What is Implied Volatility Rank (IVR)?

Implied Volatility Rank (IVR) is a crucial concept for options traders. IVR compares the implied volatility (IV) of a security to its historical IV range. IVR is a dimensionless value, typically represented as a percentage, which makes it easy to compare across different tickers and time frames. It is a valuable tool for options traders, especially when trading credit put spreads.

How is IVR calculated?

There are three steps to calculate IVR:

  1. Calculate the 52-week high and low IV for the underlying security.
  2. Calculate the IV percentile – how the current IV ranks compared to its 52-week range.
  3. Calculate IVR as a percentage: IVR = (Current IV - 52-week IV Low) / (52-week IV High - 52-week IV Low)

What does IVR tell options traders?

IVR provides insights into the market's perception of the underlying security's price movements.

  • Low IVR (below 20-30%): The underlying security is expected to have little price movement, making it a good candidate for selling options, like credit put spreads.
  • Medium IVR (30-60%): The underlying security may have average price movement, signaling less certainty or consensus in its future price.
  • High IVR (above 60-80%): The underlying security is expected to have significant price movement, suggesting that it might be overvalued or undervalued.

Practical Application: IVR in Credit Put Spreads

Credit put spreads are popular options strategies that involve selling a put option at a specific strike price while buying a second put option at a lower strike price. By implementing IVR, traders can make more informed decisions about which securities to trade.

Scenario 1: Low IVR

Assume XYZ stock has an IVR of 25% and is currently trading at $50 per share. A trader might consider implementing a credit put spread with the following parameters:

  • Sell 1 OTM (out-of-the-money) put option with a strike price of $48 for a $1.00 credit.
  • Buy 1 ITM (in-the-money) put option with a strike price of $46 for $0.25 debit.

The maximum profit for this credit put spread is $0.75 ($1.00 - $0.25), realized if XYZ stock closes above $48 at expiration. The maximum loss is limited to the net debit paid, which is $0.25.

Scenario 2: Medium IVR

If XYZ stock's IVR rises to 45%, traders might consider being more cautious with credit put spreads. The underlying security may experience more price volatility, making it harder to predict the price movement.

Scenario 3: High IVR

With XYZ stock's IVR at 65%, the implied volatility suggests greater price movement. Selling a credit put spread in this scenario might be riskier, as the underlying security is more likely to move beyond the trader's expectation.

Considerations and Best Practices

While IVR is a helpful tool, it is crucial to remember that it does not predict the direction of price movement. It only suggests the magnitude of expected price fluctuations.

  • Combine IVR with other technical analysis indicators and fundamental analysis to improve trading decisions.
  • Always set proper risk management rules and position sizing.
  • Regularly monitor the IVR and adjust your trading strategy accordingly.

With the right approach and understanding, IVR can benefit options traders and help them make more informed decisions about implementing credit put spread strategies.
