  Does every business have a stock?
  Does the stock market affect small businesses?
  Can a company have no stocks?
  So most small business can buy and sell stock the same way a normal person does. Where you may need to pay more attention is how your small business will be taxed on any profits you make from dividends or stock sales.

Even B2B companies could be impacted as their client base might push off investments or large purchases.
