ProShares Investment Grade-Interest Rate Hedged (IGHG)

A hedge is a financial position taken to reduce the risk of adverse price movements. IGHG holds investment-grade corporate bonds — debt issued by stable, creditworthy companies — and simultaneously buys protection against the interest-rate risk that would normally cause bond values to plummet if rates rise.

The core problem

Investment-grade bonds from companies like IBM, Coca-Cola, and Toyota are issued with a fixed coupon — they pay a set interest rate regardless of what happens in markets. When the Federal Reserve holds rates low, those bonds are valuable because their fixed coupon yields more than newly issued bonds would. But the moment interest rates rise, newly issued bonds offer higher yields, which makes old bonds less attractive. To compensate, their prices fall. A bond bought at par (100) when rates were 2% might be worth only 90 when rates climb to 4% — a significant loss for anyone who needs to sell before maturity.

This interest-rate risk is the defining tension in bond investing. A long-duration corporate-bond fund could see a sharp drawdown if rates climb, yet sitting in cash or short-term bonds yields very little. IGHG attempts to split the difference: hold corporate bonds and capture their yields, but hedge away the interest-rate risk so that rising rates do not cause portfolio losses.

How the hedge works

ProShares uses derivatives — primarily interest-rate swaps and bond futures — to offset the duration risk. When you own IGHG, the fund is simultaneously short the interest-rate exposure that would normally come with owning corporate bonds. If rates rise and the bond holdings decline in value, the hedge positions gain, offsetting the loss. If rates fall, the hedge positions lose, offsetting the gain. The result is a portfolio where you capture the credit spread (the extra yield corporate bonds offer above Treasuries) with minimal directional exposure to rate moves.

The hedge is not free. The cost of those derivatives is built into the fund’s expense ratio, which is higher than a vanilla corporate-bond fund would charge. You are paying explicitly to have that interest-rate risk removed. Over a period of falling or stable rates, you lose that money with nothing to show for it because the hedge never activates. Over a period of rising rates, the hedge is worth far more than its cost.

Who might use IGHG and when

IGHG is designed for investors who want to harvest corporate-bond yields but are fearful of rising-rate scenarios. It is useful in environments where you expect rates to stay flat or rise, because the protection means you will not be punished for that decision. In a falling-rate environment, the hedge is expensive insurance that never pays out, and you would have been better off in a non-hedged corporate-bond fund.

The fund also works as a tactical tool. A portfolio manager holding a lot of long-duration fixed income might add IGHG as a hedge against an unwanted rate-rise scenario while keeping the cash-generating bond holdings in place. Or a conservative investor might use IGHG to avoid the principal risk of bonds while still capturing some yield above Treasury rates.

Tracking error and the real trade-off

Perfect hedges do not exist. IGHG’s protection against rising rates is imperfect because derivatives do not price exactly like the bonds they hedge — there is tracking error and slippage. Some rate environments will cause the hedge to under-protect, leaving you with losses despite the hedging. Additionally, because the fund is holding both bonds and hedge positions, there can be mismatches in timing and volatility that create noise in the daily returns.

The straightforward alternative is to own a shorter-duration corporate-bond fund or investment-grade aggregate ETF, which offers less interest-rate risk but no active hedging cost. The comparison hinges on what you expect rates to do: if you are truly confident they will rise, IGHG is economical; if you are uncertain, you are paying for insurance you may never need.

How to research the fund

The prospectus details the derivative strategies and the fund’s target duration (which should be near zero or neutral if the hedge is working as intended). Review the holdings list and note the credit-quality breakdown — all names should be rated BBB or above. Compare IGHG’s performance versus unhedged corporate-bond funds during rate-rise periods to see whether the hedge earned its cost. Watch the fund’s realized volatility: a properly hedged fund should have far lower volatility than unhedged alternatives, which is the whole point.
