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.
If investing in single stocks may be too risky for you, consider investing in good growth stock mutual funds. Mutual funds are a simple, even boring, investment plan, yet they work well for most people. Of course, all investing requires a degree of risk; there really is no sure thing. But mutual funds are a great balance of reasonable risk and excellent returns. They have built-in diversification that will keep you from putting all your eggs in one basket.

Experienced investors such as Buffett eschew stock diversification in the confidence that they have performed all of the necessary research to identify and quantify their risk. They are also comfortable that they can identify any potential perils that will endanger their position, and will be able to liquidate their investments before taking a catastrophic loss. Andrew Carnegie is reputed to have said, “The safest investment strategy is to put all of your eggs in one basket and watch the basket.” That said, do not make the mistake of thinking you are either Buffett or Carnegie – especially in your first years of investing.
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.

Some trading platforms may be agnostic to a specific intermediary or broker, while other trading platforms are only available when working with a particular intermediary or broker. As a result, investors should also consider the reputation of the intermediary or broker before committing to a specific trading platform to execute trades and manage their accounts.

If you are literally just getting started, the services offered by most major stockbrokers (information here) as a part of their trading account services will be a good place to start (and free). Firms such as Trade King, eTrade, Charles Schwab and Ameritrade provide a range of online tools. These will give you a feel for how portfolio management software works without having to pay extra to learn. However, these services typically offer no advice (known as execution only), which means that a separate service will be required for information analysis.


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.
If you’re interested in day trading, our recommendation is to allocate a small portion of your overall portfolio to the strategy – no more than 5% or 10%, tops. That way, if you lose money — as you are likely to do, at least at first — those losses are at least capped. The rest of your portfolio should be invested in long-term, diversified investments like low-cost index funds.
