As Berkshire Hathaway's class-A share (BRK.A) is approach a six-figure price, MarketWatch briefly reviews Warran Buffett's success. We might never see Berkshire Hathaway to break seven figures ... it is more a value play than a growth story, and the law of large numbers has already hit the stock (thinking about Buffett's $40 billion cashpile).

(P.S. I hold six shares of BRK.B in my portfolio. Nice gain of 14% in about a year's time. It is a keeper!)

The charming Buffett not only keeps investors rich, happy and satisfied, he keeps them amused with the wit he displays in his annual letter to shareholders and holds their trust via such acts as a paltry $100,000 salary. He also plans to devote much of his $42 billion in net worth to charity.

Don't expect Berkshire shares to hit the $1 million mark in the next decade, said Whitney Tilson, manager of the Tilson Focus Fund. While Tilson is a fan of Berkshire and has owned shares in the company since he started investing, growth rates show that it may take until the mid-2020s for Berkshire to reach that even loftier height.

The time it takes for Berkshire to gain a digit in stock price is getting longer, as it took six years to go from $100 to $1,000 and will take 14 years to go from $10,000 to $100,000.
