What is Backtesting?
Backtesting is a process used to evaluate the effectiveness of a strategy or a computer model by applying it to historical data. Instead of testing a new idea in the live market where money is at risk, analysts run the model against past events to see how it would have performed. This process reveals whether a strategy is based on sound logic or if it relies on patterns that were merely coincidental. By simulating past outcomes, professionals can identify potential flaws, refine their rules, and gain confidence in a system before they deploy it in the real world. It serves as a vital safety check to ensure that a model is robust enough to handle different types of market conditions.
Why this matters to you
It allows you to stress-test your business decisions against past crises or growth periods. By seeing how a strategy would have fared during historical events, you can avoid repeating past mistakes and better understand the risks involved in your current plans.
