yep was just going to answer that:
5% / Insider Ownership
Shares held by insiders or individuals and institutions owning 5% or more of the total number of outstanding shares is known as 5% or Insider Ownership. A five percent stake in any large company is significant, and large companies typically don't have such shareholders.
That being said, there are 5% ownership positions held by individuals and institutions. At one time, Bill Gates owned about 5% of the outstanding shares of Microsoft. The investment firm of Berkshire Hathaway owns about 8% of Coca Cola's outstanding shares.
Stock Float
The term "float" is used in many different ways, but when used to describe stock ownership, float refers to the percentage of outstanding shares that are not owned by insiders of the corporation. http://www.money-zine.com/investing/investing/understanding-stock-ownership/
