Earlier in my career, Alan Greenspan became a sort of rock star. Via his role at the Federal Reserve, he came to wield considerable influence over the sentiment of the financial markets. In a similar but different way, Suze Orman and Dave Ramsey serve as examples of people who grew to considerable fame and influence in the field of personal financial advice; without commenting on the actual quality of their advice it is possible to observe that Orman and Ramsey share something with Oprah: their celebrity and the willingness of the public to take their advice are intertwined on some level.
I do not meant to suggest that Buffett is not an interesting topic for study and conversation; his successful record and his current status among the wealthiest people on earth is explicitly notable. I will leave the biographical blurb to the many who have covered it before me, but will restate here some facts:
Want to invest like buffett? too bad, you can't
The implication is that Buffett is primarily interested in companies he can own, not merely invest in.
Consider the deal in 2013 when Berkshire Hathaway bought Heinz. Buffett paid twenty three billion dollars for control of the company. He paid a 20% premium to the prevailing market price, and made Heinz part of Berkshire Hathaway.
Even earlier in his career, before his company had the resources to pull off $23B deals, Buffett made it his mission to amass positions in his investments sufficient to exert some measure of control.
Another way Buffett can operate that other folks simply cannot is via access he has because, well, he's Warren Buffett. Consider the example of his investment in Goldman Sachs in 2008, in the midst of the financial crisis. Calling it a sweetheart deal diminishes the very real and present danger of the financial markets at the time, but it was still a special deal. In short, because he both the interest and the capacity to make a splashy
"confidence building" purchase in Goldman Sachs in a timely manner, he got very favorable terms.
