Taking The Hedge Off

Hedges get plenty of attention when they're put on — the sizing, the instrument, the ratio all get worked out carefully. Taking a hedge off gets far less scrutiny, but the decision matters just as much: close it too early and the risk it was covering is back on the book unannounced; leave it on too long after it's stopped being needed and it quietly costs money — premium decay, funding, or simply the wrong-way P&L on a hedge that's no longer offsetting anything real.

Reasons to take a hedge off

• The underlying position is closed or reduced. A hedge sized for a position that no longer exists is now a naked bet in its own right, not a hedge.
• The event it was protecting against has passed. An earnings-print straddle bought for a specific date has no reason to stay on once the print is out and the implied volatility that made it expensive has collapsed.
• The hedge has become ineffective. If the correlation it relied on has broken down, holding it on is paying for protection that no longer protects.
• The cost of carrying it now outweighs the risk it covers. Every hedge has an ongoing cost — premium decay, funding, spread — and if the underlying risk has shrunk, that cost may no longer be justified.

The risk of removing it

Taking a hedge off is itself a trade, with its own timing risk. Unwinding a large options hedge or futures position can move the market if done carelessly, and removing protection right before a position turns out to need it is a painful, visible mistake. The same discipline that went into sizing the hedge on the way in — checking liquidity, checking whether the timing coincides with another known event — should apply on the way out.

Worked example

A desk bought a protective put ahead of a Federal Reserve rate decision. The decision comes and goes without a surprise, and implied volatility on the put collapses from an elevated pre-event level back to its normal baseline the next morning. The put is now expensive relative to what it would cost to buy fresh, uneventful protection — its remaining time value has decayed sharply, and it's covering an event that already happened. The desk sells it the same day rather than letting it decay further, since holding it further only bleeds premium with no offsetting event risk left to protect against.

What this means in practice

A disciplined hedging process defines, in advance where possible, the conditions under which a hedge comes off — a date, an event passing, a correlation threshold, a position closing — rather than leaving it as an open-ended judgment call made under time pressure later. Hedges that are never actively reviewed tend to either get forgotten (quietly costing money) or get left on by default well past their useful life.
