Growth stocks: Shares of fast-growing, higher-risk companies. They offer a higher chance of higher returns and a higher chance of bankruptcy.
Tech stocks: Shares of technology companies. Like growth stocks, they are generally riskier than other types of companies, but they also offer a chance at very high returns.
Small-cap, mid-cap and large-cap stocks: Stocks from small, mid-size and large companies. The "cap" is short for capitalization, which is simply the number of shares outstanding times the current price per share. It's important to note that a company's stock can fall into more than one category. Large-cap stocks can be blue-chip stocks, growth stocks or income stocks, for example. Small-cap stocks can be growth stocks, income stocks or tech stocks.
