On Measuring Volatility
Consider that the concept of volatility can be applied not just to price, but to volume, options prices, market breadth data, etc. Volatility is a characteristic of every slice of the almost infinite flow of data that is associated with the markets.
It’s not just what you measure, it’s how you measure it. Volatility can look forward when it is in the form of a forecast or a derivation, such as implied volatility. When volatility looks backward, the opportunities to get creative are even richer. There is historical volatility, average true range, Bollinger bands, Chaikin volatility, relative volatility, and a variety of ways in which to index volatility.
- Is volatility worth following?
- How can more knowledge about volatility make me a better investor?
- Which aspects of volatility should I pay attention to?
- How should I measure that type of volatility?
- How do I interpret those measurements for maximum ROI?

Getting Tougher to Push Financials Lower from Here?
Halfway through today’s session, my screen is once again filled with red, as the indices look as if they are poised to take a run at yesterday’s lows.
From a sector perspective, the picture is considerably muddier, as two recent laggards, financials (XLF) and consumer discretionary (XLY), are clinging to positive territory as I type this. As I see it, one or the other of these sectors will have to continue to deteriorate if the markets are going to continue lower from current levels.
Given that the financials are already down 53% from their May 2007 highs (see chart below), it is important to keep in mind that the easy money has already been made on the short side. A wide variety of financial sub-sectors (mortgage companies, bond insurers, money center banks, regional banks, investment banks/brokers, etc.) have already made multiple trips to the woodshed – and while some individual issues may still be quite vulnerable going forward, there is a limit to the amount of blood that can be squeezed from a broad-based ETF or index.
Going forward, I suspect the risk/return profile of the financial sector may actually favor the bulls. If the next couple of broad market moves down fail to pull the financials with them, the path of least resistance for the likes of XLF may indeed be up. Keep an eye on this development, because if (and admittedly this is a very large “if”) the financials are done falling, then the markets are likely to be ready to put in a bottom too.

Portfolio A1 Performance Update: 6/30/08
Per reader request, what follows is a snapshot of Portfolio A1 for the month ended June 2008.
The chart below shows the equity curve and some summary performance statistics for Portfolio A1 since the equities only (no ETFs or options), long only portfolio was created on February 16, 2007. During the 16 ½ months since inception, Portfolio A1 has posted a cumulative return (exclusive of dividends) of 23.9%, while the benchmark S&P 500 index has declined 12.1%. This adds up to a net performance of +36.0% for the portfolio vs. the benchmark.
The graphic to the right provides some additional performance details for Portfolio A1 vs. the S&P 500 index over a variety of time frames. For the second quarter of 2008, for instance, Portfolio A1 returned 17.6%, while the S&P 500 was down 3.2%
For the record, Portfolio A1’s current holdings include: Mosaic (MOS); TBS International (TBSI); PetroQuest (PQ); DreamWorks Animation (DWA); and Homex Development Corp (HXM). Portfolio A1 also shares some common ancestry and has a stock ranking system that is similar to the VIX and More Focus Aggressive Trader model portfolio – one of the four model portfolios that I update transaction by transaction for the VIX and More subscriber newsletter.
Finally, I would be remiss in not reiterating that Portfolio A1 was created with tools developed by Portfolio123.com and is managed via Portfolio123.com’s tool set. For more information on Portfolio123.com, please refer to an earlier post on the subject, Portfolio123.com: The Engine Behind Portfolio A1.

NDX Drops 4% and IBD Bag Indicator Is Yellow…
Earlier this month I talked a little bit about the mean reverting bounce associated with a 3% one day drop in the SPX in VIX Spikes and SPX Drops Are Not Necessarily Two Sides of the Same Coin.
Yesterday, we had a 4% drop in the NASDAQ-100 (NDX) and, not surprisingly, the 33 year historical record of 4% drops in the NDX suggests that a bounce is again likely to follow yesterday’s pain. What I found particularly interesting is that the bounce following a 4% NDX drop has a lifespan of only a month or so before any incremental gains revert back to the historical norm. In fact, the maximum post-bounce advantage peaks at about ten trading days, then slowly starts to erode. Looking at data from all 108 of those 4% drops, average performance begins to drop after the tenth day and is decidedly bearish during the period of 2-6 months after that 4% drop.
Part of the reason for this statistical bull trap is the relatively high number of 4% drops in the NDX that occurred during the 2000-2003 period (accounting for 75% of all 4% drops during the 33 year period under study), which lends a bearish cast to the data.
So what about the IBD bag? Well…someone decided to start me on a trial subscription to Investor’s Business Daily about a week or two ago. I scanned the paper for the first few days and noted with a smile that it came wrapped in a green plastic bag. Yesterday the paper arrived in a yellow bag and I wondered if this was some sort of signal from Bill O’Neil or God or perhaps both. Of course, the markets proceeded to plummet on that yellow bag day. So today I look outside in eager anticipation to see what color the bag is and it’s yellow again. This time the markets are only down about 0.7%, but the day is young. I wonder what it means when the paper arrives in a red bag?

New 2008 Low in the DJIA, Yet VIX Shows Complacency
I have received a number of questions and comments in which readers have expressed surprise about the relative complacency in the VIX (currently at 23.51 as I type this) while the DJIA is in the process of making a new low for the year.
One important and often overlooked element of a VIX spike is surprise. Similar to Nassim Taleb’s idea that a black swan cannot be anticipated, if all of the Bob Janjuah’s of the world predict an impending market crash, the media runs with the story, and investors rush out to snap up portfolio protection…then it becomes much less likely that people will panic and the market will crash if stocks start to turn down. Put another way, where there is a safety net, there is a lot less fear.
Another point worth noting is that the DJIA is not representative of the broader markets, as reiterated by Adam at Daily Options Report today in Lookout Below? The Russell 2000 and NASDAQ-100 indices, for instance, are showing considerably more resiliency in the recent downtrend.
Turning to the VIX:SDS ratio, which I unveiled last August in Fear vs. Volatility (follow the links for some background and explanatory notes), I use this indicator to evaluate the amount of fear and complacency in the market relative to market movements. The size and direction of the gap between the current ratio and the 100 day SMA or the 10 day SMA and the 100 day SMA provide some useful information about the incremental sentiment involved in market moves.
At the moment, it looks as if the VIX:SDS ratio is showing a small amount of complacency, which I find a little unusual for the current market environment, but not particularly noteworthy. Of course, if investors see the monster approaching and prepare themselves accordingly, it is a good bet that the monster will never quite make it close enough to terrify the markets.

The Three-Legged Stool
The issue of whether to rely primarily on fundamental or technical analysis is one that each investor has to struggle with, usually a number of times over the course of his or her investing lifetime.
While the relative merits of the two approaches will appeal to different types of investors, I find it hard to believe that the high court of investment strategy will ever rule in favor of one approach at the expense of the other.
None of this stopped Felix Salmon of Portfolio.com from launching an attack on technical analysis in Monday’s Adventures in Technical Analysis, Jim Cramer Edition. After giving Cramer a well-deserved lambasting, Salmon makes the jump from the particular to the general case:
“…Stock traders don't know anything.
It's not just Cramer, is the point. They all do it: even much smarter and much more analytical traders like Barry Ritholtz do it too. Do what? Resort to ‘technical analysis’, which is the art of drawing lines on charts and extrapolating from them what the market is going to do next.
Whenever you hear words like ‘overbought’ or ‘oversold’ or ‘momentum’ or ‘support’ or ‘resistance’, it means that whatever you're hearing is garbage. But it also means that the person you're listening to has no idea what's about to happen, and is therefore resorting to the financial equivalent of astrology.”
For starters, I would consider Cramer to be more of a fundamental guy than a technical analyst, but that is not the important point. Interestingly, to my thinking, Barry Ritholtz spends as much time as anyone writing about macroeconomic and fundamental issues, but this apparently escaped Salmon’s notice as well.
Ritholtz’s succinct response, which can be found in its entirety in Let’s Get Technical, includes a reframing of the question and a quick summary of some of the merits of technical analysis:
A better question to ask is "What information do charts and related data provide, and how can this be used by investors and traders?"
I posit that, when used appropriately, charts and data can provide tremendous insight:
- Provides a statistical approach to investing, one that describes the probabilities of various outcomes (versus making predictions)
- Charts show you if we are in a bull or bear market, allowing you to manage risk appropriately;
- Trends can keep you away from the wrong sectors (Housing, Autos, and Finance are obvious examples) or keep you in the right sectors (eg., Energy and Ag)
- Developing good risk/reward analyses;
- Tracking what the institutions are doing;
- Identifying specific stocks that might be appealing;
The bottom line is that TA is merely a tool, albeit one used more skillfully by some than others.
Finally, consider this question: If you could look at one and only one source before buying your next stock or fund, which would you choose: a fundamental analyst's report (with no charts in it), or any chart of your choosing? While I like having access to both, I cannot ever imagine buying something without first looking at the chart …”
There are many examples of investors who have been very successful investing exclusively with a fundamental approach – and I’m sure there are at least as many investors who have prospered mightily using only technical analysis. Part of the reason investors gravitate to one approach or the other is that it fits their personality and provides a certain level of comfort.
To my thinking, the most important determinant of whether to focus on fundamentals or technical analysis is one’s investment time horizon. In a nutshell, the shorter the time horizon, the more important technical analysis becomes. Find me a day trader, for instance, that invests primarily based on fundamental factors. One the flip side, find me a chartist who is looking at monthly charts covering more than a decade who does not think it is important to be educated on some of the relevant fundamentals that are driving the long-term price action.
Personally, I like to think of my trading style as marrying roughly equal parts of technical analysis and analysis of market sentiment (which I consider to be tangential to TA), informed by a broad view of stock and industry fundamentals, in the context of a larger macroeconomic environment and interrelated global markets. Ultimately, it’s a three-legged stool, with TA, market sentiment, and fundamental analysis providing a balanced perspective.
Finally, I have received a number of comments in which readers have expressed surprise that my subscriber newsletter covers a much broader range of topics than is generally touched upon in the blog. The reasons for this are simple. All the talking heads talk about macroeconomics and fundamentals all day long. There are also a number of blogs and other web sites that spend a lot of time analyzing charts and other TA data. I choose to focus on market sentiment on the blog because I don’t believe this subject gets nearly the attention it deserves. Those who understand volatility, put to call ratios, market breadth data, and other related subjects and who can combine that information with a fundamental + technical approach have a much greater chance of success than those who ignore market sentiment.
In the subscriber newsletter, I utilize a holistic approach to the markets and incorporate a broad range of themes, because I believe it is important to see the whole playing field and not to have any investing blind spots. The approach seems to be working, as I have a 98% renewal rate and am in the process of writing a book on the subject, slated to be published by Wiley Trading in the first half of 2009.

SPY Put Volume Study
For those who were underwhelmed by yesterday’s monthly charts of the call volume and put to call ratios for the VIX, I am going to try to whelm you a little more by switching over to weekly charts of SPY (the ETF for the S&P 500 index) puts.
The logic here is that those who may not want to be short the market (or hedge long positions) with the additional leverage of VIX calls may prefer the increased liquidity, dollar strike price increments, and penny pricing benefits of SPY puts.
Looking at the chart below, the SPY put volume correlates nicely with intermediate bottoms in the SPX/SPY. Note the current spike in put volume. It is something to think about, anyway, as you contemplate what the Fed could possibly say that might put a stop to the slide in the equities market.

VIX Put to Call Ratios and Call Option Volume
I have not yet posted much about VIX call options volume on the blog, but the subject of VIX option volume and put to call ratios is an interesting one that I will return to periodically.
First, I should set some context by pointing out that two years ago, it was rare for VIX options volume to hit one million contracts in a single month. Following the record 64% one day spike in the VIX on February 27, 2007, VIX options suddenly surged in popularity, with their monthly volume rising steadily and peaking in August 2007 at 7.15 million. Interestingly, since last August, VIX options volume has been fairly steady month to month and has been averaging about 4 million contracts per month.
Given the general increase in activity in VIX options volume, it should come as no surprise that the call volume has surged with the overall options activity. For this reason I have included two VIX options charts, each with the monthly close in the SPX for reference. The top chart shows two years of the VIX monthly put to call ratio. From a quick visual study, it is difficult to conclude that this data provides much in the way of meaningful clues about future trends in the SPX. The bottom chart is a two year history the VIX monthly call volume (with projected end of month volume for June based on data through 6/20/08) and shows a moderate negative correlation between the VIX put to call ratio and movements in the SPX, particularly during 2007. I mention this because VIX call volume for the month of June is on track to be at its highest level in at least 7 months, with the spike in VIX calls increasing the likelihood of a market bottom in the near term.
Consider this an appetite whetter; I will delve more into VIX options and various interpretations of VIX options data in this space going forward.

Volatility at RKH Regional Banking ETF
I just mentioned RKH, the HOLDRS regional banking ETF, on Wednesday in Regional Banking Woes Worsen, where I also posted a graph of RKH’s six month stock price and 30 day implied volatility.
I am revisiting RKH today with a slightly different chart, also courtesy of the ISE, that compares RKH’s implied volatility and historical volatility over the past six months. In the chart below, notice that the implied volatility in this ETF has been more of an uptrend than the spike from mid-March. Notice also that implied volatility appears to have hit a plateau and is still far below the mid-March peak.
Also of interest, the gap between implied and historical volatility is at a six month high right now, as historical volatility has been trending down over the past three weeks at the same time implied volatility has been trending up.
Finally, note that in those instances where historical volatility has been elevated, it usually preceded a drop in implied volatility; conversely, where historical volatility has been depressed, this has a tendency to precede an uptick in volatility. Volatility extremes often signal turning points. Whether the current high implied volatility and low historical volatility means that the regional banks are finally bottoming remains to be seen, but I have to believe that the probability of a bottom is increasing with each volatile session.
