Lol they don't know difference between GDP and market valuation ? GDP is total value of products and services produced in a country in a span of year . It means india produces 4tr worth of of product of services a year and its growing at 7 percent .
Putting market cap on a country is job of a stupid person . Countries are not sold in share market

... Market cap is the total valuation of all the shares in share market .
I had to explain this stupid thing only because I have seen this shit many times ..
