By revenue butterflies, we check with 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 destructive 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 (virtually at pre-Covid ranges), many merchants ask if they’ll commerce butterflies at such low volatility.

Volatility is mean-reverting. With volatility at its low level, it should doubtless return up in some unspecified time in the future.
When?
Nobody is aware of.
How can we shield our butterfly if volatility goes up?
Give it some destructive delta.
To ensure that volatility to go up, the market most probably would have dropped.
Having some destructive delta to revenue from this down transfer will compensate for our loss on account of destructive 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 destructive -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)?
Not likely.
Let’s see how we are able to get higher pricing and reward-to-risk when we now have the next IV, corresponding to on March 13, 2023, when the VIX is 25.
This butterfly can also be a 60/70 butterfly.
It has an identical 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’t 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 an alternative 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 at the least bettering within the right path.
Butterflies are merely much less environment friendly at getting cash in a low IV surroundings.
It will not be 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 intervals.
And others could begin pairing the technique with different methods which carry out higher in decrease IV environments (corresponding to calendars).
However that’s as much as you.
In case you should commerce butterflies throughout low IV, give it some destructive delta to guard it if IV spikes.
And prolong the DTE to longer phrases to decrease its price and enhance its reward-to-risk ratio.
