VIX Options in Current Declining Volatility Environment

Kudos to Adam at Daily Options Report for today’s A Quick Trading VIX Primer, which provides a succinct explanation of the basis for VIX options prices – some of which have left casual options traders scratching their heads in recent days.

In Adam’s words:

“The VIX estimates volatility on the SPX itself for the next 30 days.

VIX futures are a bet on where that estimate will be on the day the future expires. In other words, it is a snapshot of what the market expects for volatility 30 days AFTER the future expires. If it is a September future for example, you are guessing how the market prices volatility 30 days forward from September expiration. You are not betting on SPX volatility between now and September; that is a common misconception.”

Two graphics might help to illustrate this point. The first graphic initially appeared on VIX and More one year ago in VIX Futures: The One Picture to Remember and shows what happened to the VIX futures on the day before and the day of the record 64% spike on the VIX on February 27th 2007. The bottom line is that the long-term outlook for volatility did not change appreciably, but the VIX futures moved from contango (upward sloping over time) to backwardation (downward sloping over time). So the future still looked the same, but the VIX was expected to take a different path to arrive at essentially the same place.



The second graphic is a snapshot of the VIX options as of this morning. Note that with the (cash/spot) VIX at 17.24, the bid on the May 17.00 puts (0.15) is almost the same as the bid on the May 22.50 calls (0.10). The reason? Mean reversion is priced into the VIX futures – and the options reflect the consensus opinion that a 5 point VIX spike is just about as likely as a 0.25 point drop in the VIX over the next week (recall that VIX options expire on Wednesdays; this month it is one week from today.)

Revert to What?

If there is one thing that most VIX-watchers can agree upon, it is that the VIX is ultimately a mean reverting animal. If you accept that postulate, then the next set of questions that spring to mind generally concern which mean the VIX reverts to and over what time period mean reversion takes place.

Since much of the discussion of the VIX centers around 10 day moving averages, I thought I would zoom out a bit, pull up a VIX weekly chart, and look at some long-term numbers: the 40 and 200 week simple moving averages.

Logically, one might assume that most of the activity in the VIX would fall neatly in between the 40 and 200 week SMAs. Interestingly enough, that has rarely been the case historically. During the past five years, for instance, the VIX has traded in the range between the 40 and 200 week SMA less than 20% of the time, as the VIX has trended down, then back up.

At current levels, the VIX is near the halfway point between the 40 and 200 week SMA, perhaps partly due to some of the gravitational effect of mean reversion. While current levels of volatility appear to resonate as too low for some, a continuation of the bullish bounce off of the March lows should send the VIX back to the 200 week SMA – or even lower.

In sum, while long-term VIX mean reversion does have some analytical use, it is less reliable than the short-term mean reversion patterns that are more commonly utilized for trading.

Strong Bear Signal from VIX:VXV Ratio

I consider the VIX:VXV ratio to be an indicator in the making. Since the VXV is only six months old it is still too early to give it the robust indicator seal of approval, but that doesn’t mean you shouldn’t pay attention to it.

Looking at the chart below, the only previous time the VIX:VXV ratio gave a bearish signal comparable to the current one was just as the markets were about to move down in dramatic fashion from late December to late January.

At the very least, the bulls should consider some downside protection in the current market environment. I suspect the bears are preparing to pounce very soon…

Subscriber Newsletter Update

I have received a number of questions about the subscriber newsletter and I thought this might be a good time to address them.

First, thanks to all who have subscribed. I have been extremely pleased by the response to date. I appreciate all the support and am particularly encouraged by the fact that so far the renewal rate has been 100%.

In terms of content, the Sunday format has already been standardized. The typical Sunday issue is six pages long and has the following sections:

  • The Week in Review – my thoughts on what constituted the important macroeconomic, fundamental, and technical news for the past week
  • The Week Ahead: What to Look For – includes suggestions on earnings to watch, important government data releases, critical technical support/resistance levels, etc.
  • Market Sentiment Update – a discussion of the readings and related implications from two of my proprietary sentiment indicators, the Options Sentiment Indicator (OSI) and the Aggregate Market Sentiment Indicator (AMSI). In some respects these two indicators are descendants of the VIX Weekly Sentiment Indicator (VWSI)
  • Asset Class Outlook – where I update my outlook over the short-term (1-3 weeks), intermediate-term (1-3 months), and long-term (6-12 months) time frames for ten important asset classes that cover US equities, foreign equities, bonds, currencies, and commodities
  • Current Investment Thesis – my take on what is driving the markets, in which direction, and why
  • VIX and More Focus Model Portfolios – three different model portfolios (Aggressive Trader, Growth, and Foreign Growth) consisting of 5-7 stocks each that have returns of +18.0%, -2.7%, and +2.1% since the March 30, 2008 inception
  • Stock of the Week – a single weekly stock selection that has a cumulative return of +48.5% since the initial March 30th selection

The Wednesday issue is much more like the blog, but with a more detailed analysis and a place where I offer more in terms of conclusions and takeaways. It generally runs 4-6 pages and has three standard sections:

  • Market Commentary – updates my thinking as laid out on Sunday
  • Market Sentiment Update – similar to the Sunday section, but may drill down more on specific issues, such as volatility, put to call data, market breadth, volume, etc.
  • Volatility-Based Sector Rotation Model – one of my current research interests is using volatility to time trades on a variety of ETFs, including sectors, geographies, commodities, and currencies. This is not a model portfolio, per se, but I have been providing commentary on what the model is suggesting in terms of sector rotation strategies, what geographies to be long or short in, as well as plays in commodities and currencies

In addition to the three standard sections, Wednesday usually includes several feature sections where the subject matter varies from week to week. Some of the features from the past three issues include:

  • The VIX:VXV Ratio Continues to Perform Well
  • NYSE Total Volume Suggests Rally May Have Run Out of Steam
  • ‘Stock of the Week’ Averages Up 5% in One Day
  • CBOE Equity Put to Call Ratio Remains Bullish (a shorter, updated version of this post went up on the blog a week later)
  • A Long-Term Look at the VIX and the VXN
  • Yield Curve Déjà Vu and Other Musings (a much shorter version of this post went up on the blog later)
  • Is the Fed Done Cutting Rates?
  • Market Breadth and Sustaining a Rally
  • Highs and Lows in the S&P 500 Index

If anyone has any additional questions or comments about the subscriber newsletter, please feel free to email me at bill.luby@gmail.com or check out the subscriber newsletter blog.

The Return of the Links

There was a time where the most popular feature on the blog was my (mostly) weekly set of links to posts on other blogs that had given me something important to chew on. I never intended for that feature to die – and starting today I will do my best to resurrect it.

So without further ado, here is some of what I have been reading and thinking about in the past few days:

CBOE Equity Put to Call Ratio No Longer Bullish

The CBOE equity put to call ratio, which Stockcharts.com and I refer to as CPCE, has been generating consistently bullish readings since the beginning of 2008. Those bullish readings came to an end about a week or so ago, as the chart below reflects. That does not necessarily mean that options sentiment is turning bearish, only that the ‘free lunch’ portion of the bounce off of the March low is over. Now the likelihood of getting whipsawed – either on the long side or the short side – increases considerably. I suspect that a couple more days like yesterday will push options sentiment back into the bullish contrarian camp, but that remains to be seen. Until the market generates a stronger directional signal, priority should be given to conservative strategies.

VIX Surfing Down the Moving Average Channel

I have seen a number of typing heads out there proclaiming that the VIX is “too low” and therefore the recent rally is about to run out of steam. I have my own reasons (yesterday’s VIX:VXV ratio warning sign, for instance) for thinking that the current move is overextended, but labeling the VIX as “too low” is not one of those reasons.

As best as I can determine, most people who use the VIX to time the market focus on the distance between the current VIX value and 10 day simple moving average, with the expectation that the greater the distance between the two, the more likely that the VIX will snap back in the direction of the SMA. With that in mind, consider the chart below, which shows the VIX in the context of the 10 day SMA and two moving average envelopes that show the 10% (dotted green) and 20% (solid green) distance from the SMA. For the last 6 ½ weeks or so, the VIX has been dropping steadily, but in such a fashion that its movements have largely been constrained to a channel between the 10 day SMA and the -10% moving average envelope. At current levels, the VIX is barely 3% below the very same 10 day SMA, hardly what most would consider to be in the “too low” category.

The Commodities vs. Equities Battle Continues…

If the markets seem a more than little indecisive at the moment, one of the reasons is that ongoing sector rotation has muddied the waters with respect to what is hot and what is not. A lot of the sector rotation churning, on the other hand, is merely asset class trickle down, as investors try to decide at a much higher level whether they want to make a substantial commitment to equities and the possibility of a resumption in the recent bull market – or whether the hard assets of commodities are a more attractive option in light of natural resource shortages and concerns about inflation.

The commodities vs. equities battle has been tilting in the direction of commodities in recent months, but since the March lows the consensus has unraveled. In the chart below, the ratio is of the Rogers International Commodity Total Return Index (RJI) to the SPX. [RJI is an ETF linked to the Rogers International Commodities Index that has a broad weighting, with less emphasis on energy than most commodity indices] The ratio chart shows indecision over the past six weeks, with the symmetrical triangle pattern awaiting resolution. I am not sure which side will win the commodities vs. equities skirmish, but when we can declare a victor in this battle, we should know a great deal about the future of the markets over the next few months.

For a longer term perspective on this subject, see my Equities or Commodities? post of a month ago.

Relative Highs and Lows in the SPX

There are a wide variety of ways to measure market breadth, a number of which I have blogged about in the past in some detail. I have not, however, spent much time discussing new highs versus new lows in the S&P 500 index – and given that this blog spends an inordinate amount of time talking about the VIX, it makes sense that much of the analysis here eventually gets tied back in to the SPX.

Of course there is a chart for this – and in this case I have elected to go back through six months of bearish market movement to make my points. The relative high and low chart is best used for two purposes: to identify oversold levels; and to help flag a change in trend. In the chart below, the 20 day EMA dips below the 20 level in both January and February of 2008 for the first time since October 2002, signaling an oversold condition. The change in trend is harder to spot on this chart, but historically a bullish leg is usually underway once the high low index is back over the 65-70 level. Note that the chart ends with Friday end of day data; this week will bring a better sense of the strength of the current rally.

Limited Upside for Consumer Discretionary Sector?

As Corey at Afraid to Trade pointed out in Some Surprising Trend Day Action, one of the more interesting sub-plots in yesterday’s breakout was the strength in the consumer discretionary sector, which rallied 5.8%.

I am firmly of the opinion that the current stock market rally cannot be sustained unless consumer confidence, consumer purchasing power and consumer activity all rally in concert with the markets.

My concern with the consumer discretionary sector extends to a chart of the sector ETF, XLY. In the weekly chart below, the current level of the XLY (33.55 as I type this) is now back to the 32-34 area bounded by the symmetrical triangle formation of 2005-2006 and is also rapidly approaching the 34.08 50% Fibonacci retracement level. Both of these indicators suggest that the XLY should find considerable resistance in the 34-35 area; if this is the case, the market will have to rely on other sectors to continue the current bull rally.

Time for Biotech to Turn Around?

I have been experimenting with a new volatility-centric sector rotation model that I may start talking about in more detail in this space in the coming weeks.

I mention this because the system generated a buy signal in BBH, the HOLDRS biotechnology ETF. While the system does not require a confirmation signal from today’s trading, BBH is trading up with the broader markets today, albeit with a smaller percentage rise. The chart below shows that biotech actually bottomed in January and has not participated in the rally off of the March lows. Generally a healthy biotech sector is an indication of bullish speculative activity. As such, this is one of my ‘indicator species’ charts to watch.

[Note to readers: I have heretofore avoided any disclosure statements when writing about stocks and ETFs. As my content is currently being picked up by Seeking Alpha and other aggregator sites, I will now make it a practice of disclosing positions in any securities mentioned in my posts. If there is no disclosure, this means I do not have a position in any of the securities I reference, as is the case with BBH today.]

Yield Curve Looks Just Like May 2003

There are several places on the web where you can watch a short time-lapse video that shows the recent history of the yield curve. One of those places is Fidelity’s Historical Yield Curve page.

In reviewing the history of the yield curve on the Fidelity site, I was surprised to see that the current yield curve is almost identical to the yield curve as it stood on May 2003. This may just be a historical coincidence, but May 2003 also represents the beginning of the five year bull market that followed the 2002-2003 bottom. In the graphic below, I have added a blue arrow to mark May 2003, which just happens to be the time that the SPX started making higher highs and confirming that a bullish move was underway.

Recall that the inverted yield curve which began in 2006 and caused considerable consternation among investors, turned out to be an excellent – if somewhat early – predictor of the coming stock market top and subsequent economic malaise. Historically a steep yield curve, such as the one we have at present and saw in May 2003, has generally been a harbinger of better times ahead and is often found at the beginning of economic expansions.

Ten Things Everyone Should Know About the VIX

I have had quite a few requests to present some introductory material on the VIX, so with that in mind I offer up the following in question and answer format:

Q: What is the VIX?
A: In brief, the VIX is the ticker symbol for the volatility index that the Chicago Board Options Exchange (CBOE) uses to calculate the implied volatility of options on the S&P 500 index (SPX) for the next 30 days.

Q: How is the VIX calculated?
A: The CBOE utilizes a wide variety of strike prices for SPX puts and calls to calculate the VIX. In order to arrive at a 30 day implied volatility value, the calculation blends options expiring on two different dates, with the result being an interpolated implied volatility number. For the record, the CBOE does not use the Black-Scholes option pricing model. Details of the VIX calculations are available from the CBOE in their VIX white paper.

Q: Why should I care about the VIX?
A: There are several reasons to pay attention to the VIX. Most investors who monitor the VIX do so because it provides important information about investor sentiment that can be helpful in evaluating potential market turning points. A smaller group of investors use VIX options and VIX futures to hedge their portfolios; and an even smaller bunch use those same options and futures to speculate on the future direction of the market.

Q: What is the history of the VIX?
A: The VIX was originally launched in 1993, with a slightly different calculation than the one that is currently employed. The ‘original VIX’ (which is still tracked under the ticker VXO) differs from the current VIX in two main respects: it is based on the S&P 100 (OEX) instead of the S&P 500; and it targets at the money options instead of the broad range of strikes utilized by the VIX. The current VIX was reformulated on September 22, 2003, at which time the original VIX was assigned the VXO ticker. VIX futures began trading on March 26, 2004 and VIX options followed on February 24, 2006.

Q: Why is the VIX sometimes called the “fear index”?
A: The CBOE has actively encouraged the use of the VIX as a tool for measuring investor fear in their marketing of the VIX and VIX-related products. As the CBOE puts it, “since volatility often signifies financial turmoil, [the] VIX is often referred to as the ‘investor fear gauge’”. The media has been quick to latch onto the headline value of the VIX as a fear indicator and has helped to reinforce the relationship between the VIX and investor fear.

Q: How does the VIX differ from other measures of volatility?
A: The VIX is the most widely known of a number of volatility indices. The CBOE alone recognizes nine volatility indices, the most popular of which are the VIX, the VXO, the VXN (for the NASDAQ-100 index), and the RVX (for the Russell 2000 small cap index). In addition to volatility indices for US equities, there are volatility indices for foreign equities (VDAX, VSTOXX, VSMI, VX1, MVX, VAEX, VBEL, VCAC, etc.) as well as lesser known volatility indices for other asset classes such as currencies.

Q: What are normal, high and low readings for the VIX?
A: This question is more complicated than it sounds, because some people focus on absolute VIX numbers and some people focus on relative VIX numbers. On an absolute basis, looking at a VIX as reformulated in 2003, but using data reverse engineered going back to 1990, the mean is a little bit over 19, the high is just below 50 and the low is just below 10. Just for fun, using the VXO (original VIX formulation), it is possible to calculate that the VXO peaked at about 172 on Black Monday, October 19, 1987.

Q: Can I trade the VIX?
A: At this time it is not possible to trade the cash or spot VIX directly. The only way to take a position on the VIX is through the use of VIX options and futures. It is possible that at some point there will be a VIX ETF or a VIX ETN, but no such products have been announced.

Q: How can the VIX be used as a hedge?
A: The VIX is appropriate as a hedging tool because it has a strong negative correlation to the SPX – and is more than four times more volatile. For this reason, portfolio managers often find that buying of out of the money calls on the VIX to be a relatively inexpensive way to hedge long portfolio positions. Similar hedges can be constructed using VIX futures.

Q: How do investors use the VIX to time the market?
A: This is a subject for a much larger space, but in general, the VIX tends to trend in the very short-term, mean-revert over the short to intermediate term, and move in cycles over a long-term time frame. The devil, of course, is in the details.
