In this week's Barron's, Anna Raff writes the courageously bearish piece, "Why Silver Will Tarnish." What makes it courageous? Raff predicts that silver's historic rally is about to end. Among other things, Raff builds her case around the following points: Gold and silver are both "safe haven" assets, but silver has greatly outperformed gold recently. Silver prices have doubled since August, while gold is up 20% in the same span. Over just the past three months, silver has shot up 50% compared with 11% for gold. Raff doesn't trust the investment demand driving silver prices. Unlike institutional investors, the little guy is less likely to hold silver over the long run. Analysts say individuals may well trade out of precious metals and into higher-yielding assets once interest rates start to rise, as the tightening of monetary policy gains traction around the world.
