When selecting a new online broker, the first step is to read reviews and see what features matter most to you. Are low-cost trade commissions most important? What about customer service, the trading platform, mobile app, investment research, ease of use, or education? With many brokers specializing in different areas, it is crucial to evaluate all categories by reading full-length broker reviews.
Understand the risks associated with the stocks you are investing in. In the company’s 10-K, there is an extensive section that talks about the company’s risks. You also need to understand your own tolerance for risk. If you invest in a stock that is highly volatile and you are not comfortable with market fluctuation, owning the investment will make you anxious and more likely to sell when it does not make sense strategically.

Dollar-cost average: This sounds complicated, but it’s not. Dollar-cost averaging means investing a set amount of money at regular intervals, such as once per week or month. That set amount buys more shares when the stock price goes down and fewer shares when it rises, but overall, it evens out the average price you pay. Some online brokerage firms let investors set up an automated investing schedule.
The list of stock brokerage firms is updated throughout the year. TradeMonster, MB Trading and Scottrade were removed from the table above, since they got acquired and merged into Etrade, Ally Invest and TD Ameritrade respectively. In addition to keeping stock brokerage companies list current we also update broker's rating and pricing, which are often correlated.
When you buy a stock, you should have a good reason for doing so and an expectation of what the price will do if the reason is valid. At the same time, you should establish the point at which you will liquidate your holdings, especially if your reason is proven invalid or if the stock doesn’t react as expected when your expectation has been met. In other words, have an exit strategy before you buy the security and execute that strategy unemotionally.

Stock brokers are people or firms licensed to buy and sell stocks and other securities via the stock market exchanges. Back in the day, the only way for individuals to invest directly in stocks was to hire stock brokers to place trades on their behalf. But what was once a clunky, costly transaction conducted via landline telephones now takes place online in seconds, for a fraction of what full-service brokers used to charge for the service. Today, most investors place their trades through an online brokerage account. (A little lost? Check out our explainers on brokerage accounts and buying stocks.)
Pooled Funds – With this type of account your capital goes into a mutual fund along with other traders’ capital. The returns will then be distributed between the investors. Normally, brokers divide these accounts according to risk appetite. For example, those looking for large returns may put their funds into a pooled account with a high risk/reward ratio. Those looking for more consistent profits would probably opt for a safer fund. Minimum investments for pooled accounts are around $2000.

Leverage simply means the use of borrowed money to execute your stock market strategy. In a margin account, banks and brokerage firms can loan you money to buy stocks, usually 50% of the purchase value. In other words, if you wanted to buy 100 shares of a stock trading at $100 for a total cost of $10,000, your brokerage firm could loan you $5,000 to complete the purchase.

In the professional world, one of the key concepts is diversification. Harry Markowitz is a Nobel prize winning economist and one of his major discoveries was that adding new asset classes can dramatically alter the overall risk profile of a portfolio. His finding was that a portfolio that contained very low risk assets would normally benefit from lower volatility and higher returns if a higher risk asset was added. This is due to the likely lack of correlation between high and low risk asset classes.
Interactive Brokers (IBKR) earns this award due to its wealth of tools for sophisticated investors and its wide pool of assets and markets. The firm makes a point of connecting to as many electronic exchanges as possible. You can trade equities, options, and futures around the world and around the clock. Interactive Brokers’ order execution engine stays on top of changes in market conditions to re-route all or parts of your order to achieve optimal execution, attain price improvement, and maximize any possible rebate. The order routing algorithms seek out a speedy execution and can access hidden institutional order flows (dark pools) to execute large block orders. The wide array of order types include a variety of algorithms as well as conditional orders such as one-cancels-another and one-triggers-another. You can also set up conditional orders based on price, volume, daily P&L, margin cushion, number of shortable shares available, rebate available from the trading venue, and other factors.
Accept losses – When you’re making so many trades every day, you’re bound to lose sometimes. It’s how you respond to those loses that defines your trading career. The loss trigger can quickly result in revenge trading, micro-managing and just flat out poor decisions. Instead, embrace small losses and remember you’re doing the correct thing, which is sticking to risk management.
It is also important to know what you want to accomplish with your investments before you actually invest. For example, you might want to purchase a home, fund a child’s college education, or build an adequate retirement nest egg. If you set financial goals at the outset—and match your investments to achieve those goals—you are more likely to reach them.
Interactive Brokers is the best broker for international trading by a significant margin. Interactive Brokers allows investors to access 125 exchanges in 31 countries across the globe. This reach is combined with a massive inventory of assets and 60 different order types to plan your entry and exit from a position. Investors can also fund their account in their domestic currency and IBKR will handle the conversion at market rates when you want to buy assets denominated in a non-domestic currency. And, if all that were not enough, the quality of trading tools available through Traders Workstation (TWS) make it easy to execute multi-layered trades across international borders. Interactive Brokers has won this category two years running, and there is no sign of that changing in the near future.
A trading platform is the software that enables investors and traders to place trades and monitor accounts through financial intermediaries. Oftentimes, trading platforms will come bundled with other features, such as real-time quotes, charting tools, news feeds, and even premium research. Platforms may also be specifically tailored to specific markets, such as stocks, currencies, options, or futures markets.
