Discussion
Introduced by Barclays in 2009 and redeemed in 2019, VXX was a 10-year ETN, or Exchange Traded Note, that tracked the VIX Short-Term futures. As VXX was approaching the redemption date Barclays introduced a new 30-year iteration of the same product called VXXB on Jan 17 2018. On May 2 2019, Barclays renamed VXXB to VXX.
The 50D option strategies outperformed buy/hold SPY from a total return perspective. However, they had a wild ride along the way as demonstrated by the sharpe ratios.
Nevertheless, the swings of the short call option strategies pale in comparison to a “buy/hold” short position in VXX. Let’s see what that would look like.
Using iBorrowDesk (search VXXB – they haven’t updated the ticker yet), we see that from Sept 17, 2018 till Sept 12, 2019 Interactive Brokers charged anywhere between 1.4% and 6.7% to borrow this underlying. The majority of the time the borrow cost has hovered between 3.0% and 3.2%.
Let’s call it 4% and factor that into the equity curve. We end up with the following chart.
Not too shabby if you’re okay with multiple million-dollar swings.

Great test. Looks like commissions really eat into the 5 delta. For people trading on a commission free broker that may swing the sharpe ratio more in their favor over SPY. Also seems like this would be a good one for a short call spread to help with some of those cases where VXX shoots up really quickly.

Interesting, is this the first backtest that actually beats SPY?
Remind me (I couldn’t find it in the methodology) – what do “50D-50”, “30D-50”, etc mean? Is that a 5D spread?
September 13, 2019 @ 12:54 pm
It is, but not on a risk-adjusted basis. EEM was the first I observed that had both a risk-adjusted and total return outperformance relative to the underlying.
50D-50 is a 50D position managed at 50% max profit or 21 DTE. 30D-50 is a 30D position managed at 50% max profit or 21 DTE. Not to be confused with 50D-30D-50, which is a 50D 30D spread (the study name will indicate whether it’s a credit or debit) managed at 50% max profit or 21 DTE.
I’ll update the methodology section to include clarity on the naming convention. Appreciate the feedback.

VXX short call spread is coming next week – stay tuned 🙂
September 14, 2019 @ 3:10 am
I wouldn’t go on with a short call – it’s the way optionsellers.com ruined their depot…
There is also a danger with the VXX for a Explosion.
So i’m looking forward for the short call spread

Thanks for the back-testing.
1)How much was the max. loss during the trade? you wrote that
“the worst monthly return for example for 30D was -44.6%”
2) that means that if I sold a 30D call on VXX for $100 the max. loss was -$144.60?
3) During the month the 30D call for example didn’t show bigger loses?
4) I didn’t find the “VXX short call spread ” back-testing, can you please write the link?
October 20, 2019 @ 7:03 am
You’re welcome; thanks for stopping by!
1) ORATS reports that the max drawdown on the cash-secured VXX 30D hold-till-expiration strategy is 47.48%.
2) That means if you had $100 committed to the 30D strategy (think of it as investing $100 in an ETF that implements the 30D strategy behind the scenes) during the worst month, the $100 would become $55.4 – a loss of 44.6%.
3) That’s a good question. The cash-secured stats provided by ORATS reports as a monthly rollup. It’s quite possible a greater loss occurred during the “worst month”, or even a different month, but some winners may have occurred that brought the returns up from the lowest of lows. If we evaluate this as a leveraged strategy using the Options Backtest Builder – I’ve yet to do this on this particular study – we’ll see the exact day in which the bottom of the max draw down occurs.

What do you mean with ” cash secured call”?
for example if VXX is trading at $13
this study sell 10 calls $13 in a $13,000 account?
January 29, 2020 @ 3:49 pm
Essentially, yes.
January 29, 2020 @ 3:55 pm
Thanks! And during this study never received a margin call (or the balance went negative)?
January 29, 2020 @ 4:45 pm
Welcome!
I can’t speak to whether this would have generated a margin call in practice. That’s unfortunately something that can’t be explored with a backtest (particularly, buying power expansion). Notably, the account didn’t blow up despite the multi million dollar sings.
