There are few companies in the United States that can match the legacy and success of Pfizer (NYSE:PFE), one of the nation's leading pharmaceutical companies. It's likely for this reason that Pfizer's stock is a favorite among money managers and investors. Its top five shareholders control $35.9 billion worth of its outstanding common stock, equating to an ownership interest of 17.5%.

Even though this is a sizable stake, it's relatively conservative on a percentage basis compared to other leading companies, such as AIG (NYSE:AIG) and Boeing (NYSE:BA):

  • AIG's five biggest shareholders control 19.9% of the insurance company's outstanding stock. That equates to $14.3 billion worth of AIG shares.
  • Boeing's five biggest stockholders own 29.4% of its stock. The total dollar value of their combined stake translates into $26.1 billion worth of Boeing shares.

So, who are Pfizer's five biggest shareholders? You can find the answer to this question in the brief slideshow below.
