This is a really interesting approach. What stands out to me is that you’re essentially trying to move from broad factor exposure to more precise “behavioral matching” between assets.
In practice, it makes sense that clustering can reduce hedging error because you’re identifying securities that actually move together in real conditions, not just through predefined factors. Industry classifications and even factor models can miss that nuance, especially in periods where correlations shift.
The tradeoff I think becomes important is stability vs. precision. Highly correlated pairs or clusters can reduce error in the short term, but those relationships can break down quickly during regime shifts, especially in more volatile environments or when macro drivers change.
It would be interesting to see how this holds up across different market regimes; for example, high volatility vs. low volatility environments, or during periods of strong sector dispersion versus broad market moves.
Really good work, feels like a step toward more adaptive hedging rather than static factor-based approaches.
I wonder how the effectiveness of clustering-based hedging might vary across different market cycles or economic conditions, and whether there are specific industries where this approach is more or less reliable.

Clustering tends to capture factor exposures much better than simple sector hedges.
Great work!
thanks bruh
hey I want to be a quant when I graduate, your posts look very interesting, great content!
