Hi Mohan
Sure my friend.
Btw
1)It is easier to use the beta formula directly.
2)That depends on your need. If you need latest data all you have to do is take the data from
www.nseindia.com(For stock data try Home/equity/historical data link and for Index data Home/Indices/statistics/historical data Link) and cut and paste the data to the attached sheet. When you cut and paste it just make sure that the value of N(no. of observations) is changed in the formula. (Whereever B257 appears in formula change it to the actual no. of observations).
3)The sheet is not part of any report. Just my own.
Thanks
