hi narayan,
you may visit the link below:
http://in.finance.yahoo.com/intlindices?e=americas
but the important indices from this link are taken and with a weightage given to each, a single number world index was attempted to be arrived at in the tetracool's coolintra spreadsheet.
this single number %Change value is expected to represent the world's mood at any point of time, particularly before the opening of the indian markets, which is of great relevance to us.
suggestions for improvising this methodology are welcome & cool will be too happy to incorporate the accepted changes.
