No thanks, I’m good with making a piddly 10% in the market each year.

If you’re an active, high-volume trader who dabbles in all kinds of assets, Interactive Brokers is a great option, since you can trade just about anything without losing $5 to $7 on every transaction. The platform interface isn’t nearly as user-friendly as Robinhood’s, nor as intuitive as TD Ameritrade’s; however, if you’re the kind of investor who’d benefit the most from Interactive Brokers (i.e., an experienced one), you’ll know your way around a candlestick chart already.

The solution to both is investing in stock index funds and ETFs. While mutual funds might require a $1,000 minimum or more, index fund minimums tend to be lower (and ETFs are purchased for a share price that could be lower still). Two brokers, Fidelity and Charles Schwab, offer index funds with no minimum at all. Index funds also cure the diversification issue because they hold many different stocks within a single fund.

The best investors are in it for the long haul. Checking your account too often might make you react to the fluctuations in the market too quickly. Personal finance expert Ramit Sethi has written that you should check your investments “probably every few months, with a major review every year.” On many sites, you can also set an alert if a stock dives. Other than that, just set up a quarterly recurring appointment to check in.

Diversification is considered to be the only free lunch in investing. (If you are new to this concept, check out Introduction To Diversification, The Importance Of Diversification and A Guide To Portfolio Construction.) In a nutshell, by investing in a range of assets, you reduce the risk of one investment's performance severely hurting the return of your overall investment. You could think of it as financial jargon for "don't put all of your eggs in one basket".

That's because — get this — the wealthiest 10% of households own 84% of all stocks—and that includes pension plans, 401(k) accounts and individual retirement accounts (IRAs) as well as trust funds, mutual funds and college savings programs like 529 plans. That means 90% of American households own the remaining 16% of all stock. These sobering stats come courtesy of Edward N. Wolff, an economist at New York University, who tells the New York Times “For the vast majority of Americans, fluctuations in the stock market have relatively little effect on their wealth, or well-being, for that matter.

You'll have to do your homework to find the minimum deposit requirements and then compare the commissions to other brokers. Chances are you won't be able to cost-effectively buy individual stocks and still be diversified with a small amount of money. Given these restrictions, it's probably worth starting out on your investment journey with mutual funds. However, like all aspects of investing, it's up to you to do the research and figure out the strategy that suits you best.

Our experts suggest you begin by looking at your own life. “Buy what you know, where you are. If you can, identify good companies locally,” says Randy Cameron, a portfolio manager and investment advisor with 35 years of experience. “Look for companies you and your friends are talking about, ones with plans to go national.” As for how much time and money you need, “start with what you have,” he says. There is literally no minimum to get started, and starting with just one share is better than putting things off.

Three other common strategies you may hear traders refer to include momentum trading (buying shares of very fast growing companies and selling them for a profit before they inevitably peak in price), swing trading (using technical analysis to identify a trading range, and then buying and selling shares as the stock trades within that range), and penny stock trading (buying shares of very small companies whose stocks trade for less than $1 a share).

That's because — get this — the wealthiest 10% of households own 84% of all stocks—and that includes pension plans, 401(k) accounts and individual retirement accounts (IRAs) as well as trust funds, mutual funds and college savings programs like 529 plans.

We found Robinhood’s trading interface — both via its mobile app and its website — the most user-friendly of all candidates, making it a perfect option for the first-time trader. The design is minimalist, interactive, and easy to navigate. “Robinhood is a good fit for new investors because it offers a slick, modern app that allows you to trade efficiently,” says James Royal, a stock analyst and investing and wealth management reporter at Bankrate. “And of course, it's free, allowing you to invest money that would have otherwise gone into a broker's pocket.”

Worth noting: A 401(k) is a type of investment account, and if you’re participating in one, you may already be investing in stocks, likely through mutual funds. However, a 401(k) won’t offer you access to individual stocks, and your choice in mutual funds will likely be quite limited. Employer matching dollars make it worth contributing despite a limited investment selection, but once you’re contributing enough to earn that match, you can consider investing through other accounts.

Is it safe to buy stocks online?


TD Ameritrade offers two best-in-class platforms, designed for two different types of investors. Both platforms are free to use for any investor with a TD Ameritrade account. The web-based Trade Architect, though often in the shadow of thinkorswim, is streamlined and easy to use. It will appeal to beginning investors or anyone who prefers a simplified educational interface. Its tab-based navigation lets users flip between trading tools and account overview, plus charts, stock screeners, heat maps, and more.

CAUTION – Be careful. Many paid subscriptions marketed online, especially in social media, come from one-off traders that claim to have fantastic returns and can teach you how to be successful. 99.99% of them are a really poor investment and come with higher prices of $99 – $149 per month, or more. The worst damage though comes when you try to do what they do, invest way too much in a stock tip, and get burned when it doesn’t work out. See, Day Trading: 10 Lessons That Changed My Career.

First things first, let’s quickly define stock trading. Stock trading is buying and selling shares of publicly traded companies. Popular stocks most Americans know include Apple (AAPL), Facebook (FB), Disney (DIS), Microsoft (MSFT), Amazon (AMZN), Google (GOOGL), Netflix (NFLX), and more recently listed companies such as Uber (UBER) and Pinterest (PINS).

You'll have to do your homework to find the minimum deposit requirements and then compare the commissions to other brokers. Chances are you won't be able to cost-effectively buy individual stocks and still be diversified with a small amount of money. Given these restrictions, it's probably worth starting out on your investment journey with mutual funds. However, like all aspects of investing, it's up to you to do the research and figure out the strategy that suits you best.

John Paulson, a hedge-fund manager in New York, lead his firm to make $20 billion in profits between 2007 and early 2009. By betting heavily against first the housing market and then later financial stocks, his firm made a killing. Paulson’s success netted him a paycheck of some $4 billion, or more than $10 million a day. His funds during this time had returns of several hundred percent. These are his eight investing lessons:

Each publicly traded company lists their shares on a stock exchange. The two largest exchanges in the world are the New York Stock Exchange (NYSE) and the NASDAQ; both are based in the United States (Wikipedia). Attempting to grasp just how large the NYSE and NASDAQ both are is certainly not easy. The NYSE has a market cap of nearly $31 trillion and the NASDAQ’s is nearly $11 trillion. And yes, that is not a typo, I said, “trillion”.

Brokers are either full-service or discount. Full-service brokers, as the name implies, give the full range of traditional brokerage services, including financial advice for retirement, healthcare and everything related to money. They usually only deal with higher-net-worth clients, and they can charge substantial fees, including a percent of your transactions, a percent of your assets they manage, and sometimes a yearly membership fee. It's common to see minimum account sizes of $25,000 and up at full-service brokerages. Still, traditional brokers justify their high fees by giving advice detailed to your needs.

Take for example the S&P 500 market index, which is comprised of 505 companies. Buying shares in 505 different companies would be very difficult to do. Thanks to mutual funds and ETFs, we can simply buy one single security that holds shares in all 505 companies. The largest S&P 500 mutual fund is the Vanguard 500 Index Fund Admiral Shares (VFIAX) and the largest S&P 500 ETF is the State Street Global Advisors SPDR S&P 500 ETF (SPY).

CAUTION – Be careful. Many paid subscriptions marketed online, especially in social media, come from one-off traders that claim to have fantastic returns and can teach you how to be successful. 99.99% of them are a really poor investment and come with higher prices of $99 – $149 per month, or more. The worst damage though comes when you try to do what they do, invest way too much in a stock tip, and get burned when it doesn’t work out. See, Day Trading: 10 Lessons That Changed My Career.

Let’s take Apple (AAPL) for example, which is listed on the NASDAQ stock exchange. Apple currently has 4.6 billion shares outstanding, of which 4.35 billion are available to be traded (also known as the “float”). Using today’s closing price of $201.75 (July 11th, 2019), Apple has a market cap of $937.44 billion. That’s a big company! (By the way, market cap is a simple way to gauge the value of a company. If you bought every available share of stock, the market cap is how much it would cost you to buy the entire company.)

Like Fidelity and Vanguard, Charles Schwab is one of the older brick-and-mortar investment brokers that successfully modernized its trading platform for the Internet Age. Of all our picks, Charles Schwab is the best option for advanced traders who want a full buffet of options (stocks, ETFs, options, bonds, mutual funds, futures) and an impressive suite of research tools. Best of all, even with all the perks Charles Schwab offers, it’s still one of the lowest-cost trading platforms, with cheaper fees than E*TRADE or TD Ameritrade on most trades.

Take for example the S&P 500 market index, which is comprised of 505 companies. Buying shares in 505 different companies would be very difficult to do. Thanks to mutual funds and ETFs, we can simply buy one single security that holds shares in all 505 companies. The largest S&P 500 mutual fund is the Vanguard 500 Index Fund Admiral Shares (VFIAX) and the largest S&P 500 ETF is the State Street Global Advisors SPDR S&P 500 ETF (SPY).

Finally, the other factor: risk tolerance. The stock market goes up and down, and if you’re prone to panicking when it does the latter, you’re better off investing slightly more conservatively, with a lighter allocation to stocks. Not sure? We have a risk tolerance quiz — and more information about how to make this decision — in our article about what to invest in.

You may see a number of sales charges called loads when you buy mutual funds. Some are front-end loads, but you will also see no-load, and back-end load funds. Be sure you understand whether a fund you are considering carries a sales load prior to buying it. Check out your broker's list of no-load funds, and no-transaction-fee funds if you want to avoid these extra charges.

The most common order types: market, limit, and stop (see my guide, Best Order Types for Stock Trading). Market orders buy or sell immediately at the current best market price. Limit orders only buy or sell these shares at, “$xx price or better”. Lastly, stop loss orders are combined with a market or limit to trigger once $xx price hits. For new investors just getting started, I always suggest just sticking with market orders.

How does the stock market work for beginners?


At $4.95 per trade, with no inactivity charge and a $50 full outgoing transfer fee, Ally Invest’s fee structure is about as low as you'll find. Even though a rash of brokers dropped their commissions in 2017 to be competitive with Ally Invest’s $4.95 flat rate, Ally keeps its edge with a zero account minimum and enticing discount for active investors — equity trades drop to $3.95 for users with 30-plus trades each quarter or a balance of $100,000.

Should you sell these five stocks, you would once again incur the costs of the trades, which would be another $50. To make the round trip (buying and selling) on these five stocks would cost you $100, or 10% of your initial deposit amount of $1,000. If your investments do not earn enough to cover this, you have lost money by just entering and exiting positions.

Since 2013, Reviews.com has helped more than 1.4 million people find the best online stock trading site for their needs. After investigating 25 major brokers and consulting three third-party financial experts, we’ve continued updating this review every month over the last five years to ensure it stays fresh. The author of this review does not own stock in any of the brokerage firms mentioned here, or in any other financial service companies.


That’s because there are plenty of tools available to help you. One of the best is stock mutual funds, which are an easy and low-cost way for beginners to invest in the stock market. These funds are available within your 401(k), IRA or any taxable brokerage account. An S&P 500 fund, which effectively buys you small pieces of ownership in 500 of the largest U.S. companies, is a good place to start.


Robo-advisors like Wealthsimple, Wealthfront, and Betterment use algorithms to determine your investment strategy. You just plug in your time frame and risk tolerance and their computers do the rest. And because they’re targeted for a younger crowd, fees are rock bottom. Wealthsimple and Betterment both have no account minimum, while Wealthfront requires $500. Wealthsimple charges an annual 0.5% advising fee; Wealthfront and Betterment charge just 0.25%.

We found Robinhood’s trading interface — both via its mobile app and its website — the most user-friendly of all candidates, making it a perfect option for the first-time trader. The design is minimalist, interactive, and easy to navigate. “Robinhood is a good fit for new investors because it offers a slick, modern app that allows you to trade efficiently,” says James Royal, a stock analyst and investing and wealth management reporter at Bankrate. “And of course, it's free, allowing you to invest money that would have otherwise gone into a broker's pocket.”

While E*TRADE’s baseline fees are a little high ($6.95 for stocks/ETFs, $6.95 plus 75 cents per contract for options) compared to Ally Invest, Charles Schwab, and Fidelity, E*TRADE does offer volume discounts. If you make more than 30 stock/ETFs trades per quarter, the fee drops to a very competitive $4.95, and if you trade more than 30 options per quarter, the contract fee goes down to 50 cents. That makes E*TRADE a good fit for active traders who keep a close eye on the market.

Now, imagine that you decide to buy the stocks of those five companies with your $1,000. To do this you will incur $50 in trading costs, which is equivalent to 5% of your $1,000. If you were to fully invest the $1,000, your account would be reduced to $950 after trading costs. This represents a 5% loss, before your investments even have a chance to earn a cent!

Let’s take Apple (AAPL) for example, which is listed on the NASDAQ stock exchange. Apple currently has 4.6 billion shares outstanding, of which 4.35 billion are available to be traded (also known as the “float”). Using today’s closing price of $201.75 (July 11th, 2019), Apple has a market cap of $937.44 billion. That’s a big company! (By the way, market cap is a simple way to gauge the value of a company. If you bought every available share of stock, the market cap is how much it would cost you to buy the entire company.)

The 2010s have been a boom era for online stock brokers. According to Statista, between 10% and 15% of all U.S. adults used an online broker at least once in 2018. While some major brokerages have remained the same (Charles Schwab), others have gone through mergers and acquisitions (E*TRADE acquired OptionsHouse; TD Ameritrade and Scottrade merged; TradeKing is now Ally Invest), and a new generation of millennial-focused brokers (like Robinhood and Acorns) has kept the old guard on its toes by lowering commission rates and minimum deposits. After digging into 25 trading platforms, here are the factors that set our top picks apart from the crowd.

What should I invest my money in?


TD Ameritrade has been a powerful player in the online stock trading ecosystem for years. The flipside to such robust platforms? Cost. Even though TD Ameritrade lowered its fees in 2017 from $9.99 to $6.95, pretty much every other major discount broker slashed its prices, too. TD Ameritrade remains one of the more expensive options out there, even with more than 100 commission-free ETFs. Though its pricing structure is more expensive than those of some of the other discount brokers, there are many traders who think it's a best-in-class trading platform.

Worth noting: A 401(k) is a type of investment account, and if you’re participating in one, you may already be investing in stocks, likely through mutual funds. However, a 401(k) won’t offer you access to individual stocks, and your choice in mutual funds will likely be quite limited. Employer matching dollars make it worth contributing despite a limited investment selection, but once you’re contributing enough to earn that match, you can consider investing through other accounts.

If you want to trade “futures” (agreements to buy or sell assets in the future), Ally Invest isn’t an option. That’s not unusual for an online stock broker — neither Robinhood, Vanguard, nor Fidelity offer futures trading — but you can do it with some of our other top picks, including E*TRADE, Charles Schwab, Interactive Brokers, and TD Ameritrade.

We evaluated brokerage firms and investment companies on the services that matter most to different types of investors. For example, for active traders, we note online brokers offering volume discounts on trade commissions and robust mobile trading platforms. For people venturing into investing for the first time, we call out the best online brokers for educational support (such as stock-picking tutorials) and on-call chat or phone support.

Give yourself a few thousand in fake money and play investor for a bit while you get the hang of it. “Just start. Even with just a virtual portfolio. Start and then commit to building over time,” says Jane Barratt, CEO of investment education and advisory company GoldBean. “Don’t expect anything major to happen in a short time — build your money muscles by taking risks in a virtual portfolio.” To experiment with trading before getting your feet wet with real money, try TD Ameritrade's paperMoney, a virtual trading platform.

In addition to attractive pricing, Ally offers a quality platform that gives you access to the entire universe of stocks and ETFs. Where some discount brokers focus on only one kind of trader (for example, options traders or high-net-worth investors), Ally Invest provides an excellent experience for investors of all kinds. A focus on discounted costs can sometimes be a red flag for quality, but Ally truly delivers with sophisticated calculators, profit-loss estimators, and more. Ally also offers a robust research library that incorporates visual slides and interactive media into its market data.

Stock investing is filled with intricate strategies and approaches, yet some of the most successful investors have done little more than stick with the basics. That generally means using funds for the bulk of your portfolio — Warren Buffett has famously said a low-cost S&P 500 index fund is the best investment most Americans can make — and choosing individual stocks only if you believe in the company’s potential for long-term growth.

How much money should I invest in stocks? If you’re investing through funds — have we mentioned this is our preference? — you can allocate a fairly large portion of your portfolio toward stock funds, especially if you have a long time horizon. A 30-year-old investing for retirement might have 80% of his or her portfolio in stock funds; the rest would be in bond funds. Individual stocks are another story. We’d recommend keeping these to 10% or less of your investment portfolio.

Warren Buffett is the best example to hit this point home. In 2008, he bet some hedge fund managers $1 million that they wouldn’t be able to make more money in a decade than a cheap, boring index fund. An index fund uses simple investing algorithms to track an index and doesn’t require active human management. Conversely, hedge funds stack management fees on top of trading fees to pay for the time and knowledge actual strategists are putting into your investments.

That’s because there are plenty of tools available to help you. One of the best is stock mutual funds, which are an easy and low-cost way for beginners to invest in the stock market. These funds are available within your 401(k), IRA or any taxable brokerage account. An S&P 500 fund, which effectively buys you small pieces of ownership in 500 of the largest U.S. companies, is a good place to start.

Diversification is considered to be the only free lunch in investing. (If you are new to this concept, check out Introduction To Diversification, The Importance Of Diversification and A Guide To Portfolio Construction.) In a nutshell, by investing in a range of assets, you reduce the risk of one investment's performance severely hurting the return of your overall investment. You could think of it as financial jargon for "don't put all of your eggs in one basket".

Paying for research and trade ideas can be educational. Some investors may find watching or observing market professionals to be more beneficial than trying to apply newly learned lessons themselves. There are a variety of paid subscription sites available across the web; the key is to find the right one for you. Here’s a list of the services I use myself. Two of the most well-respected subscription services are Investors.com and Morningstar.

Fidelity’s platform wins for user-friendly design, with tools to help take the guesswork out of finding funds and nosing out strategies. Fidelity’s platform lets you explore your options with a slick and intuitive design, complete with color-coded rankings and charts that call out what’s important. You can sort stocks by size, performance, and even criteria like sales growth or profit growth. Want to sort ETFs by the sectors they focus on or their expenses? Done. There’s even a box to check if you want to explore only Fidelity’s commission-free offerings. A few other discount brokers do offer screeners, but none match Fidelity’s depth and usability.

Important legal information about the email you will be sending. By using this service, you agree to input your real email address and only send it to people you know. It is a violation of law in some jurisdictions to falsely identify yourself in an email. All information you provide will be used by Fidelity solely for the purpose of sending the email on your behalf. The subject line of the email you send will be "Fidelity.com: "

To keep costs as low as possible, famous investors like John Bogle and Warren Buffett recommend buying and holding the entire stock market. Known as passive investing, it is a buy and hold strategy where you buy an entire market index, typically the S&P 500, as a single mutual fund or exchange traded fund (ETF). By buying an entire index, you are properly diversified (have shares in ~500 large companies, not just one), which reduces your risk long term. In fact, John Bogle is credited with creating the first index fund.

A mentor could be a family member, a friend, a coworker, a past or current professor, or any individual that has a fundamental understanding of the stock market. A good mentor is willing to answer questions, provide help, recommend useful resources, and keep spirits up when the market gets tough. All successful investors of the past and present have had mentors during their early days.

CAUTION – Like paid subscriptions, be very careful with classes and courses. Most are easily over $1,000 and are sold with promises of acquiring valuable knowledge. Their fantastic sales funnels will suck you in, take your money, excite you during the course, then leave you with a strategy that was profitable five or ten years ago, but is no longer relevant today. That, or you simply do not yet have the expertise required to be successful and trade the strategy properly.

The solution to both is investing in stock index funds and ETFs. While mutual funds might require a $1,000 minimum or more, index fund minimums tend to be lower (and ETFs are purchased for a share price that could be lower still). Two brokers, Fidelity and Charles Schwab, offer index funds with no minimum at all. Index funds also cure the diversification issue because they hold many different stocks within a single fund.

In the stock market, for every buyer, there is a seller. When you buy 100 shares of stock, someone is selling 100 shares to you. Similarly, when you go to sell your shares of stock, someone has to buy them. If there are more buyers than sellers (demand), then the stock price will go up. Conversely, if there are more sellers than buyers (too much supply), the price will fall.
