Update: On September 18th ProShares will reverse split SVXY 4 for 1. If you own SVXY shares you will see the number of shares you’re holding decrease by a factor of 4 and the price will roughly quadruple. Fractional shares will be cashed out. For more information see the ProShares press release. If you are holding SVXY options at the time of the split your options will be adjusted. For reverse splits the process for options is quite ugly, you don’t lose any money—at least theoretically but the number of shares controlled by each contract goes down from 100 to 25. For more on the option adjustment process for reverse splits see this post.
Just about anyone who’s looked at a multi-year chart for a long volatility fund like Barclays’ VXX has thought about taking the other side of the trade. ProShares’ SVXY is an Exchange Traded Fund (ETF) that allows you bet against funds like VXX while avoiding some of the issues associated with a direct short.
To have a good understanding of how SVXY works (full name: ProShares Short VIX Short-Term Futures ETF) you need to know how it trades, how its value is established, what it tracks, and how ProShares makes money with it.
SVXY went through some serious trauma in February 2018. An unprecedented VIX spike and an apparent VIX future liquidity gap in the late afternoon of February 5th, 2018 resulted in a 90% drop in SVXY’s value and the termination of XIV—a similar fund. On February 27th, 2018, Proshares moved to reduce the chances of a similar event in the future by lowering SVXY’s leverage from -1X the daily moves of SPVXSP, the VIX futures index it tracks, to -0.5X. This change reduces the chances of a similar drawdown, or of the fund terminating but also reduces the upside potential of SVXY. This leverage change became effective February 28th, 2018.
How does SVXY trade?
- SVXY trades like a stock. It can be bought, sold, or sold short anytime the market is open, including premarket and after-market time periods. With an average daily volume of 14 million shares, its liquidity is excellent and the bid/ask spreads are a few cents.
- SVXY has options available on it, with five weeks’ worth of Weeklys and strikes in 50 cent increments.
- Unlike Barclays VXX & VXXB, SVXY is not on a hell-ride to zero.
- SVXY can be traded in most IRAs / Roth IRAs, although your broker will likely require you to electronically sign a waiver that documents the various risks with this security. Shorting of any security is not allowed in an IRA.
- SVXY is subject to termination risk. Termination can occur (and did with XIV, a very similar fund on February 5th, 2018) if the daily positive move in the VIX futures market approaches or exceeds 200%. ProShares guarantees that SVXY will not go negative so to protect themselves they will cover their short positions and terminate the fund if things get bad enough. For more on this see XIV Termination.
How is SVXY’s value established?
- Unlike stocks, owning SVXY does not give you a share of a corporation. There are no sales, no quarterly reports, no profit/loss, no PE ratio, and no prospect of ever getting dividends. Forget about doing fundamental style analysis on SVXY. While you’re at it forget about technical style analysis too, the price of SVXY is not driven by its supply and demand—it is a small tail on the medium-sized VIX futures dog, which itself is dominated by SPX options (notional value > $100 billion).
- The value of SVXY is set by the market, but it’s closely tied to the daily percentage moves of the inverse of an index (S&P VIX Short-Term Futurestm) that manages a hypothetical portfolio containing VIX futures contracts with two different expirations. Every day the index methodology specifies a new mix of VIX futures in the portfolio. On a daily basis SVXY moves in the opposite direction of the index with a leverage factor of -0.5X, so for example, if the index (ticker SPVXSPID) moves up 0.3%, then SVXY will move down precisely 0.15%. This post has more information on how the index itself works. The index is maintained by S&P Dow Jones Indices.
- As is the case with all Exchange Traded Funds, SVXY’s theoretical share value is just the dollar value of the securities and cash that it currently holds divided by the number of shares outstanding. This theoretical value is published every 15 seconds as the “intraday indicative” (IV) value. Yahoo Finance publishes this quote using the ^SVXY-IV ticker. The end of day value is published as the Net Asset Value (NAV). The NAV is computed at 4:15 ET, not the usual market close time of 4:00 ET, because VIX Futures don’t settle until 4:15. I recommend that anyone that trades SVXY also keep its IV ticker on your watchlist. If the two prices diverge significantly it indicates that the markets are in turmoil and extra care is mandated. If in doubt trust the IV price.
- If the trading value of SVXY diverges too much from its IV value wholesalers called Authorized Participants (APs) will normally intervene to reduce that difference. If SVXY is trading enough below the index they start buying large blocks of SVXY—which tends to drive the price up, and if it’s trading above they will short SVXY. The APs have an agreement with ProShares that allows them to do these restorative maneuvers at a profit, so they are highly motivated to keep SVXY’s tracking in good shape.
What does SVXY track?
- SVXY makes lemonade out of lemons. The lemon, in this case, is the index S&P VIX Short-Term Futurestm that attempts to track the CBOE’s VIX® index—the market’s de facto volatility indicator. Unfortunately, it’s not possible to directly invest in the VIX, so the next best solution is to invest in VIX futures. This “next best” solution turns out to be truly horrible—with average losses of 5% per month. See this post for charts on how this decay factor has varied over time. For more on the cause of these losses see “The Cost of Contango”.
- This situation sounds like a short sellers dream, but VIX futures occasionally go on a tear, turning the short sellers’ world into something Dante would appreciate.
- Most of the time (75% to 80%) the SVXY strategy is a real moneymaker—the rest of the time it is giving up a lot of value quickly. My simulation shows that 65%+ drawdowns would have occurred if the -0.5X SVXY had been trading in the 2004 to 2017 timeframe. The chart below shows -0.5X SVXY from 2004 using historic VIX Futures values to generate simulated values.
- Understand that SVXY does not implement a true short of its tracking index. Instead, it attempts to track the -0.5X percentage inverse of the index on a daily basis. To maintain this -0.5X behavior the fund must rebalance/reset its investments at the end of each day. For a detailed example of how this rebalancing works see “How do Leveraged and Inverse ETFs Work?”
- There are some very good reasons for this rebalancing, for example, a true short can only deliver at most a 100% gain and the leverage of a true short is variable (for more on this see “Ten Questions About Short Selling”). The simulated -0.5X SVXY, on the other hand, is up over 600% since VIX futures started trading in March of 2004 and it should faithfully deliver a daily percentage move very close to -0.5X of its index.
- Detractors of the daily reset approach correctly note that SVXY and funds like it can suffer from volatility drag. If the index moves around a lot and then ends up in the same place SVXY will lose value, whereas a true short would not, but as I mentioned earlier, true shorts have other problems. Even with volatility drag daily reset funds don’t always underperform. If the underlying index is trending down, they can deliver better than -0.5X cumulative performance.
How does ProShares make money on SVXY?
- An Exchange Trade Fund like SVXY must explicitly hold the appropriate securities or equivalent swaps matching the index it tracks. ProShares does a very nice job of providing visibility into those positions. The “Daily Holdings” tab of their website shows how many VIX futures contracts are being held. Because of the -0.5X nature of the fund, SVXY will typically be short VIX futures contracts with a notional (list price) value half of the overall asset value of the fund.
- ProShares collects a daily investor fee on SVXY’s assets. The fee is stated as a 0.95% annual fee, but it’s implemented by subtracting 0.95/365 of a percent from each share’s value every calendar day. With current assets of around $800 million, this fee brings in around $7.6 million per year. That should be enough to be profitable, however, I suspect the ProShares’ business model includes revenue from more than just the investor fee.
- Exchange Traded Funds like SVXY recoup transaction costs in a non-transparent way. Transaction costs are deducted from the fund’s cash balance—resulting in a slow divergence of the fund’s IV value from the theoretical value of the index that it’s tied to. This differs from the approach that Exchange Traded Notes (ETN) use, their theoretical value is directly tied to the moves of the index itself, so the ETN issuers must pay for transaction costs other ways (e.g., out of the annual investor fee, or other explicit fees). In the case of SVXY, this hidden transaction fee has averaged around 0.28% per year.
- One clue on ProShares’ business model might be contained in this sentence from SVXY’s prospectus:
“A portion of each VIX Fund’s assets may be held in cash and/or U.S. Treasury securities, agency securities, or other high credit quality short-term fixed-income or similar securities (such as shares of money market funds and collateralized repurchase agreements).” Agency securities are things like Fannie Mae bonds. The collateralized repurchase agreements category strikes me as a place where ProShares might be getting significantly better than money market rates. With SVXY currently able to invest around $250 million this could be a significant income stream.
- I’m sure one aspect of SVXY is a headache for ProShares. Its daily reset construction requires its investments to be rebalanced at the end of each day, and the required investments are proportional to the percentage move of the day and the amount of assets held in the fund. SVXY currently holds $800 million in assets, and if SVXY moves down 10% in a day (the record negative daily move is -24%, positive move +18 %) then ProShares must commit an additional $40 million (5% of $800 million) of capital that evening. If SVXY goes down 10% the next day, then another $36 million capital infusion is required.
SVXY won’t be on any worst ETF lists like Barclays’ VXX, but its propensity for dramatic drawdowns (e.g. -48% on 5-Feb-2018!) will keep it out of most people’s portfolios. Not many of us can handle the emotional stress of holding on to a position with huge losses—even though the odds support an eventual rebound.
The eye-popping inverse volatility gains in 2016 and 2017 were followed by a mass destruction drawdown on February 5th, 2018 that hammered the old -1X SVXY and XIV EPTs by -90% or more. This new, lower leverage version of SVXY will be less prone to huge drawdowns/ termination, but bloodletting during volatility spikes will still occur. People will continue to forget how short volatility can be very volatile in its own right.
