There are several types of stocks that investors can buy and sell in the stock market. Some of the common types of stocks include:

1. Common Stock: This is the most common type of stock, representing ownership in a company. Common stockholders have voting rights and are entitled to a share of the company’s profits through dividends.

2. Preferred Stock: Preferred stockholders have priority over common stockholders when it comes to receiving dividends and assets in the event of bankruptcy or liquidation. However, they usually do not have voting rights.

3. Blue Chip Stocks: These are stocks of well-established companies with a strong reputation and a long history of stable earnings and dividend payments.

4. Growth Stocks: These are stocks of companies that are expected to grow at a faster rate than the overall market. These companies typically reinvest their earnings back into the business rather than paying out dividends.

5. Value Stocks: These are stocks of companies that are considered undervalued by the market and have the potential to increase in price.

6. Penny Stocks: These are stocks of small companies that trade for less than $5 per share. These stocks are considered high-risk and volatile.

7. Income Stocks: These are stocks of companies that pay out a high dividend yield to their shareholders.

It’s important to note that investing in the stock market comes with risks, and it’s important to do your own research and consult with a financial advisor before making any investment decisions.
