Investing is when you allocate money in the stock market with the goal of making an income or profit. With Cash App, you can choose to invest in a variety of stocks, and exchange-traded funds (ETFs) to help diversify your investments. The stock market can go up and down on any given day, which is why some people choose to hold onto stock for the long-term, while others might buy and sell more quickly. Whatever your investment strategy might be, Cash App makes it easy to invest in your favorite companies with as little as $1.
