Currency-Hedged Share Classes

When a U.S. investor buys a fund holding European stocks, their return depends on two separate things: how those stocks perform in euros, and how the euro moves against the dollar. A currency-hedged share class is a version of the same underlying fund that uses forward contracts or currency swaps to cancel out that second piece, so the investor's return tracks the stocks' local-currency performance almost exactly, regardless of what the dollar does against the euro.

Fund providers often offer both an unhedged and a hedged share class of the identical underlying portfolio, letting investors choose their currency exposure separately from their choice of what to invest in. An investor who believes European equities will do well but has no particular view on the euro (or actively expects it to weaken) would pick the hedged class to isolate the equity bet; an investor who wants euro exposure as a diversifier would choose unhedged.

The hedge isn't free: it costs the interest rate differential between the two currencies (roughly, the cost of rolling forward contracts) plus a small operational fee, and if the fund is hedging a large notional against a small underlying position, the forward positions themselves can occasionally introduce tracking noise. Hedged share classes are most useful for holding foreign bonds, where currency swings can be larger than the bond's own yield and would otherwise swamp the signal an investor is actually trying to capture.
