Here is the formula from the NSE booklet I downloaded in 2009: I[t] = I[t-1] * 20th-root-of ({P[1 t]/P[1 t-1]} * {P[2 t]/P[2 t-1]} * .... * {P[20 t]/P[20 t-1]}) Where: I[t] = index at time t I[t-1] = index at time t-1 P[j t] = price of stock j (i.e., 1, 2, 3, 4, .... 20) at time t P[j t-1] = price of stock j at time t-1 You see it is just an average of prices. There is no mention of capitalisation. Unfortunately, this booklet is not available in the new-look NSE website, otherwise I'd have given you the link. Now go check you facts and let's compare. @Mukiha since you are an elder i will save you from the bashing  you need to read further http://www.bloomberg.com...quote?ticker=KNSMIDX:IND

Since you are mathematically knowledgeable, why not test the formula I have given above. You will see that it yields the correct index for a given day. Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.

Quite a debate on the NSE index. I belief it was changed from cap weighted around the time that the all share index was introduced. Life is short. Live passionately.
