How to measure the performance of your portfolio
1. Review Your Portfolio's Return
The most common and straightforward way to measure the performance of your portfolio is to look at its return. Your portfolio return is the amount of money it has earned in a given period. This return calculation takes into account all the investments you hold, including stocks, bonds, and other securities.
To calculate your portfolio return, you'll need to subtract the amount you invested from the total current value of your portfolio. Then, divide that number by the amount you invested, and multiply by 100 to get a percentage.
For example, suppose you invested $10,000 in your portfolio, and it's now worth $12,000. Your portfolio return would be (12,000 – 10,000) / 10,000 x 100 = 20%.
2. Risk-Adjusted Returns
While calculating the return on your portfolio is essential, it's not the only factor to consider when evaluating your portfolio's performance. The risk you take on your investments should also be taken into account. That's where risk-adjusted returns come in.
Risk-adjusted returns measure the amount of return you earn per unit of risk taken. By taking on more risk, you may earn a higher return, but you could also suffer significant losses.
For example, suppose you earn a 15% return on your portfolio and a benchmark index gains 10%. However, your portfolio is more volatile than the benchmark, meaning it takes on more risks. In that case, your risk-adjusted return may be lower than the benchmark return.
3. Sharpe Ratio
The Sharpe ratio is a popular method for measuring the risk-adjusted return of a portfolio. It's calculated by subtracting the risk-free rate of return (such as the yield of a Treasury bill) from the portfolio's return and dividing that number by the portfolio's standard deviation. This calculation gives investors an idea of how much return they're earning for each unit of risk taken.
A Sharpe ratio of one or higher is considered good, indicating you're earning a decent return compared to the risks you're taking on.
4. Compare Portfolio to Benchmarks
Another way to measure the performance of your portfolio is to compare it to a benchmark. Benchmarks are standard measurements of investment performance that represent a particular market, sector, or index.
For example, if you have a portfolio of tech stocks, you may compare your returns to the NASDAQ index. Similarly, if you have a diversified portfolio, you may compare your returns to the S&P 500.
By comparing your portfolio's performance to a benchmark, you can determine if your portfolio is outperforming or underperforming. If your portfolio's performance consistently lags the benchmark, it may be time to adjust your investment strategy.
5. Drawdowns
Drawdowns refer to the reduction in your portfolio's value during a specific time period. Measuring drawdowns is crucial because it allows you to manage risk by limiting losses. By analyzing your portfolio's drawdowns, you can determine your maximum tolerable loss, also known as your risk appetite.
To calculate drawdowns, you'll need to look at the peak portfolio value and the lowest point your portfolio reached during a particular period. Divide the difference between the two by the peak value, and you'll get the drawdown percentage.
6. Tracking Error
Tracking error measures the deviation between your portfolio's performance and a benchmark. Tracking error helps you determine how closely your portfolio mirrors the benchmark and whether it's worth taking on the extra risk to achieve higher returns.
If your portfolio consistently underperforms the benchmark due to a high tracking error, you may need to reconsider your investment strategy or choose a different benchmark for comparison.
Final Thoughts
Measuring the performance of your portfolio is crucial for any investor who wants to achieve long-term wealth and financial security. By considering the various measurements outlined in this article, you can track your portfolio's performance and make informed decisions to improve its returns while minimizing risks. Remember that measuring the performance of your portfolio should be an ongoing process, and you should review your performance regularly.
