Many years ago, I came across something called the 'Vice Fund', a fund that invested in tobacco, alcohol, and guns. They had some numbers that showed that they tended to do really well when the overall market went down, and have slightly worse returns than average when the market was doing well.
If I could find them again, I'd probably invest...

If they include book-keeping and junk or fast-food, I'm in too!
