The first section, titled Initial Public Offering, explains that in an IPO a company divides itself into pieces called shares, which represent ownership in the company. These shares are then sold to investors as stocks. Shareholders are partial owners who can vote for the board of directors. Traditionally, shareholders received paper stock certificates, but today shares can be held electronically by brokers.

The second section, titled How Do You Make Money with Stocks, outlines two ways investors can potentially earn money. The first is dividends, when a company distributes a portion of retained earnings to shareholders. The second is capital gains, when a stock is bought, held, and later sold for a higher price. The section notes that dividends and capital gains may be taxable events. It notes that 61% of American families own shares of stock and that the total value of world equity holdings is $116.78 trillion.
