Berkshire Hathaway has been a huge winner for its long-term shareholders. Between 1965 and 2012, the per-share book value of Berkshire has grown 586,817% (no, that's not a typo).
We can chalk a healthy chunk of those outsized returns up to the capital allocation and investing prowess of Berkshire's CEO, Warren Buffett. Over the years, Buffett has made a lot of impressive investments on behalf of Berkshire shareholders; but is it possible that one investment could be slapped with the superlative "best?"
To find out, I asked five of our Foolish analysts to weigh in.
Dan Dzombak: In two delicious words: See's Candies.
Berkshire Hathaway purchased See's Candies in 1972 for $25 million. For those unfamiliar with the company, See's is the dominant boxed chocolate company on the West Coast. Buffett has called See's a "dream business" in that the company is a market leader, has greJat customer loyalty and pricing power, and doesn't take much invested capital. That means that most, if not all, of the profits flow back to Berkshire.
Financially, See's Candies has been a great investment -- it had returned over 2,000% by 2006. However, I believe See's Candies is Buffett's best investment ever because it changed his mind-set from only buying undervalued companies to realizing that it's okay to pay up for a great business.
As Buffett said in an interview with Fortune last year:
We have made a lot more money out of See's than shows from the earnings of See's, just by the fact that it's educated me, and I'm sure it's educated Charlie, too.
Buffett has also said it taught him about the power of brands. The education provided by See's has profited Berkshire immensely over the years, thanks to this interest in great brands. Look no further than Berkshire's stake in Coca-Cola and GEICO as evidence.
John Divine: Picking Warren Buffett's best investment is like being asked to choose the best book ever written -- I think we can only choose our favorites.
That said, one investment Buffett made less than two years ago in the wake of the financial crisis shows Buffett at his finest. In September 2011, Berkshire Hathaway invested $5 billion in Bank of America . It wasn't just an investment, but a vote of confidence in B of A at a time when markets were fretting over the bank's balance sheet. Not only did the preferred shares Buffett got in return pay a cool $300 million a year in dividends, but when they're redeemed, Berkshire will get a 5% premium for them.
But here's the best part: Berkshire also has the right to buy 700 million shares of common stock at about $7.14 a pop -- anytime before 2021. At today's prices, the deal has already netted Berkshire about $3.6 billion on paper, excluding dividends and the redemption premium. The deal shows the absurd level of respect Buffett has earned from his decades of inhuman returns. No longer does his backing merely attract attention to a stock; it actually validates the underlying company.
Robert Eberhard: There are plenty of choices available when considering Buffett's best investment ever. However, I'm going to look beyond companies he's purchased, and talk about the investment he made in himself nearly 60 years ago.
Buffett was a great admirer of Benjamin Graham and David Dodd, two investment analysts who had great success, even during the Great Depression. Because of this admiration, Buffett left the comfort of Omaha in 1950 and went to New York, to study under both at Columbia Business School. He graduated with a degree in economics, and returned to Omaha to work for his father as a stockbroker.
Columbia was only part of the investment Buffett made in himself, however. Graham soon offered Buffett a position at the Graham-Newman partnership. For nearly two years, Buffett learned at the hip of one of the most successful investors ever, eventually returning to Omaha to start up his own investing partnership when Graham closed his down. It's hard to say if Buffett would be as successful today without three years of mentorship from Ben Graham, but I'm sure that it didn't hurt.
