What's special about the way Warren Buffet invests?

I don't think anyone can figure it out 100% as to what makes him so successful, because then Warren Buffet's funds' own profitability will reduce, due to equilibrium effects.  WB often mentions what he purchased or sold but it is always about the past and not the future, and this information is no more useful in the market. 

He's always way ahead of the curve!

Simple Classic  value style but very important in expectation analytical  , based on  intrinsic value - the underlying fair value of a stock based on its future earnings power. But there are a few things worth noting 

I believe he focuses on the stability and going concern status of a company, the leadership profile, and uses these in addition to other factors in estimating that the value of the stock will rise in the long-term.

If you want to emulate a classic value style, Warren Buffett is a great role model. Early in his career, Buffett said, "I'm 85% Benjamin Graham." Graham is the godfather of value investing and introduced the idea of intrinsic value - the underlying fair value of a stock based on its future earnings power. But there are a few things worth noting about Buffett's interpretation of value investing that may surprise you. (For more on Warren Buffett and his current holdings, check out Coattail Investor.)

He focuses on the company that he invest in (business performance, how well it generates earnings) rather than evaluating the market and supply & demand.

He also seeks ownership in these high quality companies and cares about the long term investments.
