In Seth Klarman's most recent annual letter, he lists some of the true and false lessons of the financial crisis. Here are some selected ones that I like (taken from the true section) in no particular order:
9. You must buy on the way down. There is far more volume on the way down than on the way back up, and far less competition among buyers. It is almost always better to be too early than too late, but you must be prepared for price markdowns on what you buy.
10. Financial innovation can be highly dangerous, though almost no one will tell you this. New financial products are typically created for sunny days and are almost never stress-tested for stormy weather. Securitization is an area that almost perfectly fits this description; markets for securitized assets such as subprime mortgages completely collapsed in 2008 and have not fully recovered. Ironically, the government is eager to restore the securitization markets back to their pre-collapse stature.
12. Be sure that you are well compensated for illiquidity – especially illiquidity without control – because it can create particularly high opportunity costs.
13. At equal returns, public investments are generally superior to private investments not only because they are more liquid but also because amidst distress, public markets are more likely than private ones to offer attractive opportunities to average down.
14. 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.
There are a total of 30 lessons (20 true, 10 false) on the list.
This site does not provide investing recommendations as that comes down to individual circumstances. Instead, it is for generalized informational, educational, and entertainment purposes. Visitors should always do their own research and consult, as needed, with a financial adviser that's familiar with the individual circumstances before making any investment decisions. Bottom line: The opinions found here should never be considered specific individualized investment advice and never a recommendation to buy or sell anything.
