I want to diversify beyond stocks, but sectors like Indian fintech and renewable energy seem risky due to high valuations and changing regulations. How do I weigh those risks? Additionally, can mutual funds or ETFs actually protect me if a sudden policy change impacts these sectors?

It appears that major financial players in India are adapting to keep pace with the latest market trends. With NSE profits taking a hit and Groww venturing into wealth management, where should we be on the lookout for new investment opportunities?
