WSJ Financial columnist Jason Zweig makes a solid point when he writes ('What You've Lost In This Bull Market', Sept. 3, Business & Investing):
"You can’t invest at all without taking any risk. Even if you keep 100% of your money in Treasury bills backed by the U.S. government or bank accounts insured by Uncle Sam, that isn’t risk-free. You run the very real risk that, at today’s paltry interest rates, the income you earn won’t maintain its purchasing power. Net of inflation, you are highly likely to lose money.
