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

There are many fees an investor will incur when investing in mutual funds. One of the most important fees to focus on is the management expense ratio (MER), which is charged by the management team each year based on the amount of assets in the fund. The higher the MER, the worse it is for the fund's investors. It doesn't end there: you'll also see a number of sales charges called "loads" when you buy mutual funds.

How do I determine if a brokerage firm is right for me before I open an account? Some key criteria to consider when evaluating any investment company are how much money you have, what type of assets you intend to buy, your trading style and technical needs, how frequently you plan to transact and how much service you need. Our post about how to choose the best broker for you can help you sort through the features brokerage firms offer and rank your priorities.

Shouldn’t I just choose the cheapest broker? Trading costs definitely matter to active and high-volume traders. If you’re a high-volume trader — buying bundles of 100 to 500 shares at a time, for example — Interactive Brokers and TradeStation are cost-effective options. Ally Invest offers $3.95 trades ($1 off full price) for investors who place more than 30 trades a quarter.  Commissions are less of a factor for buy-and-hold investors, a strategy we recommend for the majority of people. Most online brokers charge from $5 to $7 per trade. But other factors — access to a range of investments or training tools — may be more valuable than saving a few bucks when you purchase shares.

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.


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.


Think win/win. Psychology is a huge aspect of trading. If you have a big winner on your hands and aren’t sure whether you should hold the shares to try for higher prices or sell them to lock in a profit, consider selling half and holding the rest with a stop loss (at worst) back at your original buy price. That way, if the stock drops back to your buy price, you still win because you sold half and made a profit. Similarly, if the stock shoot higher in price, you also win because you still hold half your original position. Heads you win, tails you win too. 🙂

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.

CAUTION – One of the most common mistakes new investors make is to buy too many shares for their first stock trade; this is a mistake. Taking on too much risk as a beginner who is just getting started will very likely result in experiencing unnecessary losses. Instead, begin with trading small position sizes, then slowly work your way up to buying more shares, on average, each trade.

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.

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.

Overall commission costs can also be affected by new customer promotions. Brokers may give you a chunk of free trades based on your deposit amount. If your deposit gets you a substantial number of free trades, that can write off otherwise higher per-commission costs. Ally Invest offers small incentives for deposits as low as $500. Fidelity Investments, meanwhile, has a higher barrier for entry — it takes a $50,000 deposit, but then you'll get 300 free trades.

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!

New investors need two things from their online stock trading platform: an easy learning curve and lots of room to grow. E*TRADE has both. Its platform boasts a library of educational videos, articles, and webinars for each type of investor. Once you’ve mastered the fundamentals, read up on market news, reports, and commentary from E*TRADE analysts. You can also take advantage of one-on-one assistance: Branch appointments are free to book, and online chat tools and 24-hour hotline are there to guide you from anywhere in the world.

In most cases, your broker will charge a commission every time that you trade stock, either through buying or selling. Trading fees range from the low end of $2 per trade but can be as high as $10 for some discount brokers. Some brokers charge no trade commissions at all, but they make up for it in other ways. There are no charitable organizations running brokerage services.

Stock mutual funds or exchange-traded funds. These mutual funds let you purchase small pieces of many different stocks in a single transaction. Index funds and ETFs are a kind of mutual fund that track an index; for example, a Standard & Poor’s 500 fund replicates that index by buying the stock of the companies in it. When you invest in a fund, you also own small pieces of each of those companies. You can put several funds together to build a diversified portfolio. Note that stock mutual funds are also sometimes called equity mutual funds.


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.

News sites such as CNBC and MarketWatch serve as a great resource for beginners. For in depth coverage, look no further than the Wall Street Journal and Bloomberg. By casually checking in on the stock market each day and reading headline stories, you will expose yourself to economic trends, third-party analysis, and general investing lingo. Pulling stock quotes on Yahoo Finance to view a stock chart, view news headlines, and check fundamental data can also serve as another quality source of exposure.

Thinkorswim is a particular standout in options trading, with options-trading tabs (just click “spread” if you want a spread and “single order” if you want one leg), plus links that explain the strategies on the order page. Its Strategy Roller feature lets investors create custom covered calls and then roll those positions from expiration to expiration.

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.

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.

In terms of diversification, the greatest amount of difficulty in doing this will come from investments in stocks. As mentioned earlier, the costs of investing in a large number of stocks could be detrimental to the portfolio. With a $1,000 deposit, it is nearly impossible to have a well-diversified portfolio, so be aware that you may need to invest in one or two companies (at the most) to begin with. This will increase your risk.

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.

Learning about great investors from the past provides perspective, inspiration, and appreciation for the game which is the stock market. Greats include Warren Buffett (below), Jesse Livermore, George Soros, Benjamin Graham, Peter Lynch, John Templeton and Paul Tudor Jones, among others. One of my favorite book series is the Market Wizards by Jack Schwager.

With cutting-edge research tools and mobile apps, online stock trading is perfect for investors who want to strike out on their own with “self-directed trading” instead of paying fees for a managed portfolio. Whether you’re a first-time investor or an expert trader, you need a trading platform that’s user-friendly, trustworthy, and packed with data visualizations. To find the best online stock trading sites of 2019, we analyzed 25 of the most popular platforms and tapped into the expertise of a former day trader, a stock analyst, and a financial commentator with more than two decades of trading experience. In short, there is no single best online stock broker, but each of our top picks has its own strengths for different types of investors. We’ll help you determine the best fit for your investment goals and experience.
