What is a stock?
A stock is a slice of ownership in a company, and when you buy a stock, its value will rise or fall in line with the value of that company.
You might hear ‘stocks’ used interchangeably with ‘shares’ but there’s a subtle difference. ‘Stocks’ refers to broad ownership – you can own stock in Apple and Tesla for example. ‘Shares’ on the other hand, refers to a specific unit of ownership in a company – you can own three Apple shares or five shares in Tesla.
