Beta-Neutral Hedge Notional Calculator

Beta hedge: hedge notional = spot value × (spot beta − target beta) ÷ hedge-instrument beta; optional face value converts to contracts.

Risk disclaimer

Beta drifts and hedges have tracking error; results assume static betas and promise no perfect neutrality.

Why Beta instead of 1:1?

Assets differ in sensitivity to the market (β): spot β=1 tracks the index, so a higher-beta book needs proportionally more hedge.

A target β of 0 means “neutral”; other targets hedge partway or leave deliberate exposure.

How to use

  1. Enter the spot value and its beta (default 1).
  2. Enter the hedge instrument's beta (futures ≈1) and the target beta (default 0).
  3. Optional: enter a per-contract face value for contract count.
  4. Click Calculate for the required hedge notional and contracts.

Formula

  • Hedge notional = spot value × (spot β − target β) ÷ hedge β
  • Contracts = hedge notional ÷ face value
  • Positive means short the hedge; negative means build it long.

Example

Spot 50,000 with β 1, hedge β 1, target 0 → short notional 50,000; face 100 → 500 contracts.

With spot β 1.5 you need 75,000 notional (750 contracts).

FAQ

Where do betas come from?

Usually regression against an index or the venue's spec; this page does not estimate beta for you.

Can the result be negative?

Yes. When the target β exceeds the spot β the result is negative, meaning you long the hedge instrument instead of shorting it.
