If you knew (or thought) a bear market in stocks was just around the corner, would you prefer to be invested in 100% stocks or 100% bonds? Since the S&P 500 lost over 50% in the last two bear markets (2000-2002 and 2007-2009), the answer is easy. Therefore, we can learn something about the market’s tolerance for risk by monitoring the ratio of stocks to bonds.
