If you are looking for the secret which has made Warren Buffett a Billionaire, than you are at the right page as he suggests that one needs to be greedy when others are fearful. He suggests that this is a fool proof mantra to become a
Crorepati from stock market or as a matter of fact to achieve
financial freedom in life. This means that one has to have a Lion's heart to buy when the blood is in the street.
However all of us may not have this Lions' heart or as a matter of luck and to get a good price instead of best price one can use the strategy to buy in piecemeal. This means that one has to identify a good stock and buy it in the pullbacks from 20, 50 and 200 day moving averages (DMA). This way you get a good price though it will be not best price as it is an average price.
