Warren Buffett's Berkshire Hathaway purchased 1.13 million more shares of DaVita HealthCare Partners this week, raising its stake in the kidney dialysis company to 17.7 percent.
The purchases bring Berkshire's total stake in the company to 37.62 million shares. At Wednesday's close of $67.50, the stock had a market value of $2.54 billion.
Warren Buffett says if you want to learn how to make money from the stock market you should look at how he made some money with two small real estate investments.
In an excerpt published by Fortune, from his upcoming annual letter to Berkshire Hathaway shareholders, Buffett writes about his purchase of a Nebraska farm and his investment in a retail property near New York University in Manhattan.
In both cases, he bought when prices were unusually low after bubbles had burst.
In both cases he had no particular expertise.

And most importantly, in both cases he invested because he thought the assets would be increasingly profitable, not because he expected to sell at a higher price.
After consulting with Chairman and CEO Warren Buffett, Berkshire Hathaway subsidiary Business Wire has decided to cut off the high-frequency trading firms that were paying big money to get news releases and economic reports through direct feeds from the company.
Business Wire has been under pressure from New York regulators since The Wall Street Journal reported earlier this month that the direct access gave the HFT firms "the ability to trade fractions of a second ahead of less fleet-footed investors."
The moves are all relatively small, however, especially by Berkshire standards.
The Dish shares were worth about $31 million at the current price, and the Glaxo stake totaled only $19.3 million, indicating that they were handled by one of Berkshire's portfolio managers rather than by Buffett himself.
The filing didn't identify what part of Graham Holdings Berkshire might be interested in buying.
Buffett put his money behind his long-held argument that "experts" don't do better than the stock market as a whole. It's the basis of his argument that the fees "helpers" charge investors usually aren't justified.
In a Fortune piece, long-time Buffett friend Carol Loomis writes that after six years the fund Buffett selected for the wager, the Vanguard 500 Index Fund Admiral Shares, was up 43.8 percent at the end of 2013.

Last month, Warren Buffett and Dan Gilbert, founder of Quicken Loans, said they would pay $1 billion to anyone who could pick the perfect NCAA March Madness bracket, but it appears that Yahoo may have had the idea first.
A Dallas-based sweepstakes company is claiming that it is owed $4.4 million by Yahoo for backing out of a similar contest that would have paid $1 billion for a perfect bracket as well, Fortune reported on Tuesday.
According to a lawsuit filed last week, Yahoo signed a deal with SCA Promotions late last year, but canceled the contest shortly after Gilbert and Buffett announced theirs.
Dow Chemical Chairman and CEO Andrew Liveris told CNBC on Wednesday that Warren Buffett supports his vision for the company.
The Buffett praise comes as activist investor Daniel Loeb is putting pressure on Dow to spin off its lucrative but slow-growing petrochemical unit and focus on specialty materials.
Liveris revealed in a "Squawk Box" interview that he met with Buffett this week, and the Berkshire Hathaway boss said: "'We're an owner and we like being an owner. And frankly, we think you've been running the company for the investors who will stay versus the investors who will leave.'"
A Buffett representative confirmed this exchange.
In 2008, Berkshire Hathaway helped to finance Dow's deal to buy specialty chemical maker Rohm and Haas for over $15 billion in cash. Berkshire contributed an equity investment of $3 billion worth of convertible preferred securities.
Liveris said he and Buffett are working together "on the best way to do those preferreds, [which] is to let them earn themselves out. He's in the money. He's now an equity investor. ... When it gets to $53.70, they will disappear."
Federal regulators have begun to look at Warren Buffett's Berkshire Hathaway to see if its failure would be damaging enough to threaten the country's financial stability, according to a report by Bloomberg.
It quotes "two people with knowledge" of the matter as saying the staff of the U.S. Financial Stability Oversight Council, led by Treasury Secretary Jack Lew, wants to determine if Berkshire is so important to the health of the financial system that it needs special supervision by the Federal Reserve.
Warren Buffett and Dan Gilbert, founder of Quicken Loans, are teaming-up to offer $1 billion for the perfect NCAA March Madness bracket.
Buffett's Berkshire Hathaway will be insuring the grand prize. It would be shared by any qualified contest participant who predicts the winners of every game in the men's college basketball tournament, which is set to begin on March 18. The billion dollars would be paid in 40 annual installments of $25 million each.
The winner (or winners) may also choose to get a lump sum payment of $500 million (or share in that amount).
In addition to the potential grand prize, Quicken said it'll award $100,000 for each of the 20 most accurate "imperfect" brackets in the contest to use toward buying, refinancing or remodeling a home.
Quicken will also be directly donating $1 million to nonprofit education organizations in Detroit—the city in which its headquartered—and in Cleveland.
Gilbert, a billionaire himself, also owns the NBA's Cleveland Cavaliers.
