I agree and would recommend everyone through your post to buy in 3 parts...for example 50...25...25....its in percentage...whatever money you want to invest make it in 3 parts like total 10000 Rs you want to Invest...the 5000 at some point and remaining 25
...25...at some other points..This way if markets goes down...you will be buying and buying...always remember buy at dip and sell at high
