For those not blessed with clairvoyance, we’ve developed an asset selection strategy that’s done very well, historically, compared to the “naïve” AANA Portfolio and even against the almighty S&P 500. We’re not implying that investors dump their valuation models, economic forecasts, or their intuition. But they should recognize that price momentum tends to persist—not just among stocks and industry groups—but at the asset-class level as well.
