## Direct answer

An **inverse ETF** seeks to deliver the opposite of a benchmark's performance, usually for a single day before fees and tracking differences. A `-1x` inverse ETF aims to rise about `1%` when its benchmark falls `1%` in one day, and fall about `1%` when the benchmark rises `1%` in one day.

The key word is **daily**. Multi-day returns are not simply the benchmark's cumulative return multiplied by `-1`.

## How it works

Inverse ETFs often use swaps, futures, options, and cash instruments rather than directly shorting every index constituent. The fund typically rebalances so the next trading day starts with the target inverse exposure relative to current net asset value.

Daily reset creates path dependence. If the benchmark rises one day and falls the next, the inverse ETF compounds from its changed value, not from the original starting value. Volatility, sequence of returns, leverage level, fees, financing costs, derivatives pricing, and execution all affect realized results.

ETF market price can also differ from net asset value. Under stress, when underlying markets are closed, or when derivatives move sharply, premiums, discounts, and bid-ask spreads can become important.

## Example

Start with a benchmark at `100` and a `-1x` inverse ETF at `100`.

Day 1: benchmark rises `10%` to `110`; inverse ETF falls `10%` to `90`.

Day 2: benchmark falls `9.09%` back to `100`; inverse ETF rises `9.09%` from `90` to about `98.18`.

The benchmark is back to its starting level, but the inverse ETF is down about `1.82%`. The difference comes from daily compounding, not from a simple one-time inverse calculation.

In a steady trend, compounding can work differently. If the benchmark falls `10%` on each of two days, it moves from `100` to `81`, down `19%`. A `-1x` inverse ETF would move from `100` to `110` to `121`, up `21%` before fees and tracking differences.

## Risks

- **Daily objective risk:** longer holding periods can diverge sharply from simple inverse benchmark returns.
- **Volatility risk:** choppy markets can erode returns through path dependence.
- **Leverage risk:** `-2x` and `-3x` products magnify gains, losses, and compounding effects.
- **Derivatives risk:** swaps, futures, options, counterparties, collateral, and financing costs matter.
- **Tracking risk:** actual NAV may differ from the theoretical daily target.
- **Trading risk:** spreads, premiums, discounts, and stale underlying prices can affect execution.
- **Hedge mismatch:** an inverse ETF may not match the beta, holdings, timing, or currency exposure of the position being hedged.

## Common misconceptions

An inverse ETF is not a permanent mirror image of an index fund.

Avoiding a direct short sale does not remove risk. It changes the structure of the risk.

If an index falls `20%` over a month, a `-1x` inverse ETF is not guaranteed to rise `20%` over that month.

A reverse split does not create economic value. It changes the share count and per-share price mechanically.
