Any specific examples of company valuations according to Value Investing philosophy?
Buffet is in a different league from other value investors. He looks for stable companies with no debt and good management. Then he looks to deeply understand the industries of candidate companies, and looks for companies that are not in commodity businesses or sell commodities that can be bought for 25% of the valuation that he believes reflects the true value of the company. Deeply understanding the market is really the key.  Consider the Burlington Northern Santa Fe Railroad, which Buffet purchased last year. Railroads benefit from higher oil prices, as they can transport cargo much cheaper than trucks. They also tend to have natural monopolies in the regions they operate in. Buffet bought the railroad just as production of oil and natural gas in North Dakota started picking up. Since pipeline capacity between North Dakota and refineries in Texas/Oklahoma is very limited, the railroad is making alot of money transporting crude.
