We have learned to turn out lots of goods and services, but we haven't learned as well how to have everybody share in the bounty. The obligation of a society as prosperous as ours is to figure out how nobody gets left too far behind.
I'm always interested in understanding the math of things and understanding as much as I can about all aspects of business. And what I learn today may be useful to me two years from now. That's really the wonderful thing about investments is your knowledge is cumulative.
The American economy is going to do fine. But it won't do fine every year and every week and every month. I mean, if you don't believe that, forget about buying stocks anyway... It's a positive-sum game, long term. And the only way an investor can get killed is by high fees or by trying to outsmart the market.
An argument is made that there are just too many question marks about the near future; wouldn't it be better to wait until things clear up a bit? You know the prose: "Maintain buying reserves until current uncertainties are resolved," etc. Before reaching for that crutch, face up to two unpleasant facts: The future is never clear and you pay a very high price for a cheery consensus. Uncertainty actually is the friend of the buyer of long-term values.
I look for businesses in which I think I can predict what they're going to look like in ten to fifteen years time. Take Wrigley's chewing gum. I don't think the internet is going to change how people chew gum.
I don't know that I could draw one that's perfect. But I'd rather by approximately right than precisely wrong, and it would be precisely wrong to turn it down.
I do not like debt and do not like to invest in companies that have too much debt, particularly long-term debt. With long-term debt, increases in interest rates can drastically affect company profits and make future cash flows less predictable.
We say we are trying to buy into businesses with excellent economics, run by honest and able people at a decent price. We buy very few securities, so we look at it as "focused" investing.
