If you invest in the stock market, you need to rebalance your portfolio. It’s generally not a good idea to invest and never look at your portfolio again. Rebalancing is when you buy and sell assets to match the asset allocation you originally decided on. If this sounds foreign to you, that’s okay. But if you’re investing in the stock market and you don’t know what rebalancing is, take time to learn more about it so you don’t sabotage your efforts. Rebalancing is important. A book that helped me understand this was I Will Teach You To Be Rich by Ramit Sethi.
