To add, insider trading and financial misreporting is rampant in Indian stocks. Just look at the recent Hindernberg report on Adani as a starting point. The shocking aspect is that this is accepted as the norm.
US stock markets and regulations are not without fault but they are leagues better than stocks in countries like India and China.
Oh and to add on to another excellent point you brought up - Indian regulations are unstable and change on a whim. India’s government recently proposed subjecting long term debt holdings to tax, a move that is widely criticized.
