What is the cheapest way to buy stocks?

The cheapest way to buy stocks is typically through a discount brokerage that offers low or no commission fees for trades. Many online platforms now allow investors to buy fractional shares, making it more affordable to invest in expensive stocks. Additionally, consider using a robo-advisor, which often charges lower fees compared to traditional financial advisors and can help build a diversified portfolio. Always compare fees and services before selecting a brokerage to minimize costs.
