Name these funds with "almost unlimited capital".
Get Barrons and take your pick. The SEC was supposed to disclose the holdings of the hedge funds including short positions. AFAIK it has not happened yet. $50 billion in capital times a minimum of 10 x leverage. They have potentially $500 billion available if not more with Middle East money and possibly money from China.
Goldman, Bear, Lehman, Morgan foolishly were allowed to go from 10 to 1 to 20, 30 and 40 to 1.
The other things is is one knows another is doing it the gang jumps in. Most of it done at CBOE and CME in Chicago. Also the source of the trades and data. If you understand the data flow - you have a big edge.
