Correlation between Indian and US Stock Markets

I invest (modestly) in both US and Indian stock markets. For the last few days I observed that on the days when US market was down, the Indian market was not necessarily down.

When I posted my observation on Facebook, people asked me for more concrete evidence for a lack of this correlation.
