Here goes nothing-Classic Mo trades vs Reversal trades.
1)Baskets
2)Fresh Money
1)Baskets
Alot of stocks are put into baskets and traded as basket instead of on their own fundamentals. Ystr, AIG, Lehman, Wamu traded up huge vs market direction. Today, that triplet is trading in parallel and down. Thats what I see. Within this group you could add FRE and FNM. The list goes on....
IMO: The Q's ran up hard. The metrics you cited worked. Looked higher today from ystr metrics. But today, trades that were not completed ystr were completed at the opening. AIG knocked down the basket value at open.
Then: Fresh money came. Saw big move ystr, bet against it. Ystr trader vs holders sold off winners. We have down day. What is alway difficult to size up is "FRESH MONEY TRADERS." Dont try. They are silent and move as a group.
