University of Berkshire Hathaway summary

The investing approach that defined the first part of Warren Buffett’s career was a purely quantitative one – a strategy he colorfully named the cigar butt approach. The idea was to scour the market for discarded, ugly businesses that were trading for less than the cash on their books. Like finding a soggy cigar butt on the street, it might be unpleasant, but it had one last free “puff” of profit left in it. After that single puff was enjoyed, you could toss it aside and look for another. 

The original Berkshire Hathaway textile mill, a dying business in a declining industry, was precisely this kind of investment. This method was profitable, and yet it was also laborious and limited – you could never build a truly great enterprise out of a series of discarded cigar butts.

The strategy of buying wonderful businesses created a new dynamic for Berkshire Hathaway. These companies began generating enormous and consistent floods of cash that flowed back to Omaha. This welcome development posed a new challenge: How could they intelligently reinvest this ever-growing mountain of capital to acquire even more wonderful businesses? 

The answer lies in the financial engine at the very heart of Berkshire – a concept you need to understand in order to understand their success. It’s called insurance float.

A rock-solid financial foundation built on the steady profits of the insurance business model gave Buffett and Munger something most investors lacked: the peace of mind to stay disciplined. That kind of security was priceless when the market started losing its grip on reality. During the dot-com frenzy of the late ’90s, while others were throwing money at anything with a “.com” in the name, Buffett and Munger famously sat it out. They held onto cash, ignored the hype, and took plenty of heat for being “out of touch.” But they knew better than to trade long-term sense for short-term buzz.

Their inaction was a deliberate choice, rooted in the principle of staying within their circle of competence. They avoided technology stocks simply because they felt they could not confidently predict the long-term competitive position or earnings power of those businesses. Munger wryly noted that when you mix a good concept like the internet with irrational excess, the result is still just irrational excess. 

In the fall of 2008, the entire global financial system was pushed to the brink – well, almost the entire system. In a period of total panic, when credit markets were seizing and major financial institutions were collapsing, Berkshire Hathaway stepped in as the buyer of last resort. With Wall Street gripped by fear, Buffett became “the person to call.”

He acted with speed and creativity, orchestrating a series of legendary deals that stabilized key institutions while securing extraordinary terms for Berkshire. For instance, in a matter of days, he negotiated a $5 billion investment in Goldman Sachs. The deal provided Goldman with a critical capital injection and, more importantly, the Berkshire seal of approval. In return, Berkshire got preferred stock with a 10 percent dividend, plus valuable warrants to buy Goldman common stock at a bargain for years ahead. They made similar deals with General Electric and others. This was the payoff for decades of discipline – having the capital and the guts to be greedy when everyone else was scared stiff.
