GLD Expected Move Calculator
Calculate the expected price range for SPDR Gold Shares (GLD) based on implied volatility and time to expiration.
GLD options reflect gold price dynamics. IV rises during inflation fears, currency crises, and geopolitical uncertainty.
Over the last three months GLD has been on the calmer end for individual stocks: 24.5% annualized realized volatility (under 25% band). Quiet stretches keep expected moves narrow. If the option chain's IV sits well above this, the market is pricing in more movement than the stock has lately delivered — often ahead of a catalyst.

Worked Example: GLD Expected Move at $380.14
Using GLD's last quote of $380.14 (as of October 2, 2026), with GLD's own 3-month realized volatility of 24.5% standing in for IV. Implied volatility usually runs above realized — especially before earnings — so enter the at-the-money IV from your option chain for the market's number.
30-day 1σ move (~68%)
±$26.70 (±7.0%)
$353.44 – $406.84
30-day 2σ range (~95%)
±$53.40
$326.74 – $433.54
7-day 1σ move
±$12.90
$367.24 – $393.04
$380.14 × 24.5% × √(30 / 365) = $26.70
- GLD sits 18% of the way from its 52-week low ($351.40) to its high ($509.70). The 30-day 1σ band spans 34% of the width of that 52-week range.
- At this volatility, the 2σ band reaches below the 52-week low of $351.40 — a tail move would put GLD somewhere it hasn't traded all year.

Trading GLD Options & Expected Move
GLD's expected move expands during inflation prints, real-yield shifts, and currency-crisis episodes, with central bank purchase activity adding a slower-moving structural driver. Options chains are liquid in monthlies and decent in weeklies, though far-out-of-the-money strikes can be thin. Traders use GLD as a portfolio hedge and often pair it against TLT or DXY to isolate real-rate versus nominal-rate effects. Skew is generally balanced but can tilt to calls during risk-off episodes when gold rallies sharply. Beyond CPI prints, FOMC meetings, and major geopolitical events are recurring catalysts. When pricing expected move, factor in any upcoming central-bank meeting calendars, as policy surprises have historically produced multi-day drifts that exceed the prior week's implied daily range.
Expected Move Formula
Expected Move = Price × IV × √(DTE / 365)
1σ Range: Price ± Expected Move (≈68% probability)
2σ Range: Price ± 2 × Expected Move (≈95% probability)

- What does GLD's implied volatility tell me?
