Building a diversified portfolio is the priority for beginners who should consider adding index funds that capture the broader market, Swope says. Mutual funds and ETFs are the easiest solutions since they own hundreds to thousands of stocks and are less volatile than individual stocks. ETFs tend to have low minimums, allowing investors to spread their first $10,000 between a few funds and gain access to a variety of areas in the market, he says.
Fees beyond trade commissions include inactivity fees (common with active trading brokers such as Interactive Brokers, Lightspeed, and TradeStation) and IRA fees for having a retirement account. While most brokers do not charge predatory fees, it’s still important to do your due diligence. Just like a bank account, stock brokers also make a portion of their profits off miscellaneous fees.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
While both terms - stock market and stock exchange - are used interchangeably, the latter term is generally a subset of the former. If one says that she trades in the stock market, it means that she buys and sells shares/equities on one (or more) of the stock exchange(s) that are part of the overall stock market. The leading stock exchanges in the U.S. include the New York Stock Exchange (NYSE), Nasdaq, and the Chicago Board Options Exchange (CBOE). These leading national exchanges, along with several other exchanges operating in the country, form the stock market of the U.S.

A local financial regulator or competent monetary authority or institute is assigned the task of regulating the stock market of a country. The Securities and Exchange Commission (SEC) is the regulatory body charged with overseeing the U.S. stock markets. The SEC is a federal agency that works independently of the government and political pressure. The mission of the SEC is stated as: "to protect investors, maintain fair, orderly, and efficient markets, and facilitate capital formation."

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.

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.
