All About AI demonstrates a retrospective test using archived information available before a market sell-offBacktesting applies a strategy to historical data to estimate how it would have behaved under past market conditions.. The model expects a roughly flat close and identifies potential sources of volatility, but does not predict the size of the decline.
The presenter then asks the model to identify possible causes given the outcome and explores scenarios involving technology stocks and political risks.
