The Markowitz Model is a way to help people decide how to invest their money. It helps you decide what types of investments you should buy, and how much money should you spend on each one. It uses different factors such as risk and return to figure out what the best investments are for you. It also looks at how likely it is for you to make money off each investment, and how much you might lose if the investment doesn't do well. By using this model, you can make sure you're investing your money in the best possible way.
