Inverse volatility—the winner for Short Term is SVXY


Updated: May 25th, 2018 | Vance Harwood | @6_Figure_Invest

http://www.bigleaguekickball.com/category/press/ cheap soma online consultation I used to share stock tips with my brother-in-laws. Before the tech crash I could offer up a few stocks I liked, and they would often make some money.  The crash painfully ended the easy money and I moved onto index funds. They didn’t think indexes were near as much fun.

Doctor shopping for Soma prescription One Easter one of my brother-in-laws asked what I was investing in.   My response was “inverse volatility.” I might as well have said pixie dust.  I stood there wondering where (or if) to start.   First you have stocks, then you have the S&P 500, then you options on the S&P 500, then you have implied volatility calculations, then you have futures on volatility, then you have ETNs with rolling mixtures of futures on volatility (VXX), and then you have the inverse (or the short) of that.   We looked each other in the eye and wordlessly agreed that we wouldn’t start.

I like inverse VXX/VXZ investing.  It’s seldom boring and over the long run the advantage is on your side. Volatility has a return to mean behavior, and volatility futures are almost always in contango—which erodes the value of VXX. If you buy inverse volatility when the VIX is relatively high, your chances of making a good profit eventually are very good.

There are three viable choices in inverse volatility ETN/ETFs.  ProShares offers SVXY an ETF (-0.5X inverse of VXX), and ZIV (daily percentage inverse of medium-term VXZ)—both ETNs, ProShares offers SVXY—same as XIV except it is an ETF, and REX ETF’s offers VMIN.

Barclays offers the XXV and IVOP ETNs which emulate short positions in VXX, but they are essentially dead funds, with very low leverage and volume.   I don’t recommend them.  For the reasons why see this post.

In rating the Barclays, VelocityShare, and ProShares funds I think there are  four primary factors:

  • Liquidity (small bid-asked spreads, getting good fills on orders)
  • Leverage
  • Risk
  • Tax treatment

ZIV’s daily volume is generally  around 50,000 , and its spread runs in the 7 to 10 cent range—not great, but it can handle good size trades (thousands of shares), without getting jerked around.   At times ZIV has been my primary trading vehicle for inverse volatility.  Lots of zip, with lower drawdown risk than the short term products.   For more on ZIV see Trading Inverse Volatility with a Simple Ratio.

On leverage  SVXY is simple, their goal is -0.5X of VXX’s daily percentage moves. The leverage of XXV and IVOP is not so simple.

It turns out that the daily percentage leverage of a short position is a variable which changes as the equity changes in price. For example, if you short XYZ stock at $100, the first $1 move either way delivers 1X leverage—you gain or lose $1, which is +-1/100 = +- 1%. But the further you get from that initiating price, the more the daily leverage changes

For example, imagine after you sell XYZ short at $100 it drops like a rock to $2/share. If it drops the next day from $2 to $1.5, it’s a 25% daily move—but the value of your short position only changes from $98  to $98.5 per share. That’s a 0.5% move and the leverage, 0.5%/25% is only  0.02X. Conversely, if XYZ moves to $150 after you short it at $100, a $1 daily move down (0.67%) changes your position value from $50/share to $51/share—a 2% move which is  2%/.67% = 3X leverage. The graph below shows this relationship.

The drop off to zero leverage on IVOP and XXV  is Barclays’  “Automatic Termination Event” that stops out their inverse funds if they drop  below $10 per share. This prevents these funds from going negative. This termination is a real risk for the Barclay products, IVO was terminated in September 2011 when VXX went above $49.5 per share.

Barclays ETNs only have 1X leverage when VXX is at their inception price.  I think this is a terrible aspect of Barclays’ funds.  When things are going in your favor (volatility dropping) your leverage is dropping, and it climbs rapidly when volatility is spiking—the opposite of what you would like.  This loss of leverage as VXX declines forced Barclays to introduce IVO, because XXV leverage had dropped so low.  In the future as contango grinds away at the VXX value Barclays would need to introduce a follow-on to IVOP to get their leverage back up near the 1X range—but it looks like they are not going to do that. XIV is a clear winner on leverage.

Regarding risk, these are volatile products. They will get hammered when volatility spikes up. In the August/September 2011 correction XIV dropped from 19 to 6.5, a 66% drop in a few weeks. If the market goes into a major bear mode it might take a long time to recover your losses. Recent history has shown that daily percentage funds like XIV weather volatility spikes better than true shorts like IVOP, or the departed IVO.  XIV is a clear winner on termination risk—it is much less likely to automatically stop out investors.  See this post for more information on termination.

Although all inverse volatility funds benefit from the normal contango term structure of volatility futures,  they aren’t reasonable buy and hold choices for investors.  Investors should hedge, or go to the sidelines if the market looks “toppy”.   All your gains can evaporate in a big hurry if the market corrects or crashes.

Will Barclays respond to XIV’s growing success by introducing a 1X leverage fund? I doubt it. They have a great situation with XXV and IVOP—every dollar invested in these funds is a perfect hedge against their other short term volatility product: VXX.   They can skip the hedging expenses on both sides because they hedge each other, and Barclay can collect their 0.89% annual fee, risk-free.
