Two Quants and a Financial Planner What You Need to Know About Analyzing Backtests
In this episode of the podcast, we dive into the world of backtesting investment strategies. We discuss the importance of approaching backtests with a healthy dose of skepticism, as it's easy to create a backtest that looks impressive but may not hold up in the real world. We explore various questions to ask when evaluating a backtest, such as whether it accounts for human emotions, has a sound economic reasoning behind it, covers a sufficiently long time period, and includes periods of struggle. We also touch on the potential pitfalls of data mining and the challenges of creating a truly "pure" bet without unintended exposures. Throughout the conversation, we emphasize the need to understand the limitations of backtesting and to use it as a tool for learning rather than a definitive guide to future performance.
We hope you enjoy the discussion.
