What is Rebalancing?

Rebalancing Investment Portfolio

Quick Answer

Rebalancing is the process of adjusting the proportions of different assets in an investment portfolio to maintain a desired level of risk and return. It ensures that the portfolio aligns with an investor's goals and risk tolerance over time.

Overview

Rebalancing is an important strategy in investing that involves realigning the weightings of a portfolio's assets. Over time, as certain investments perform better or worse than others, the original asset allocation can become unbalanced. For example, if an investor initially allocates 60% to stocks and 40% to bonds, a significant rise in stock prices might lead to a situation where stocks make up 70% of the portfolio and bonds only 30%. To rebalance, the investor would sell some stocks and buy bonds to return to the original 60/40 allocation. This process helps to manage risk because it prevents the portfolio from becoming too heavily weighted in one asset class, which can increase volatility. Regular rebalancing can also enhance returns by ensuring that profits are taken from high-performing assets and reinvested into lower-performing ones, which may have more growth potential. Rebalancing matters because it helps investors stick to their financial goals and risk tolerance. Without rebalancing, an investor might unknowingly take on more risk than they are comfortable with, especially during market fluctuations. By maintaining the intended asset allocation, investors can have a clearer path toward achieving their long-term investment objectives.
