Hi All,

Can anyone give me a formula (not AFL) to use to construct indices
from the underlying stocks?

A simple way is to add the close of all stocks in the index
under construction and divide by the number of stocks.  Simple, yes;
but is it a sound way to present the data?

One could also weight by some factor, but which one?

I'm interested in seeing your ideas, particularily if they represent
the way a finacial service firm (ie: Media General, Standard and Poors)
would do this.

Regards,

Tony
