The cost of performing well in bad times can be relative underperformance in good times.

Investors need to pick their poison: Either make more money when times are good and have a really ugly year every so often, or protect on the downside and don't be at the party so long when things are good.

Ratings agencies are highly conflicted, unimaginative dupes. They are blissfully unaware of adverse selection and moral hazard. Investors should never trust them.

The government can indefinitely control both short-term and long-term interest rates.

Successful investors like stocks better when they’re going down. When you go to a department store or a supermarket, you like to buy merchandise on sale, but it doesn’t work that way in the stock market. In the stock market, people panic when stocks are going down, so they like them less when they should like them more. When prices go down, you shouldn’t panic, but it’s hard to control your emotions when you’re overextended, when you see your net worth drop in half and you worry that you won’t have enough money to pay for your kids’ college.

Beware leverage in all its forms. Borrowers - individual, corporate, or government - should always match fund their liabilities against the duration of their assets. Borrowers must always remember that capital markets can be extremely fickle, and that it is never safe to assume a maturing loan can be rolled over. Even if you are unleveraged, the leverage employed by others can drive dramatic price and valuation swings; sudden unavailability of leverage in the economy may trigger an economic downturn.
