"If you aren't willing to own a stock for 10 years, don't even think about owning it for ten minutes," said Buffett in one of his interviews. 

Warren Buffett believes that an investor should buy and hold on to his/her investments to earn the most.

This is one of the most famous lines, which he has shared at number of  occasions. Buffett says, "When others are greedy, I remain fearful and  when others remain fearful, I turn greedy."

Investor should prefer buying undervalued stocks. The undervalued shares are those stocks which possess huge capacity to return high on investments but remain outside the portfolios of people.

The investor should ideally perform a proper research before picking these companies and invest in fixed patterns.
