If you have a job, your employer may offer a 401k or 403b retirement plan as part of your benefits package. These accounts invest your money for retirement, but your investment options are limited to the choices provided by your employer and plan provider. If your employer doesn't offer a retirement plan, you can open an IRA on your own with your bank or brokerage company.
While most online brokers do not offer international trading, some do. Nearly every broker supports trading American depositary receipts (ADRs), which offers US investors an easy, simple way to invest in foreign companies. However, if you want to buy physical shares of an international company, then you need to do your research. Interactive Brokers is the leader in this space but is built for professionals. For casual investing, both Fidelity and Charles Schwab offer international stock trading.
Say, a U.S.-based software company is trading at a price of $100 and has a market capitalization of $5 billion. A news item comes in that the EU regulator has imposed a fine of $2 billion on the company which essentially means that 40 percent of the company’s value may be wiped out. While the stock market may have imposed a trading price range of $90 and $110 on the company’s share price, it should efficiently change the permissible trading price limit to accommodate for the possible changes in the share price, else shareholders may struggle to trade at a fair price.

Advanced exchanges such as Kraken and GDAX will allow you to do what is called « pair trading ». Pair trading allows you to trade one fiat currency against one specific cryptocurrency, or cryptocurrency against cryptocurrency. For example, you might have an USD/BTC pair (exchange US Dollars for Bitcoin), or a GBP/ZEC pair (exchange British Pounds for Zcash), or even a BTC/LTC pair (Exchange Bitcoin for Litecoin). Bear in mind however that most exchanges which handle fiat currencies do not manage a lot of cryptocurrencies, only the mainstream ones.
Phrases like “earnings movers” and “intraday highs” don’t mean much to the average investor, and in many cases, they shouldn’t. If you’re in it for the long term — with, say, a portfolio of mutual funds geared toward retirement — you don’t need to worry about what these words mean, or about the flashes of red or green that cross the bottom of your TV screen. You can get by just fine without understanding the stock market much at all.
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.
