1 Once upon a time, when you bought broccoli you bought the whole vegetable, stems and crowns. Then it became customary for grocery store produce departments to separate the crowns from the stems and to sell the crowns at a premium. 2  Iâm not a fan of this practice, because I like both parts of the broccoli plant.
A company's first issue of common stock to the public is called an Initial Public Offering. Afterwards, a corporation may issue new equity at any time in order to finance its growth. When new common shares are offered to existing shareholders first, this is called a rights offering.
If the issuing company grows their sales and increases profits, investors may buy more of the stock. If the stock price goes up, you can sell your shares for a gain. For example, imagine that you buy 100 shares of stock priced at $15 each. That's a $1,500 investment. After two years, the stock price increases to $20.
