Once you’ve implemented your investment portfolio, don’t forget about it! Over time, the asset mix will drift away from its original allocation, as some will perform and some will not. This is when it’s time for some cleanup and rebalancing of your portfolio to bring it back in line. This means shaving off the profits and, depending on the investments, allocating them to the underperformers so that you are buying them at a cheaper price, and averaging down the cost. Rebalancing once a year is usually recommended, but you and your advisor can decide what’s right for you.
