check the COT... large specs are net long right now, how do they get 'very short'?
anyway - it's not about retail schmucks moving the market.... it's about where they have been pushed to, by the brain washing from the smart money, be that commercial or large spec.. hence the perfect contrarian indicator.
COT, commercial, large specs are difficult to read. Commercial may have the first hand info, but some are forced to hedge because they are commercial and have to keep the biz running... large spec is a mixed bag, you have some really smart people there.
but small specs - you can categorically call them the dumb money.
