I am pretty lazy and lethargic but whenever I see an opportunity, I hope I am smart enough to act. I do have some shorts in junk bonds. I messed up in shorting the bond markets a few times in the last several years. This time its working. Eventually the 30 year bull market in bonds is going to come to an end. It may have come to an end, I don`t know.
As far as other things, when I think I see something that is a good opportunity, I invest. You may remember that I bought some airlines a few years ago, I have been buying more airlines recently. Russia, I was pessimistic about it for 46 years, I am now investing in Russia.
