Many will allow you to buy ‘fractional shares,' which allows you to own portions of stock without buying an entire share. For example, some stock, like Berkshire Hathaway, or Amazon.com, can cost thousands of dollars to own just one share.

If you're looking to bet against a company, the process is more complex. You'll need access to an options trading platform, or a broker who will allow you to ‘go short' a share of stock by lending you the shares to sell.
