Historical comparison of Sensex, Nifty and the S&P500

Yahoo provides data from 1997 for Sensex, from 2002 for Nifty and for 60 years or so for the S&P500

A simple averaging of historical closing day values of all 3 gives the following data:

YearOfAvging Sensex/Snp Nifty/Snp Sensex/Nifty
2009 10.58 3.44 3.12
2008 11.50 3.64 3.23
2007 10.31 2.86 3.28
2006 8.22 2.35 3.15
2005 5.77 1.76 2.96
2004 4.69 1.49 2.90
2003 3.60 1.23 2.66
2002 3.42 1.12 2.91
2001 2.87
2000 3.15
1999 2.90
1998 2.73
1997 3.52
StdDev 3.18 0.93 0.19
Avg 5.64 2.24 3.03
StdDev/Avg 0.56 0.41 0.06


Some simple inferences from the above could be:

1. The ratio of Sensex/Nifty has changed little historically. Sensex is probably a little more optimistic and Nifty fluctuates about 15% less.
2. Sensex has gone from 2.7 times S&P500 to it's current almost 11 times.
3. Nifty has risen similarly, maybe about 1% less.

On a related note: If you plot the S&P data for the last 60 years out, you can see that it definitely grows disproportionately since 1995
