Stocks - You gotta do your own research and comes with a bit of risk.  
 If you have lump sum you can buy land in an underdevloped area that has potential . Even commerical property is a good bet.

Stocks is too much of a hassle tbh. You need to always be on top of it.  
 I have been thinking of land earlier, but it is too long term

Commercial property does sound interesting.  
 Can you tell me more about it?

Very small portion of Angel investing and invoice discounting

I have been wondering if there are other instruments that can also yield good returns in long term. 

Can you guys share if you are aware of any

Apart from investing in MFs and FDs, what other instruments are you using?
