Look down, not up, when making your initial investment decision. If you don’t lose money, most of the remaining alternatives are good ones.

Value investing doesn't always work. The market doesn't always agree with you. Over time, value is roughly the way the market prices stocks, but over the short term, which sometimes can be as long as two or three years, there are periods when it doesn't work. And that is a very good thing. The fact that our value approach doesn't work over periods of time is precisely the reason why it continues to work over the long term.

I still believe that for good business analysts a concentrated portfolio is a good strategy combined with a long term horizon. Once again, the secret to success in following the formula strategy is patience, a quality in short supply for both professionals and individual investors alike. I think investors should have a large portion of their assets in equities over time.

Figure out what something is worth and pay a lot less.

Choosing individual stocks without any idea of what you're looking for is like running through a dynamite factory with a burning match. You may live, but you're still an idiot.

I think the exercise of trying to figure out how to simplify concepts has been incredibly helpful to me over the last 13 years of teaching and I hope my students have benefited from it.

Over the long term, despite significant drops from time to time, stocks (especially an intelligently selected stock portfolio) will be one of your best investment options. The trick is to GET to the long term. Think in terms of 5 years, 10 years and longer. Do your planning and asset allocation ahead of time. Choose a portion of your assets to invest in the stock market - and stick with it! Yes, the bad times will come, but over the truly long term, the good times will win out - and I hope the lessons from 2008 will help get you there to enjoy them.
