Indian equity market follows the US Presidential election year cycle. This coincides with the '8-year itch' model of CNBC-TV18, which states that after every 8-years equity markets peak out. This is evident since 1984 and is based on 24 years of empirical data. Earlier, the markets peaked out in 1984, 1992, and 2000. Based on this theory, the next peak out is supposed to happen in 2008. 

It depicts that India has not decoupled with the US. The market peaks out during election year only to see sharp sell-off thereafter. The average recovery period is around 10 months.
