While more than doubling your money might seem like a good result (it's close to $3,000 if dividends were reinvested), the performance of UPS (NYSE: UPS) and its rival FedEx (NYSE: FDX) lagged the S&P 500 over the period. To gauge the success of UPS' transformational strategy (launched in 2018), it's a good idea to look at the stock's performance on a three-, five-, and 10-year basis versus the S&P 500 and FedEx. As you can see below, UPS has notably outperformed the S&P 500 and FedEx over the last three years and held its ground versus the index in the previous five years.
