"Looking at the math
Both stocks have pulled back slightly during the past month, but they still trade at what many would consider premium valuations. Visa and Mastercard sell at price-to-earnings (P/E) ratios of 31 and 38, respectively. That might discourage prospective investors who believe this greatly reduces the potential to achieve solid returns in the future. But these valuations are lower than their trailing-five-year averages.
Based on the favorable qualities I discussed above, not many people would argue that the P/E multiples Visa and Mastercard command are unwarranted. These are undoubtedly two of the best businesses on the face of the planet.
If they can keep up their impressive growth trends, their market caps have a very good shot at hitting $1 trillion by 2030. According to average of analyst estimates, Visa and Mastercard are projected to increase their earnings per share at annualized rates of 13.3% and 16.7%, respectively, during the next three years. Should that continue throughout the decade, which I believe it will, then investors have a lot to be excited about."
