By earnings butterflies, we seek advice from non-directional flies that depend on theta decay for his or her revenue.
These methods profit when implied volatility (IV) drops as a result of they’re detrimental vega trades.
However with IV so low already, how far more can it go?
The VIX is the CBOE Volatility Index and is a well-liked measure of the implied volatility of the S&P 500.
As of June 2023, the VIX is at a low of 14.
With the VIX on the lowest level in 3 years (nearly at pre-Covid ranges), many merchants ask if they will commerce butterflies at such low volatility.
Volatility is mean-reverting. With volatility at its low level, it would possible return up in some unspecified time in the future.
Nobody is aware of.
How can we defend our butterfly if volatility goes up?
Give it some detrimental delta.
To ensure that volatility to go up, the market most certainly would have dropped.
Having some detrimental delta to revenue from this down transfer will compensate for our loss on account of detrimental vega.
Contemplate the next butterfly on June 30, 2023, the place the VIX was at a three-year low of 13.
It has 35 days until expiration (DTE) and has a detrimental -0.8 delta.
It prices $780 for one contract on the SPX.
The expiration graph determines the reward-to-risk, which is about 3, calculated by $5200/$1750.
Is that this good pricing? Is that this a very good reward-to-risk for this 60/70 butterfly (60 factors higher wing and 70 factors decrease wing)?
Let’s see how we will get higher pricing and reward-to-risk when we have now the next IV, akin to on March 13, 2023, when the VIX is 25.
This butterfly can also be a 60/70 butterfly.
It has the same 32 DTE.
Nevertheless it solely prices $70 for one contract.
Its reward-to-risk is about 6 (twice as a lot because the June butterfly).
That is the benefit of placing on these butterflies at excessive IV.
However we can not all the time have excessive IV. How can we commerce these butterflies at decrease IVs?
Let’s strive extending the DTE to 77 for the June butterfly.
Now the 60/70 butterfly with the identical strikes prices $355 as a substitute of $780 (half as a lot).
The reward-to-risk has improved barely to $5500/$1500 = 3.6.
Whereas that is nonetheless inferior to the butterfly in excessive IV, the metrics are no less than enhancing within the right route.
Butterflies are merely much less environment friendly at making a living in a low IV surroundings.
It is probably not apparent why that is the case, however modeling the butterflies in OptionNet Explorer throughout excessive and low IV environments simply seems that is the way in which it’s.
Some skilled butterfly merchants will scale down their butterflies throughout these decrease IV durations.
And others might begin pairing the technique with different methods which carry out higher in decrease IV environments (akin to calendars).
However that’s as much as you.
In case you should commerce butterflies throughout low IV, give it some detrimental delta to guard it if IV spikes.
And lengthen the DTE to longer phrases to decrease its price and enhance its reward-to-risk ratio.
