Answer:
Maybe.
Step-by-step explanation:
There are a lot factors that go into being able to purchase stocks - but the primary one would be how much money do you have to invest? I'm not sure if the question is asking if you can purchase shares of stock in 100 different companies or if you can purchase 100 shares of one company's stock. Generally speaking, in addition to the cost of the stock, you also have to pay fees in order to purchase (and sell) the stock...but these days it's somewhat possible to avoid the purchase fees with a no fee stock broker...for instance Robinhood. If you want to purchase 100 shares of stock, you need to have the money to afford to purchase it...and you also need to be old enough to open an account with a brokerage service, and you need to not work in certain industries.
