What kind of ...?
Buying stock does not make you a business owner unless you have enough accumulated wealth already to buy a majority stake, which is a ton of shares. Only the richest CEO's and executives have enough money to buy enough stock in a company to even get a seat at their table. With a few shares of stock, you really have nothing. No vote, no decision making power, not a damn thing except a bad decision that you made to gamble away your hard-earned money and the regret that comes when the market collapses. No. The quickest and best way, the only way to become a business owner is to start your own business. It's that simple.
