Be skeptical

If everybody's thinking the same way, it probably means somebody's not thinking.

Smart strategy

Charlie and I decided long ago that in an investment lifetime it's too hard to make hundreds of smart decisions. That judgment became ever more compelling as Berkshire's capital mushroomed and the universe of investments that could significantly affect our results shrank dramatically. Therefore, we adopted a strategy that required our being smart - and not too smart at that - only a very few times. Indeed, we'll now settle for one good idea a year.

Margin of Safety

If you understood a business perfectly and the future of the business, you would need very little in the way of a margin of safety. So, the more vulnerable the business is, assuming you still want to invest in it, the larger margin of safety you'd need. If you're driving a truck across a bridge that says it holds 10,000 pounds and you've got a 9,800 pound vehicle, if the bridge is 6 inches above the crevice it covers, you may feel okay, but if it's over the Grand Canyon, you may feel you want a little larger margin of safety...".

Less surprises

Obviously, we can never precisely predict the timing of cash flows in and out of a business or their exact amount. We try, therefore, to keep our estimates conservative and to focus on industries where business surprises are unlikely to wreak havoc on owners.

The worst business

The worst sort of business is one that grows rapidly, requires significant capital to engender the growth, and then earns little or no money. Think airlines. Here a durable competitive advantage has proven elusive ever since the days of the Wright Brothers.

The risk is ...

When reward is at its pinnacle, risk is near at hand.

- John Bogle

Don't expect miracles

It's in the nature of stock markets to go way down from time to time. There's no system to avoid bad markets. You can't do it unless you try to time the market, which is a seriously dumb thing to do. Conservative investing with steady savings without expecting miracles is the way to go.
