The Zero Hedge audience have always been tough task masters and will hold people's feet to the fire. While markets have been a little tempestuous to say the least recently, TrimTabs' Charles Biderman comes out swinging with a spirited and honest defense of his calls - and quite frankly we still tend to agree with his bigger picture view of where this ends. From his Facebook miss to short-term fluctuations in the equity market (that now seem precipitously away from credit market reality), Biderman responds to comments here and elsewhere on both position sizing and perhaps most importantly risk management - adding (and this is where we believe he is dead right though timing the call is practically impossible) that "when the collapse happens it will happen overnight - that is why [he wants] to be short but safe at the same time."
