You can double your money on a flip of a coin, but the odds are 50%. You can earn 50 times your money on a nanotech, but the odds are 1/20. Why not own all of the nanotechs, and forget about which one makes you the money? That’s exactly what the ETF PowerShares Lux Nanotech (PXN) does. By owning a basket of nanotechs, you can allow more than half of them to flop, and as long as just one makes a breakthrough, odds are you’ll profit with less risk. (Keep in mind the odds from the example were arbitrary)

There are plenty of bulls right now who disagree that the market will take a hit; if you’re in that camp, go straight ahead and buy PXN. As for me, I’ll stick with my gut and wait until the “all clear”.
