Abstract

fetched live from OpenAlex

This paper formulates a relaxed risk parity optimization model to control the balance of risk parity violation against the total portfolio performance. Risk parity is criticized as being conservative and it is improved by re-introducing the asset expected returns into the model and permitting the portfolio to violate the risk parity condition. The incorporation of an explicit target return goal into a second-order-cone model of a risk parity optimization is proposed. When the target return is greater than risk parity return a violation to risk parity allocations occurs that is controlled using a computational construct to obtain near risk parity portfolios to retain risk parity like traits. This model is used to demonstrate empirically that higher returns can be achieved without the risk contributions deviating dramatically from the risk parity allocations. This study also reveals that the relaxed risk parity model exhibits advantageous traits of robustness to expected returns.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
