He does back his mouth with his money. He also has a long standing feud with Dan Loeb of Third Point though it's more personal than business related.
This hedge fund manger is down half a billion and added more size - seems like he is married to this losing trade and trying to talk it down with his film & political actions. There is blood in the water, and it's not from HLF. I will gladly take the other side of this trade if the 3T gets taken out - could be a nice squeeze.
The film had good reviews - so I watched it and really liked it - I certainly see his point of view now and would not go long on this company.
