FYI: Evaluating the performance of actively managed mutual funds generally involves comparing a product’s results with some passive benchmark (the SEC requires that funds select a benchmark for comparison purposes) that follows the same investment “style” as the fund’s portfolio (such as the S&P 500 for large-cap stocks, the S&P MidCap 400 for midcap stocks and the S&P SmallCap 600 for small-cap stocks).
