Mr. Buffett shared some of his other investment mantras: Picking the right stock

Mr. Buffett shared some of his other investment mantras:
Picking the right stock
Mr. Buffett reiterated that he relies on principles taught by his guru, investor Benjamin Graham, who looked for stocks which were cheap compared to their worth. (Of course, the key is to figure out what the stock is worth, which is a subjective decision.)
Mr. Buffett said he doesn't look at sectors to identify stocks.
Instead, he looks for companies whose business he understands, and where he sees income and growth potential for the next five, 10 or 20 years.
He gave the example of Coca-Cola , one of his holdings. What are the chances that Coca-Cola will be selling more products over the next several years? "It's almost a certainty," said Mr. Buffett.
In comparison, he has stayed away from some technology and social media companies like Twitter or Facebook, which operate in a fast-changing world where the future is not clear to him. Some of these companies will be very big winners but "most of them will turn out to be overpriced," said Mr. Buffett.
He said he doesn't have to be a part of all successful companies – he looks for only a few good investing ideas.
