Tradewinds also filed a 13G for Gold Reserve also. I think most of these institutional investors are just looking for a place to escape when they get a chance. My guess is someone bought in big on that Monday and Tuesday Tradewinds took advantage. It wouldn't surprise me to see a 13G filed next Feb for Steelhead and Greywolf either.
Tradewinds had to file 10 days after months end because it took them to less than 5% ownership. Greywolf and Steelhead are already less than 5% so if they sold their reporting requirement is 45 days after years end.
