The study looked at how important it is to choose the right mix of investments for a portfolio in Zimbabwe. They found that most of the returns from a portfolio come from deciding how to divide up the money between different types of assets. Market movements also have a big impact on how well a portfolio does. But once you take out the effect of market movements, both how you divide up your money and how actively you manage your investments are equally important in determining how well your portfolio performs compared to others. The study suggests that it's crucial for fund managers and investors to first figure out a plan for how to divide up their money that matches their goals, how long they plan to invest for, and how much risk they're comfortable with.
