certainly its enough to warrant concern.
