I can't understand the article much. But, I do know various stocks have gone down recently, like banks. One of the reason is foreign investors in India are taking their money back since the U.S economy is growing and the banks have raised their interest rate.

Some Indian banks have bad loans and so their stocks are falling. But there are some stocks which can grow. https://www.livemint.com/Companies/TFqFok2W2Nc4Plx3TTd1SI/TCS-crosses--8-trillion-market-cap-after-Reliance-Industrie.html
