![]() ![]() These are the lowest points in the investment's value after a peak and before a new peak is reached.ģ. Calculate Subsequent Trough Values: The subsequent trough values must be determined after identifying peak values. ![]() These are the highest points in the investment's value before a decline occurs.Ģ. Identify Peak Values: The first step in calculating MDD is to identify the peak values of the investment within the chosen time period. This could range from a few months to several years, depending on the investor's preferences and the nature of the investment.ġ. Time Period Under Consideration: The time period for which the MDD is to be calculated must also be specified. ![]() This data can be obtained from various financial data sources, such as stock exchanges, financial news websites, or commercial data providers. Historical Price or Return Data: To calculate MDD, historical price or return data for the investment in question is needed. Calculation of Maximum Drawdown Data Requirements MDD plays a significant role in investment strategies and portfolio management, as it helps investors understand the historical risk of their investments.īy incorporating MDD into their decision-making process, investors can better assess their risk tolerance and make informed choices about asset allocation and risk management strategies. This information is crucial for investors when evaluating the riskiness of an investment and making asset allocation decisions. MDD is an important risk assessment tool because it captures the worst-case scenario for an investment, providing insight into the potential magnitude of losses during periods of market turmoil. Investors and fund managers commonly use MDD to assess the historical risk of various assets and investment strategies. It measures the percentage loss from the peak value of an investment to its lowest point (trough) before a new peak is attained. Perhaps that will be all you need.Maximum Drawdown (MDD) is a risk metric used in finance to quantify the largest decline in an investment's value over a specified time period. Test the solution provided in the youtube video and see if it really works. Once you can identify the peaks and troughs, getting the maximum drawdown should be straightforward. ![]() If this is what you are trying to do, the hardest part is the peak and trough identification. I did not explore in detail if that is an adequate algorithm to find the peak to trough numbers, but he seemed to think it was.Ģ) Once you can compute your drawdowns (peaks to troughs), then it should be a simple MIN() to find the maximum drawdown. Another return from my internet search was this video He uses a simple "to date" maximum to compute the peaks. This kind of "signal processing" algorithm can get quite involved, but will be a key part of how you perform the calculation. I will agree with alansidman, your post assumes that we are all financial experts who know exactly what maximum drawdown is and how it should be calculated.Ī quick internet search found this page that talks about maximum drawdown: Can we assume that this is the definition and computation procedure you are wanting to use for what you call maximum drawdown?Īssuming the investopedia article represents the calculation you are trying to do, here's how I would expect to proceed (note that, without using a VBA UDF or similar, I would expect this to require several helper columns).ġ) You need some way to locate your peaks and troughs. ![]()
