Diversify your portfolio to make sure that you don’t have too much exposure to one sector. This will help lessen your risks. Make sure to ease into your positions. You don’t need to invest all your money at once, and by easing in, you cost-average your position. Understand that investing in the market is a long-term strategy and historically, with time, the market goes up.
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.
ECN/Level 2 quotes: ECNs, or electronic communication networks, are computer-based systems that display the best available bid and ask quotes from multiple market participants and then automatically match and execute orders. Level 2 is a subscription-based service that provides real-time access to the Nasdaq order book composed of price quotes from market makers registering every Nasdaq-listed and OTC Bulletin Board security. Together, they can give you a sense of orders being executed in real time.
Buy “the basket”: Can’t decide which of the companies in a particular industry will be the long-term winner? Buy ’em all! Buying a basket of stocks takes the pressure off picking “the one.” Having a stake in all the players that pass muster in your analysis means you won’t miss out if one takes off, and you can use gains from that winner to offset any losses. This strategy will also help you identify which company is “the one” so you can double down on your position if desired.
What would make me sell: Sometimes there are good reasons to split up. For this part of your journal, compose an investing prenup that spells out what would drive you to sell the stock. We’re not talking about stock price movement, especially not short term, but fundamental changes to the business that affect its ability to grow over the long term. Some examples: The company loses a major customer, the CEO’s successor starts taking the business in a different direction, a major viable competitor emerges, or your investing thesis doesn’t pan out after a reasonable period of time.
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.

In contrast, professional fund managers (information here) do not want tips. They have dozens of good ideas of their own. They won't be sharing those ideas with you and they will not be expecting you to share yours. Instead, they ask about how you allocate money. "Which sectors and markets do you like and why?" The difference between these approaches is like night and day.

It depends. 24/7 support is essential to some investors, while others may be completely fine using online chat during regular market hours or receiving an email back within one business day. That said, most investors neglect to think about a market crisis like a flash crash. In our experience, it certainly doesn't hurt to have reliable customer service available for whenever the need may arise.

Futures, foreign currency and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one’s financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

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.)
