We look at the performance of peers (competitors). It is more than looking at passive benchmarks.

Currency hedging decisions are simple enough to model in the framework of RT. The ex-post optimal currency hedging choice is only one of two decisions.

"A partial hedging policy – such as 50/50 or 70/30 – means the investor won’t ever experience the major highs of an unhedged portfolio, but won’t be subject to the lowest returns either."

"The 50% hedge benchmark is gaining in popularity around the world as it offers specific benefits. It avoids the potential for large underperformance that is associated with "polar" benchmark, i.e. being fully unhedged when the Canadian dollar is strong or being fully hedged when it is weak. This minimizes the "regret" that comes with holding the wrong benchmark in the wrong conditions."

Hedge ratio = 50% if regret aversion dominates risk aversion.
