My clients frequently ask me if they should invest in gold. Since the financial crisis in 2008, advertisements for gold have blanketed the television and radio airwaves. Many major radio and television personalities have become gold advocates (of course they're being well-paid to do so). Gold is often pitched as an inflation hedge and a defensive move against possible economic downturns. In my experience, gold is typically not a desirable investment. This is illustrated in professor Jeremy Siegel's book Stocks for the Long Run (McGraw-Hill, $40).
