Invest like Warren Buffett ...

Warren Buffett is the world's third richest man with an estimated fortune of over $52bn.

But unlike the other billionaires that feature in Forbes' list of the 10 richest people in the world, Buffett doesn't have a retail empire, an oil well or a brain for computing to show for it – simply a lot of share certificates.

The 76-year-old made his money through identifying companies that he believed were worth more than their market value, investing in them and holding that investment for the long-term. And it's certainly paid off.

Class A shares in his company Berkshire Hathaway were $15 when he first took over in 1965 – today they are valued at $109,800 per share.

It sounds remarkably simple, but given the ups and downs of the stock market, it takes a high level of discipline, nerve and conviction in your decisions. Although Buffett has never written a book detailing his investment style, much can be gleaned from the annual letter he sends to Berkshire shareholders.

He doesn't view the purchase of shares in a company as buying a stake in that business, but believes that the investor should feel that they are actually buying that business outright. Because of that he looks for quality management, a durable competitive edge and low capital expenditure.

Companies tend to have a strong brand name – Coca Cola, McDonalds and Gillette feature in his holdings – and a good history of solid earnings growth. We run through how Buffett invests his money.

'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'

The basic premise of Buffett's investing style is buying something for less than it's actually worth. This sounds simple enough, but unearthing these stocks and prove difficult and it's easy to mistake a company that is unloved by the market because nobody has spotted its opportunity with one that is simply a dog. For that reason, Buffett applies some of the measures that are listed below.
