What is it about?
We use AI to forecast inflation and stock index moves, then translate those forecasts into portfolio rebalancing steps that can help investors protect purchasing power. A key idea is to split the data at major economic turning points, so the models learn from stable and shock periods in a more realistic way.

Why is it important?
Inflation regimes can shift abruptly, and models trained on “normal times” often miss those breaks. This paper is timely because it combines inflation and equity forecasts with a practical hedging use-case: portfolio reallocation. Uniquely, it uses the Zivot–Andrews test to detect structural breaks and tests how different break-based train/test splits change accuracy, improving decision-ready forecasts.
Perspectives
I like that the study treats forecasting as a means to an end: making better allocation decisions under inflation risk. The structural-break approach is especially compelling—markets do not repeat in neat cycles, and letting the data tell us where regimes change makes the results feel more usable. It also highlights a sober point: inflation is often easier to predict than stock returns, so risk management should lean on what is more forecastable.
