The effect of the rebalancing horizon on the tradeoff between hedging effectiveness and transaction costs

What is it about?

This paper examines the impact of the rebalancing horizon on the transaction costs per hedging effectiveness (TC/HE ratio) for dynamic hedging of the S&P 500 index with 21 commodity indices. This paper produces new evidence that as the rebalancing horizon lengthens, the TC/HE ratio exhibits a monotonically decreasing relationship with positive convexity. This asymmetric effect suggests that hedgers pay more attention to reductions rather than increases in the rebalancing horizons and hedging strategies at short rather than long rebalancing horizons. Although commodities can be used to hedge equity portfolios, they should be used with caution given their low hedging effectiveness.
