Shareholders and stakeholders are essentially the same things, but the term "shareholders" is a bit more specific; it refers to the shares you hold in a company. A "stake" can refer to any sort of interest in the well-being of the company. A "share" is a specific investment tool, and each share represents the same percentage of ownership in the company. If there are 100 shares in existence, for example, then each share is worth exactly 1% of the company.
