People look at a classic Ferrari at the 'Salon Prive' luxury and supercar event on June 22, 2011 in London, England. - 

This final note today, if the equity markets make you nervous -- understandable in a week like this one -- perhaps you should consider cars.

Classic cars.

The Economist magazine put together an index of fancy collectible items: art, wine, coins, guitars. But the thing that really outperformed over time was classic cars. An index of the 50 finest Ferraris, Porsches, etc., increased by 53 percent over the past two years.

The entire "valuables index" is up more than 200 percent over the past 10 years. That's more than twice the S&P.
