Since March 2009, the S&P 500 has surged by nearly 60% and US Treasuries have continued to surge, pushing yields close to all-time lows. This has elicited sighs of relief from professional investors, who see the strength as sure signs of recovery. Yet, these investors are ignoring - willfully or otherwise -- the very thin trading volume upon which this rally is built. Retail investors remain scarred by the '08 collapse and have steered clear of the stock market altogether. Instead, they have parked cash in the Treasury market (hence the low yields).
