I recommend that investors review their portfolios once a month. This is a good way to keep yourself on track, and it ensures that you're not neglecting your investments. It's also a good way to see how your portfolio is doing over time, so you can see if any changes need to be made to how you invest your money.
In real life, I think my recommendation is true because in the current economic climate, it's really important that people have a good idea of where their finances stand at all times. This allows them to make better decisions about what they should do with their money and how much risk they're willing to take on in order for them to reach their financial goals.
