<human>:  How does stock market works?
<bot>: The stock market works by allowing investors to buy and sell stocks, which represent a portion of ownership in a publicly-traded company. When you buy stock, you become a part-owner of the company and can make money if the price of the stock increases. Conversely, when you sell stock, you are cashing out of your ownership position and taking profits — or losses — based on the price of the stock at the time of sale.
