<human>: What is the difference between a'stock' and a'share'?
<bot>: The main difference between a stock and a share is that stocks represent ownership in a company, while shares are simply units of ownership. Stocks typically give investors voting rights and the right to receive dividends or other forms of income, while shares usually do not have these same rights. Additionally, stocks can be traded on public exchanges, while shares may only be sold by the company itself.
