Abstract
We examine the hedging challenge where futures positions can be automatically liquidated by exchanges without prior notice. Our study presents a semi-closed form solution for an optimal hedging strategy that simultaneously minimizes portfolio variance and reduces liquidation risks due to insufficient collateral. Key findings:
- The optimal strategy depends on extreme return dynamics of spot/futures markets and trader-specific parameters (loss aversion, leverage, collateral management).
- Empirical analysis of Bitcoin demonstrates superior hedge effectiveness with reduced liquidation probability.
- Performance comparison of 7 major direct/inverse hedging instruments across 5 exchanges using minute-level data.
- Novel speculative trading metrics reveal significant venue-based disparities.
