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.
P/E ratio -- The price-to-earnings ratio is the most widely cited valuation metric, and for good reason. It's an easy way to compare similar businesses. Simply divide a company's current share price by its last 12 months' worth of earnings. You can also use the projected earnings over the next 12 months to calculate the forward P/E ratio. The key point to know is that P/E ratios are most useful when comparing businesses in the same industry -- such as comparing ExxonMobil (NYSE:XOM) and Chevron (NYSE:CVX).

An online brokerage account likely offers your quickest and least expensive path to buying stocks, funds and a variety of other investments. With a broker, you can open an individual retirement account, also known as an IRA — here are our top picks for IRA accounts — or you can open a taxable brokerage account if you’re already saving adequately for retirement elsewhere.
"Investing has become much easier," says Steve Sanders, executive vice president of marketing and new product development at Greenwich, Connecticut-based Interactive Brokers. "More of your hard-earned money will go straight toward your portfolio and not toward paying fees. I think this will be extremely helpful for beginning investors as well as others who like to save money."
Bernard Baruch, known as “The Lone Wolf of Wall Street,” owned his own seat on the New York Stock Exchange by age 30 and became of the country’s best known financiers by 1910. Mr. Baruch, while a master of his profession, had no illusions about the difficulties of successful stock market investing, saying, “The main purpose of the stock market is to make fools of as many men as possible.” According to Ken Little, author of 15 books on investing and personal finance topics, “If you are an individual investor in the stock market, you should know that the system stacks the deck in its favor.”
There are many fees an investor will incur when investing in mutual funds. One of the most important fees to consider is the management expense ratio (MER), which is charged by the management team each year, based on the number of assets in the fund. The MER ranges from 0.05% to 0.7% annually and varies depending on the type of fund. But the higher the MER, the more it impacts the fund's overall returns.
It’s likely some of these Americans might rethink pulling their money if they knew how quickly a portfolio can rebound from the bottom: The market took just 13 months to recover its losses after the most recent major sell-off in 2015. Even the Great Recession — a devastating downturn of historic proportions — posted a complete market recovery in just over five years. The S&P 500 then posted a compound annual growth rate of 16% from 2013 to 2017 (including dividends).
In late 2014, legendary self-help and business guru Tony Robbins published a book called Money: Master The Game. In it he explains the strategies and ideas used by the very best investors in the world - hedge fund managers, asset allocators and billionaires - that he gleaned from them during four years of interviews and how their lessons should be applied by the rest of us.

Some scammers will buy up a ton of some near-bankrupt, almost lifeless penny stock, then use lies and exaggerations to push the share price much higher. They might say the company is about to get some huge business deal with Google or their neighbor just struck gold in their similar mine, or they are going to land a major FDA clearance. That typically helps increase the value of the penny stock, which creates a profit for the promoter or scam artist. As the shares increase in value, they sell their holdings. These shares usually collapse back down to near-worthless status once the promoter has taken their profits and moved on. 


The most feared words on any stock exchange are margin call. A margin call is made when a position is losing money and more money is required by the broker to keep the trade open. If and when a stock ticker moves quickly, there can be people whose borrowing levels literally bankrupt them as things get worse ... fast. Volatility can be either a blessing or a curse, but if you have too much leverage, it can break a trader.


It pays to shop around some before deciding on where you want to open an account, and to check out our broker reviews. We list minimum deposits at the top of each review. Some firms do not require minimum deposits. Others may often lower costs, like trading fees and account management fees, if you have a balance above a certain threshold. Still, others may give a certain number of commission-free trades for opening an account.
E (Very Weak) - The stock has significantly underperformed most other funds given the level of risk in its underlying investments, resulting in a very weak risk-adjusted performance. Thus, its investment strategy and/or management has done just the opposite of what was needed to maximize returns in the recent economic environment. While the risk-adjusted performance of any stock is subject to change, we believe this fund has proven to be a very bad investment in the recent past.

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.

Day trading is the act of buying and selling a financial instrument within the same day or even multiple times over the course of a day. Taking advantage of small price moves can be a lucrative game—if it is played correctly. But it can be a dangerous game for newbies or anyone who doesn't adhere to a well-thought-out strategy. What's more, not all brokers are suited for the high volume of trades made by day traders. Some brokers, however, are designed with the day trader in mind. You can check out our list of the best brokers for day trading to see which brokers best accommodate those who would like to day trade.


D (Weak) - The stock has underperformed the universe of other funds given the level of risk in its underlying investments, resulting in a weak risk-adjusted performance. Thus, its investment strategy and/or management has not been attuned to capitalize on the recent economic environment. While the risk-adjusted performance of any stock is subject to change, we believe that this fund has proven to be a bad investment over the recent past.
But building a diversified portfolio of individual stocks takes a lot of time, patience and research. The alternative is a mutual fund, the aforementioned ETF or an index fund. These hold a basket of investments, so you’re automatically diversified. An S&P 500 ETF, for example, would aim to mirror the performance of the S&P 500 by investing in the 500 companies in that index.
A robo-advisor offers the benefits of stock investing, but doesn't require its owner to do the legwork required to pick individual investments. Robo-advisor services provide complete investment management: These companies will ask you about your investing goals during the onboarding process and then build you a portfolio designed to achieve those aims.

Finally, keep in mind that if trading on margin—which means you're borrowing your investment funds from a brokerage firm (and bear in mind that margin requirements for day trading are high)—you're far more vulnerable to sharp price movements. Margin helps to amplify the trading results not just of profits, but of losses as well if a trade goes against you. Therefore, using stop losses is crucial when day trading on margin.

Businesses you don't understand -- Here's a great rule of thumb that works for beginners and expert investors alike. If you can't clearly explain what a company does and how it makes money in a sentence or two, don't invest in it. There are literally thousands of publicly traded companies to choose from, and you should be able to find plenty of opportunities in easy-to-understand businesses.
Every investor should try to establish what their goals and objectives are prior to investing. There isn’t necessarily a wrong objective, but it’s more important to understand your goals because that will help drive your decisions. For instance, if you plan to regularly trade in and out of stocks, you might be better off opening an IRA account so you don’t have to pay taxes on your trades. If you plan to be a long-term investor, taxes won’t be as important of a factor and you could hold your account in a taxable or tax-free account.

By understanding your risk tolerance, you can avoid those investments which are likely to make you anxious. Generally speaking, you should never own an asset which keeps you from sleeping in the night. Anxiety stimulates fear which triggers emotional responses (rather than logical responses) to the stressor. During periods of financial uncertainty, the investor who can retain a cool head and follows an analytical decision process invariably comes out ahead.
