Warren Buffett literally gave a 9-minute masterclass on what makes a business worth owning, inside the interview where he explains why he broke his own rule on technology.

Eight things he teaches:

1. A good business is not one that grows. It is one that earns high returns on capital for a long time. His words: "something that you can expect to earn high returns on capital over a long period of time." Growth without returns on capital is just a bigger version of the same problem.

2. Measure it against doing nothing. Buffett points out he can put huge amounts of money into government bonds and collect payments every year with no risk. So a good business has to earn a lot more than treasuries, and be expected to keep doing it. If your business does not clear the riskless rate by a wide margin, the capital has a better home.

3. The gap between similar-looking businesses is enormous. Most banks earn 13 or 14 percent on capital. Ask anyone to guess American Express and they say something similar. It earns 30 percent plus, and Buffett is clear it "does not incur more risk in doing so than the banks that earn 13 or 14 percent." Same industry, more than double the return, no extra risk taken.

4. Charlie Munger's test: the cash has to be real. Munger pounded the idea that a business was not good just because it was doing sexy things. It had to be earning real cash, be able to pay that cash out if it wanted, and better yet be able to put it back to work inside the business. A company that earns high returns but cannot redeploy the money is worth less than one that can.

5. Time is the multiplier, so duration is the thing to protect. Buffett says a long period of time "gets to be very important because it doubles later on to the very big numbers." One great year is noise. The rate is what compounds.

6. When the facts change, retire the rule. Buffett spent decades known for not buying technology, and said so himself. His explanation for buying now is that the business changed: Google and its competitors are "laying out hundreds of billions," they are big capital spenders, and that is real money. When they were asset-light he passed and the market loved them. Now that they spend heavily, shareholders like them less and he thinks they are more likely to win. He did not change his test. He noticed the business had moved into the category his test rewards.

7. Nobody is measuring the thing that matters. Buffett says he cannot recall a report on Wall Street that gets into the internal rates of return a business is actually earning, and calls the fixation on next quarter ridiculous. He rates Alphabet ahead of 90 or 95 percent of what gets merchandised through Wall Street, on the record rather than the story. If your own reporting tracks growth and headcount but not return on capital, you are measuring what is easy.

8. Every wonderful business gets attacked, so ask how long it stays wonderful. In 1958 he helped start Data Documents, after IBM was forced by an antitrust settlement to divest half the capacity of its best business. That advantage ran out after 10 or 15 years, and he knew some of the people who caused it to run out. His closing line is the whole lesson: "It's not a question of whether it was wonderful yesterday. The question is, how long is it going to be wonderful?"

The move for an operator: run the test on your own business this quarter. What return are you earning on the capital in it, how does that compare to doing nothing, and what would have to be true for that return to survive the next ten years.
