11/7/2023 0 Comments Look at max drawdown or worst yearThe deepest (or maximum) drawdown is the maximum observed loss from a peak to a trough of a portfolio before a new peak is attained. There are some formula which by accident for "nice" values, but they fail if values have decimals.Īny idea which formula would word all the time. Worst 10 Years Return () - Annualized: 6.36-3.45-5.38: Best 10 Years Return () - Annualized: 8.83: 14.53: 14.53: 20.41: Worst 10 Years Return () - Annualized: 4.28-5.88. Obviosley it is the next higher figure which comes after 13 (but in an unsorted array). Question is now what formula to use which as a result gives the index (stock value of 14) Recovery has occured when stock value is equal or higher 13. ![]() The draw down recovered at (Stock value 14). In this example drawdown starts at (Stock Value 13,7). įor understanding the problem we have an unsorted array of lets say shares values The beginning I have already as I mentioned.īut how can I calculate zhe end date ? The end of the draw down is when the value of the return has reached the level before draw down has started. These periods show the time windows in the backtest in which the top 10 drawdowns occurred. This chart provides an overview of the worst drawdown periods in the backtest. In this plot, we visualize the drawdown chart described above. What is interesting now ist the so called "recovery time" which ist the date difference between end of the draw down and the beginning. A good benchmark is to have a maximum drawdown of less than 20. ![]() draw down in a period as well as the corresponding dates when the draw down started and when the "valley" was reached. I would like to hook up on the maximum draw down issue.
