pete, if one looks at the 9 SP500 sectors only financial XLF and the consumer discretionary XLY sectors took out the august lows. these are the sectors most affected by the recent financial problems. we either saw a 10 wk low around oct 22 or 24 and the very recent decline has been a cycle straddle for broad indexes due to the financial news, or we had a slightly longer 10 wk cycle (12+ wks)which has or is bottoming now. i'm updating a commonality model to see if that can be resolved. as far as the 4.5 yr cycle bottom, if Hurst's cycle model and the accompanying cycle principles have any validity, the august 07 low should be the resolution for that bottom.
