XIV Barbell Strategy

Well that was fun! I have been telling my trading buddy and anyone else that would listen that I fully expected XIV to open at zero one day. Now I did not expect it to happen so soon or the way it did. I trade a strategy that can be long XIV or long VXX or in cash. Because of the very likely possibility of XIV blowing up, I had constructed my portfolio using ideas from the barbell portfolio and this post, Taming High Return and High Risk. I was lucky and not in XIV when it did implode on Feb 6, 2018. Could a buy and hold trader of XIV made money even after the crash using these concepts? I was curious.

Barbell Portfolio

The idea of the barbell portfolio is that you put a small percentage of your assets (say 10%) in a very risky, high return asset like XIV. Then with the other 90%, you have it in something very safe like cash. Then at predetermined periods, you rebalance to be back to 10/90 allocation. These rebalance periods can be monthly, quarterly, semi-annual and yearly. What rebalance period you choose and the when can have a huge impact on your results.

Buy and Hold

What are the results of simply doing buy and hold on XIV since inception? You would have lost 59% of your money. All test results are through 2/8/2018.

I wanted to see the results from 2013 because this is about the time I really wanted to trade XIV. A net loss of 73%.

Another time I wanted to see was since 2016 because I know a trader doing this since about then. A net loss of79%.

Ouch, a loss of 79% of your capital. None of these horrible numbers should be surprising

2011 Various Rebalance Times – 50% Allocation

At the rebalance time, the strategy allocates 50% to cash and 50% to XIV. The first thing I notice is that we end up with a decent CAR even though we lost 96% in XIV at the end. Rebalancing yearly exposes you to bad/good timing. I picked these two dates on purpose to show how big of an effect this has. Your CAR is cut in half depending on when you did it. Not as a big impact as semi-annual but still there.  Personally, I like monthly.

The monthly rebalance has a net profit of 64%. Not bad considering.

 

2016 Various Rebalance Times – 50% Allocation

Would you come out ahead of if you started in 2016?

Surprisingly yes for all of these.

2013 Monthly Rebalance – 10%, 25%, 50%, 75% Allocation

How do different allocation amounts look like?

Interesting to see the spike at the 50% allocation level. The 20% allocation has a a CAR of 7% and not too painful MDD of 27%.

Final Thoughts

For aggressive strategies or those strategies likely to blow up, using this method is a great way to reduce the possibility of losing all your money. If I were trading or “investing” in cryptocurrencies, I would use this concept.

It appears SVXY is now a turn-key daily-rebalanced version of this barbell strategy—not that there’s really any other ETP way to do it higher than 0.5 leverage near-dated volatility nowadays.

Historical XIV data from inception (2010 Nov 30) to demise (2018 Feb 15) takes a theoretical buy and hold investor from an adjusted close of $9.56 (rounded up) down to $6.04—a gruesome outcome.

A primitive simulation with a daily-rebalanced (0.5 gain factor each day) XIV takes the same investor, by contrast, from the same inception price up to $21.86 (rounded down), demonstrating some merit to a barbell strategy. Perhaps we should instead call this a dumbbell, though?

A careful active investor could more safely now contemplate no more than a small allocation to a mechanical system with a moving average (e. g., a 150-day mean would have worked, but with 0 days’ margin of error when the price dropped below the MA before the closing bell on Feb 5) or use more sophisticated volatility signals to be in or out of SVXY (perhaps giving some extra days’ warning to get out).

    Trading these instruments is dangerous. It does not matter what your strategy is. Being in or out of XIV before it imploded was luck.
