A share of stock—sometimes called security or equity—is legal ownership in a business. Corporations issue stock to raise money and it comes in two varieties—common or preferred. Common stock entitles the stockholder to a proportionate share of a company's profits or losses. Preferred stock, meanwhile, comes with a predetermined dividend payment. There's more that distinguishes the two types of stock.
It is also important to know what you want to accomplish with your investments before you actually invest. For example, you might want to purchase a home, fund a child’s college education, or build an adequate retirement nest egg. If you set financial goals at the outset—and match your investments to achieve those goals—you are more likely to reach them.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
