Investments: The components of retirement plans that make them work for you

Stocks: Common stock is a security that represents ownership in a corporation. Holders of common stock exercise control by electing a board of directors and voting on corporate policy. Common stockholders are on the bottom of the priority ladder for ownership structure; in the event of liquidation, common shareholders have rights to a company’s assets only after bondholders, preferred shareholders and other debtholders are paid in full.

Bonds: A bond is a debt investment in which an investor loans money to an entity (typically corporate or governmental) which borrows the funds for a defined period of time at a variable or fixed interest rate. Bonds are used by companies, municipalities, states and sovereign governments to raise money and finance a variety of projects and activities. Owners of bonds are debtholders, or creditors, of the issuer.

Mutual Fund: A collection of stocks, bonds, or other securities purchased and managed by an investment company with funds from a group of investors. The return and principal value of mutual funds fluctuate with changes in market conditions. Shares when sold, or redeemed, may be worth more or less than their original cost.

Exchange Traded Fund: An ETF, or exchange-traded fund, is a marketable security that tracks an index, a commodity, bonds, or a basket of assets like an index fund. Unlike mutual funds, an ETF trades like a common stock on a stock exchange. ETFs experience price changes throughout the day as they are bought and sold.

Target-Date Fund: A mutual fund in the hybrid category that automatically resets the asset mix of stocks, bonds and cash equivalents in its portfolio according to a selected time frame that is appropriate for a particular investor. A target-date fund is similar to a life-cycle fund except that a target-date fund is structured to address some date in the future, such as retirement. Its returns are not guaranteed, but depend on how the market performs.
