  1. just a quick question..where do you find the P/BV ratio of a particular script…tried googling but no luck. Keep up the good work..I like reading your site..

  2. Hey!

    Can you also provide a CAGR formula for monthly payments which culminate into a bulk yield at the end of x years.

    E.g.: If I pay 3k per month for 15 years and the maturity value is 15 lacs, what is the effective CAGR of this investment?
