What is this Table?

The ASX IV Reference table is built to quickly analyse the top optionable stocks on the ASX by comparing Implied Volatility data.

Reference Vol (Reference Implied Volatility)

In house analysed and tested metric to determine the stocks normal Implied Volatility. We know each stock has a normal Implied Volatility, due to how much market perceived risk there is; growth stocks have more IV than Blue-Chip names.

We've created our reference volatility by analysing this historical Implied Volatility, Historical Realised Volatility and long-term derivatives prices to determine a value. Always subject to change.

Current Vol (Current Implied Volatility)

The current Implied Volatility number from at-the-money 30 DTE Options, derived from current options prices on the market.

Ratio

The Ratio between Reference Implied Volatility and Current Implied Volatility. A number below 100% means that current IV is cheap compared to the reference IV, whereas a number above 100% means that current IV is expensive compared to the reference IV. This may act as a signal in determining either buying options premium or selling options premium.

30D EM +- (30 Day Expected Move + / - %)

The expected range of the assets movement over the next 30 Days, determined by the current IV. Is closely linked to and often resembles the 1 Standard Deviation move of the underlying stock or 68% chance of success settling within the range.

IV Rank (Implied Volatility Rank)

The IV Rank (or IVR) is a measurement of an assets current Implied Volatility in reference to its Historical Implied Volatility over the last 52 weeks. It's a number between 0 and 100, 0 meaning that IV hasn't been lower in the last 52 weeks, and 100 stating that IV has never been higher for that asset.

Formula: (Current IV - 1-year low IV) / (1-year high IV - 1-year low IV)
