ADVICE

Offset Hedge Beta With Extra Equity Exposure

  • Neutralize a long‑vol strategy's benign negative beta by adding proportional equity exposure (e.g., if hedge has −0.2 beta, add 20% equity).
  • Run both sleeves together so rebalancing creates timing alpha without new cash.
ANECDOTE

Rebalancing Example From 2020 Demonstrates Timing Alpha

  • One River showed a rebalanced combined portfolio that compounded far more than the sum of sleeves in 2020 (example: static sum 58% vs rebalanced compound ~82%).
  • They illustrated resizing sleeves after convexity accrues then rebalancing through recovery to capture compound upside.
ADVICE

Prefer Time Based Rebalancing Over Thresholds

  • Use time‑based rebalancing rather than threshold triggers to avoid path‑dependent mistakes when scaling hedges.
  • One River rebalances incrementally (e.g., weekly quarters to monthly full rebalance) to maximize path independence and remove timing stress.
