Understanding the stock marketWhen people refer to the stock market being up or down, they’re generally referring to one of the major market indexes.
When people refer to the stock market being up or down, they’re generally referring to one of the major market indexes.A market index tracks the performance of a group of stocks, which either represents the market as a whole or a specific sector of the market, like technology or retail companies. You’re likely to hear most about the S&P 500, the Nasdaq composite and the Dow Jones Industrial Average; they are often used as proxies for the performance of the overall market.

If you plan to re-enter the market at a sunnier time, you’ll almost certainly pay more for the privilege and sacrifice part (if not all) of the gains from the rebound.

The alternative is a mutual fund, the aforementioned exchange-traded fund or an index fund. These hold a basket of investments, so you’re automatically diversified.
