一般牛市有 3-5 年的 cycle，and three major up waves。

这一轮的牛市 started from 03/2009


1st major up wave 667 - 1220; " Correction to depression fear"

2nd major wave: 1042 -1350; " Correction to double dip fear"

3rd major wave: 1220-1570； “Full recovery mode"

“We may already see SPY high in our generation”

中秋望月时的感觉，“把酒问青天， 牛市何方走“。
