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.
The most recent annual report – While reading the annual report, you'll want to pay special attention to the letter from the Chairman, CEO, and sometimes CFO or other high-ranking officers to see how they view the business. Not all annual reports are created equally. Generally, the best in the business is considered to be the one written by Warren Buffett at Berkshire Hathaway, which you can download from free on the holding company's corporate site.
When it comes to research, Fidelity is in a league of its own. The intellectually curious can dive into research from more than 20 providers, including Recognia, Ned Davis, and McLean Capital Management. Fidelity’s Learning Center featured videos are organized by topic, but they don’t stop after explaining the concept; they also cover how to apply principles to your own Fidelity investments.

It's crucial to educate yourself before you wade into any type of investment or investment strategy. This beginner's guide to online stock trading will give you a starting point and walk you through several processes: choosing a discount broker, the 12 types of stock trades you can make, how to select individual stocks, uncovering hidden fees, expenses, and commissions, and much more. 
While E*TRADE’s baseline fees are a little high ($6.95 for stocks/ETFs, $6.95 plus 75 cents per contract for options) compared to Ally Invest, Charles Schwab, and Fidelity, E*TRADE does offer volume discounts. If you make more than 30 stock/ETFs trades per quarter, the fee drops to a very competitive $4.95, and if you trade more than 30 options per quarter, the contract fee goes down to 50 cents. That makes E*TRADE a good fit for active traders who keep a close eye on the market.

Unlike most online stock trading platforms, Robinhood doesn’t charge a commission fee every time you buy or sell stocks, ETFs, or options. If you’re a high-volume trader, or a beginner without much cash to spare, that makes Robinhood an attractive alternative to the $5 to $7 fees per trade offered by competitors. However, Robinhood does rake in “payment for order flow” by rounding regulatory fees up to the nearest penny and pocketing the difference. “That means if you buy a stock for $100.00, Robinhood earns 2.6 cents from the market maker,” says co-founder and co-CEO Vlad Tenev, whereas “other brokerages earn rebates and charge you a per-trade commission fee.”
Thinkorswim is a particular standout in options trading, with options-trading tabs (just click “spread” if you want a spread and “single order” if you want one leg), plus links that explain the strategies on the order page. Its Strategy Roller feature lets investors create custom covered calls and then roll those positions from expiration to expiration.

Choose your trading partner wisely. To trade stocks you need a broker, but don’t just fall for any broker. Pick one with the terms and tools that best align with your investing style and experience. A higher priority for active traders will be low commissions and fast order execution for time-sensitive trades (like our picks for best online platforms for active traders/day traders). Investors who are new to trading should look for a broker that can teach them the tools of the trade via educational articles, online tutorials and in-person seminars (see NerdWallet’s round-ups for the best brokers for beginners). Other features to consider are the quality and availability of screening and stock analysis tools, on-the-go alerts, easy order entry and customer service.
Ignore “hot tips.” WallStreetHotShot4721 on the EZMillion$Trade forum and the folks who pay for sponsored ads touting sure-thing stocks are not your friends, mentors or bona fide Wall Street gurus. In many cases, they are part of a pump-and-dump racket where shady folks purchase buckets of shares in a little-known, thinly traded company (often a penny stock) and hit the internet to hype it up. As unwitting investors load up on shares and drive the price up, the crooks take their profits, dump their shares and send the stock careening back to earth. Don’t help them line their pockets. If you’re looking for a guru, bookmark Warren Buffett’s annual letters to shareholders for commonsense advice and observations on sane, long-term investing.
Robo-advisors like Wealthsimple, Wealthfront, and Betterment use algorithms to determine your investment strategy. You just plug in your time frame and risk tolerance and their computers do the rest. And because they’re targeted for a younger crowd, fees are rock bottom. Wealthsimple and Betterment both have no account minimum, while Wealthfront requires $500. Wealthsimple charges an annual 0.5% advising fee; Wealthfront and Betterment charge just 0.25%.

Paying for research and analysis can be both educational and useful. Some investors may find watching or observing market professionals to be more beneficial than trying to apply newly learned lessons themselves. There are a slew of paid subscription sites available across the web, the key is in finding the right ones for you. View a list of the services I use myself. Two well-respected services include Investors.com and Morningstar.
Stock mutual funds or exchange-traded funds. These mutual funds let you purchase small pieces of many different stocks in a single transaction. Index funds and ETFs are a kind of mutual fund that track an index; for example, a Standard & Poor’s 500 fund replicates that index by buying the stock of the companies in it. When you invest in a fund, you also own small pieces of each of those companies. You can put several funds together to build a diversified portfolio. Note that stock mutual funds are also sometimes called equity mutual funds.
