Your investment portfolio should always reflect your financial plan for the present and future. It should also pair with your investment style, whether you welcome risk or you are risk-averse. As your plans change, your investment portfolio should change as well. It is important to do a full review at the start of each year to check for changes in the market. Then, you can adjust accordingly.
Most financial planning tips also include diversifying your investments. Even when one specific type of investment is doing much better than others, by maintaining a balance you reduce portfolio risk. Accounting for risk may require rebalancing the portfolio, which may sometimes lead to selling and buying different investments.
