I try to stay away from the standalone vs consolidate PE calculation debate.
While ValuePickr members are doing a great job tracking the consolidated PE and it will be an asset in the future, I need to compare current PE with long term historical PE then I have to use the number given by NSE India which is standalone.
Check this article on why sometime we need to stick with an “incorrect” calculation: https://www.washingtonpost.com/news/wonk/wp/2013/09/10/the-dow-jones-industrial-average-is-ridiculous/?utm_term=.105ded55414a
So while they can “fix” the calculation now, they don’t do it as it will not co-relate to the historical data.
For me, the percentage earnings growth is more important than the absolute number of earnings itself.
