Pfizer Has the Highest-Yielding Dividend in the S&P 500. Should Investors Be Worried?

Pfizer's 7.1% dividend yield is the highest in the S&P 500, more than six times the average, raising concerns about sustainability. While the dividend currently appears safe with the company undergoing cost-cutting restructuring, earnings provide limited buffer with diluted per-share profit of $0.47 barely exceeding the quarterly dividend of $0.43. The stock trades at a low valuation of 8x estimated future earnings, potentially making it an underrated income option for investors willing to monitor it closely, though patent cliffs and future sales challenges pose risks.
