The stock IS the company.
Since you are an owner of the company, the members of the board of directors work for you. Each year there is an election and you can vote for the board positions, one vote for each share that you own.
If you don't think the present board members are running your company properly, vote them out. You can inform the board of your ideas, concerns or recommendations and these carry the weight of your shares.
If you own 51% of the shares then your votes always win.
. .
You are the majority owner of the stock but not THE sole owner. But what you will occasionally hear on the news is some guy like Carl Icahn buying out some company or The Blackstone group or some other company to take the company private. Someone who hypothetically like you who owned the majority of stock would be able to decide whether you would allow this offer to buy "your" company or not as the other owners are somewhat meaningless because they don't own a majority, you do.
Okay, so if I own more than half the stock in a company, do I own that company? (hypothetically assuming: I may have inherited a great sum of these in several companies, and in some own more than 3/4ths of a companies entire stock)
