There are different options available: you can go to a brokerage firm (sometimes also called a wirehouse or custodian) such as Fidelity, Charles Schwab or TD Ameritrade. You can open an account on the website of one of these institutions, or visit a local branch and choose to direct the investments on your own or pay to work with a staff advisor. You can also go directly to a fund company such as Vanguard, Fidelity, or T. Rowe Price and let them be your broker. They will offer you their own funds, of course, but many fund companies (such as the three just named) offer platforms on which you can buy the funds of other companies, too. See below for additional options in finding an advisor.  Always be mindful of fees and minimum-investment rules before opening an account. Brokers all charge fees per trade (ranging from $4.95 to $10 generally), and many require a minimum initial investment (ranging from $500 to much higher). Online brokers with no minimum initial-investment requirement include Capital One Investing, TD Ameritrade, First Trade, TradeKing, and OptionsHouse.   If you want more help with your investing, there is a variety of ways to find financial advice: if you want someone who helps you in a non-sales environment, you can find an advisor in your area at one of the following sites: letsmakeaplan.org, www.napfa.org, and garrettplanningnetwork.com. You can also go to your local bank or financial institution. Many of these charge higher fees, however, and may require a large opening investment. Some advisors (like Certified Financial Planners™) have the ability to give advice in a number of areas such as investments, taxes and retirement planning, while others can only act on a client's instructions but not give advice, It's also important to know that not all people who work at financial institutions are bound to the "fiduciary" duty of putting a client's interests first. Before starting to work with someone, ask about their training and expertise to make sure they are the right fit for you. as soon in your working career as possible. If you're earning taxable income and you're at least 18, you can establish a Roth IRA. This is a retirement account to which you can contribute up to an IRS-determined maximum each year (the latest limit is the lesser of $5,500 or the amount earned plus an additional $1,000 "catch up" contribution for those age 50 or older). This money gets invested and begins to grow. A Roth IRA can be a very effective way to save for retirement.   You don't get a tax deduction on the amount you contribute to a Roth, as you would if you contributed to a traditional IRA. However, any growth on top of the contribution is tax-free and can be withdrawn without penalty after you turn age 59½ (or earlier if you meet one of the exceptions to the age 59½ rule).   Investing as soon as possible in a Roth IRA is important. The earlier you begin investing, the more time your investment has to grow. If you invest just $20,000 in a Roth IRA before you're 30 years old and then stop adding any more money to it, by the time you're 72 you'll have a $1,280,000 investment (assuming a 10% rate of return). This example is merely illustrative. Don't stop investing at 30. Keep adding to your account. You will have a very comfortable retirement if you do. How can a Roth IRA grow like this? By compound interest. The return on your investment, as well as reinvested interest, dividends and capital gains, are added to your original investment such that any given rate of return will produce a larger profit through accelerated growth. If you are earning an average compound annual rate of return of 7.2%, your money will double in ten years. (This is known as "the rule of 72.") You can open a Roth IRA through most online brokers as well as through most banks. If you are using a self-directed online broker, you will simply select a Roth IRA as the type of account while you are registering. . A 401(k) is a retirement-savings vehicle into which an employee can direct portions of his or her paychecks and receive a tax deduction in the year of the contributions. Many employers will match a portion of these contributions, so the employee should contribute at least enough to trigger the employer match. From 1925 to 2011, stocks outperformed bonds in every rolling 25-year period. While this may sound appealing from a return standpoint, it entails volatility, which can be worrisome. Add less-volatile bonds to your portfolio for the sake of stability and diversification. The older you get, the more appropriate it becomes to own bonds (a more conservative investment). Re-read the above discussion of diversification. An index fund is a mutual fund that invests in a specific list of companies of a particular size or economic sector. Such a fund performs similarly to its index, such as the S&P 500 index or the Barclays Aggregate Bond index.  Mutual funds come in different shapes and sizes. Some are actively managed, meaning there is a team of analysts and other experts employed by the fund company to research and understand a particular geographical region or economic sector. Because of this professional management, such funds generally cost more than index funds, which simply mimic an index and don't need much management. They can be bond-heavy, stock-heavy, or invest in stocks and bonds equally. They can buy and sell their securities actively, or they can be more passively managed (as in the case of index funds). Mutual funds come with fees. There may be charges (or "loads") when you buy or sell shares of the fund. The fund's "expense ratio" is expressed as a percentage of total assets and pays for overhead and management expenses. Some funds charge a lower-percentage fee for larger investments. Expense ratios generally range from as low as 0.15% (or 15 basis points, abbreviated "BPS") for index funds to as high as 2% (200 BPS) for actively managed funds. There may also be a "12b-1" fee charged to offset a fund's marketing expenses. The U.S. Securities and Exchange Commission states that no evidence exists that higher-fee mutual funds produce better returns than do lower-fee funds. In other words, deal with lower-fee funds. Mutual funds can be purchased through nearly any brokerage service. Even better is to purchase directly from a mutual fund company. This avoids brokerage fees. Call or write the fund company or visit their website. Opening a fund account is simple and easy. See Invest in Mutual Funds. Exchange-traded funds (ETFs) are very similar to mutual funds in that they pool people's money and buy many investments. There are a few key differences:   ETFs can be traded on an exchange throughout the business day just like stocks, whereas mutual funds are bought and sold only at the end of each trading day. ETFs are typically index funds and do not generate as much in the way of taxable capital gains to pass on to investors as compared with actively managed funds. ETFs and mutual funds are becoming less distinct from each other, and investors need not own both types of investment. If you like the idea of buying and selling fund shares during (rather than at the end of) the trading day, ETFs are a good choice for you.
