It's more to create indices of specific sub-industries that don't already have an index. For example an athletic shoes IDX would have NKE, RBK, FL, and some others.

I see. I don't think your will get a clear advice with what weighting to go ; its really up to you. You also must have an upfront rules how to handle future additions/delisting ( and this is not so easy as its sounds). Here are some scenarios :
1. Buyouts and mergers
2. Add new
3. Delete existing
4. Dividends ( for total return)

BTW , never heard of volume weighting.

That sounds like money in the bank. Is it equal weighted or is it mkt cap based? (or something else?) do you trade SMH based on it?

Equal weighting; top 10% of the components are chosen by market cap. Right, SMH and tech indices.
