ROI is a way to measure an investment's performance. As you'd expect, it's also a great way to compare the profitability of different investments. Naturally, an investment with a higher ROI is better than an investment with a lower (or negative) ROI. Curious how to measure this for your own portfolio? Let's read on.
Whether you're day trading, swing trading, or a long-term investor, you should always measure your performance. Otherwise, how would you know if you're doing well? One of the great benefits of trading is that you can rigorously measure how you're doing with objective metrics. This can greatly help eliminate emotional and cognitive biases.
So, how is this useful? Well, the human mind tends to build narratives around everything as it tries to make sense of the world. However, you can't "hide" from numbers. If you're producing negative returns, something should be changed in your strategy. Similarly, if you feel like you're doing well but the numbers aren't reflecting that, you're probably a victim of your biases.
We've discussed risk management, position sizing, and setting a stop-loss. But how do you measure the performance of your investments? And how can you compare the performance of multiple investments? This is where the ROI calculation comes in handy. In this article, we'll discuss how to calculate return on investment (ROI).
What is return on investment (ROI)?
Return on investment (ROI) is a way to measure an investment's performance. It also can be used to compare different investments.
There are multiple ways to calculate returns, and we'll cover some of them in the next chapter. For now, though, it's enough to understand that ROI measures the gains or losses compared to the initial investment. In other words, it's an approximation of an investment's profitability. Compared to the original investment, a positive ROI means profits, and a negative ROI means losses.
