How do I invest ₹10,000?

Investing Rs 10,000 depends on your risk profile, timeframe and your current liquidity requirements. Assuming you have time on your side and you are beginning, invest it in a couple of direct plan equity index funds, preferably one tracking Nifty 50 and another tracking Nifty Next 50. Keep it simple especially if you are starting out.

Once you gain more knowledge explore direct equities as a way to generate better returns.
