A Tale of Three Vols

I know, you’re thinking this is about the Tennessee Vols.

Nope.

Different vol.

I’m not talking about Tennessee Volunteers, I’m talking about the volatility of the stock market.

Someone asked:

“With the S&P 500 is up 3.43% on Friday, volatility is up, way up. So, why is the VIX down -16%? “

The short answer is the CBOE Volatility Index (VIX) is volatility implied by S&P 500 options prices, so it’s expected future volatility, not actual or realized historical volatility. In fact, the VIX is an estimate of volatility for the next 30 days. Part of the price of S&P 500 options is an estimate of how volatile the S&P 500 will be between now and the option’s expiration date.  This estimate is not directly observed but is implied by how much buyers are willing to pay for options.  If the market has been volatile as it has been recently, option premiums will increase with the volatility expansion. When the stock market is calm and smooth like it was in 2017, options prices will decrease as a volatility contraction. So, the VIX is implied volatility, not historical realized volatility.

Since investors tend to extrapolate the recent past into the future, they usually expect recent calm markets to continue and violent swings to persist. However, we’ve experienced nearly a year of a high volatility regime with the S&P 500 swinging up and down in a range as high as 20%. However, we’ve now seen two high volume up days and the second is considered to be an upward follow-through day. Such a thrust seems to have the options market expecting lower volatility over at least the next month. That’s how I see it. Others may believe its a reaction to the economic news. It is what it is.

What is perplexing to those not familiar with VIX movement is it decreased so dramatically as the price actually gained a lot. Volatility actually expanded, but to the upside, and implied volatility evaporated. That doesn’t sound like a volatility gauge.

Another issue is not all volatile calculations really measure upside and downside vol the same way. Below is the S&P 500 index.

  • The first chart in the next window below the price trend is an average true range (ATR) of the price over the past 14 days.
  • The second chart is the VIX.
  • The chart in the last window is the standard deviation.

A few observations:

  1. The price of the S&P 500 has increased sharply the past two weeks.
  2. The VIX is trending down sharply and so is the standard deviation.
  3. The average true range isn’t trending down. It has stayed about the same.

As the price has spiked up, historical volatility as measured by standard deviation is trending down sharply and so is implied volatility. The only measure actually accounting for this wide range of prices (up in this case) is the average true range.

You may be wondering why?

Standard deviation a statistical model that measures the volatility of a price trend. The calculation assumes that two standard deviations should contain 95% of the price data.

The average true range includes the total “true” range of the price trend by comparing highs, lows, and closes, and compares the price change over different days to account for gaps up and down in price.

As you can see, the average true range of price appears to more accurately reflect the volatility as prices spread out. The standard deviation is recovering from the large deviations as the average true range is reflecting remaining day to day volatility.

What does it matter, anyway?

Volatility measures may be used to create indicators for trading signals. For example, in the chart, I added channels above and below the price trend that are 2 times the standard deviation. These bands are expected to include about 95% of price action.

There are two ways it may be used for tactical trading.

A trend following system may use them to identify a breakout because moves outside the price range are rare. A trend following system expects such strong momentum will continue.

  • When the price breaks out the upside, a trend follower may buy, expecting the momentum of the price will keep trending up.
  • If the price breaks out to the downside, the trend following system may sell (short), expecting the downside momentum to continue.

A countertrend system does just the opposite.

  • If the channel is reached on the upside, the countertrend system will sell, expecting the price will reverse back down within the range.
  • If the price falls to the lower channel, the countertrend system will buy, expecting the price is more likely to trend back up within the range.

I’m just sharing this as an observation to answer a question. We could test these signals to see their results as a system to quantify which one may have a better asymmetric risk/reward. But, for this purpose, we can see how these three volatility indicators are similar or different.

I could have titled this observation “A Tale of 4 Vols” since we can observe the distinctions between “lower volatility” and “higher volatility” by simply looking at the price trend. Over the past two years, we’ve certainly observed a period of low vol change into high vol. I call it a volatility expansion and though, for me, using the VIX and other indicators signaled the possible change, the price trend itself is the final arbiter.

By the way, what about the other vol? The Tennessee Vol? Why do they call Tennessee the “Volunteer State” and the Tennessee Volunteers?

Appalachian Magazine shares the story:

“The proclamation went out from Nashville that the federal government needed 2,600 volunteers to assist in the war with Mexico… Within a week’s time, more than 30,000 Tennesseans responded to the call to arms.  And it was from this overwhelming show of patriotism that the State of Tennessee not only assisted in winning the outright sovereignty of the State of Texas, but also in securing its lasting title as The Volunteer State.”

So, there you have it.

I guess I could have titled this observation “A Tale of Five Vols.” You can probably see how observations can spread out to a wider range and become more volatile. It’s even true for the topic of volatility.

Observations of the stock market downtrend

Observations of the stock market downtrend

In the last observation I shared about the stock market, “The stock market trends up with momentum,” we saw the stock market reverse back up with strong momentum. The S&P 500 stock index had declined about -7% from its high, then reversed back up 3%. I discussed how investor behavior and sentiment drives market prices. Many investor sentiment measures signaled investor fear seemed to be in control, driving down prices. Volatility had spiked and then started to settle back down. Many individual stocks in the S&P 500 had declined enough to signal shorter-term downtrends, but then they reversed up. I closed by saying:

In summary, today was a strong upward momentum day for the stock market and most stocks participated in the uptrend. After sharp declines like we’ve seen this month, the stock market sometimes reverses up like this into an uptrend only to reverse back down to test the low. After the test, we then find out if it breaks down or breaks out.

One day doesn’t make a trend, but for those who are in risk taker mode with stocks, so far, so good.

The part I bolded with italics has turned out to be the situation this time.

Below is a year to date price trend of the S&P 500 stock index. As of today, my observation “the stock market sometimes reverses up like this into an uptrend only to reverse back down to test the low” is what we are seeing now.

stock market trend

I’ve always believed investment management is about probability and possibilities, it’s never a sure thing. The only certainty is uncertainty, so all we can do is stack the odds in our favor. As I said before, “After the test, we then find out if it breaks down or breaks out.” 

The positive news is, investor sentiment measures are reaching levels that often precede short-term trend reversals back up.

The bad news is if the current trend becomes a bigger downtrend these indicators will just stay at extremes as long as they want. We have to actively manage our exposure to loss if we want to avoid large losses, like those -20% or more that are harder to overcome.

Down -10% is one thing, down -20% is another. Any investor should be willing to bear -10% because they will see them many times over the years. Only the most passive buy and hold investors are willing to bear the big losses, which I define as -20% or more.

Nevertheless, I see some good news and bad, so here it is. I’ll share my observations of the weight of the evidence by looking at relatively simple market indicators. I don’t necessarily make my tactical decisions based on this, but it is instead “market analysis” to get an idea of what is going on. Observations like this are intended to view the conditions of the markets.

Fear is the dominant driver. 

The Fear & Greed Index tracks seven indicators of investor sentiment. When I included it a week ago, it was at 15, which is still in the “Extreme Fear” zone. The theory is, the weighting of these seven indicators of investor sentiment signals when fear or greed is driving the market. Clearly, fear is the dominant driver right now.

fear greed index investor sentiment behavioral finance

At this point, we can see investor sentiment by this measure has now reached the low level of its historical range. In this chart, we can see how investor sentiment oscillates between fear and greed over time in cycles much like the stock market cycles up and down.

fear and greed back test over time investor sentiment indicator

I believe investor behavior is both a driver of price trends, but investors also respond to price trends.

  • After prices rise, investors get more optimistic as they extrapolate the recent gains into the future expecting the gains to continue.
  • After prices fall, investors fear losing more money as they extrapolate the recent losses into the future expecting them to get worse.

Investor sentiment and price trends can overreact to the upside and downside and the herd of investors seems to get it wrong when they reach an extreme. We observe when these kinds of indicators reach extremes, these cycles are more likely to reverse. It is never a sure thing, but the probabilities increase the possibility of a reversal. But, since there is always a chance of a trend continuing longer in time and more in magnitude, it is certainly uncertain. Since there is always a chance of a bad outcome, I  have my limits on our exposure to risk with predetermined exits or a hedge.

Speaking of a hedge. 

I started pointing out my observation several weeks ago of a potential volatility expansion. If you want to read about it, most of the past few weeks observations have included comments about the VIX volatility index. Over the past few days, we’ve observed a continuation in the volatility expansion.

Implied volatility has expanded nearly 100% over in the past 30 days.

As a tactical portfolio manager, my first focus is risk management. When I believe I have defined my risk of loss, I become willing to shift from risk manager to risk taker. I share that because I want to point out the potential for hedging with volatility. Rather than a detailed exhaustive rigorous 50-page paper, I’m going to keep it succinct.

My day job isn’t to write or talk about the markets. I’m a professional portfolio manager, so my priority is to make trading and investment decisions as a tactical investment manager. I’m a risk manager and risk taker. If I never take any risk, I wouldn’t have any to manage. The observations I share here are just educational, for those who want to follow along and get an idea of how I see things. I hope you find it helpful or at least interesting. It’s always fun when it starts new conversations.

To keep the concept of hedging short and to the point for my purpose today, I’ll just share a simple chart of the price trend of the stock index and the volatility index over the past 30 days. The stock index has declined -8.3% as the implied volatility index expanded over 95%. You can probably see the potential for a hedge. However, it isn’t so simple, because these are just indexes and we can’t buy or sell the VIX index.

vix volatility as a hedge stock market risk management

The purpose of a hedge is to shift the risk of loss from one thing to another. The surest way to reduce the possibility of loss is to simply sell to reduce exposure in the thing that is the risk. That’s what I do most of the time. For example, when I observed a potential volatility expansion, I reduced my exposure to positions that had the possibility of loss due to increased volatility. Once prices fall and volatility contracts, maybe we increase exposure again to shift back to risk-taking. If we take no risk at all, we would have no potential for a capital gain. So, tactical portfolio management is about increasing and decreasing exposure to the possibility of gain and loss. If we do it well, we create the kind of asymmetric risk/reward I aim for.

So, any hedging we may do is really just shifting from one risk to another, hoping to offset the original risk. Keep in mind, as I see it, a risk is the possibility of loss. I’ll share more on hedging soon. I have some observations about hedging and hedge systems you may find interesting.

Most stocks are participating in the downtrend. Below is an updated chart of the percent of the stocks in the S&P 500 that are above their 50-day moving average. If you want to know more about what it is, read the last observations. The simple observation here is that most stocks are declining.

stock market breadth risk indicator

Much like how we saw investor sentiment cycle and swing up and down, we also see this breadth indicator oscillate from higher risk levels to lower risk levels.

  • After most stocks are already in uptrends, I believe the risk is higher that we’ll see it reverse.
  • After most stocks have already declined into downtrends, it increases the possibility that selling pressure may be getting closer to exhaustion.

The good news is, at some point selling pressure does get exhausted as those who want to sell have sold and prices reach a low enough level to bring in new buying demand.

That’s what stock investors are waiting for now.

These are my observations. I don’t have a crystal ball, nor does anyone. I just predetermine my risk levels in advance and monitor, direct, and control risk through my exits/hedging how much I’m willing to risk, or not. We’ll just have to see how it all unfolds in the days and weeks ahead.

Only time will tell if this is the early stage of a bigger deeper downtrend or just another correction within the primary trend.

I hope you find my observations interesting and informative.

The stock market trends up with momentum

When the stock market indexes swing up or down 1% or more I try to share my observations of the directional trend and changes in volatility. Continuing from my observation yesterday in Observations of the stock market decline and volatility expansion when I shared:

The good news is, we’ve now experienced some volatility expansion, stocks have now pivoted down to the lower end of their cycles, so maybe volatility will contract and stock prices resume their uptrend.

We’ll see.

Well, today we saw.

The U. S. stock market gains were broad across all sectors. Communication Services, Consumer Discretionary, Healthcare, and Technology were the relative momentum leaders.

Continuing with the % of S&P 500 stocks above their 50 day moving average as breadth indicator was another indication of broad upward momentum. 86% more stocks are trading above their shorter-term trend, an expansion from a low level. For those of us who like to enter trends early in their stage, this is a positive sign of improvement for the stock market.

We observe the same in the percent of stocks trending back above their longer-term trends. There was a 16% expansion in the stocks in the S&P 500 index trending above their 200 day moving average. The longer-term trend indicators are slower to respond, but this is more evidence of positive directional movement.

This is happening at a time when many investor sentiment indicators suggest fear has been driving stocks recently. A simple example is the Fear & Greed Index, which reached “Extreme Fear” a week ago.

CNN FEAR GREED INDEX SENTIMENT

As a portfolio manager for the past two decades, I have observed investor sentiment oscillate between fear and greed, but as a contrarian pendulum. Most investors feel the wrong feeling at the wrong time.

  • After prices rise, investors get more optimistic as they extrapolate the recent gains into the future expecting the gains to continue.
  • After prices fall, investors fear losing more money as they extrapolate the recent losses into the future expecting them to get worse.

What happens, though, is market trends move in multiple time frames of cycles up and down. Prices can overreact to the upside and downside and the majority of investors seem to get it wrong.

The level and direction of implied volatility is an indication of investor sentiment. I’ve shared my observations of the volatility expansion and noted some volatility contraction yesterday. So far, the volatility expansion has reversed to contraction, so the expected volatility as implied by options prices now suggests the market expects lower volatility in the weeks ahead.

VIX VOLATILITY CONTRACTION EXPANSION ASYMMETRIC RISK HEDGE ASYMMETRY

But, just as I pointed out on September 25th in VIX level shows market’s expectation of future volatility implied volatility can get it wrong. I pointed out then the implied volatility was very low signaling to me the market may have been wrong to expect such low future volatility, so it can reverse back up again.

In summary, today was a strong upward momentum day for the stock market and most stocks participated in the uptrend. After sharp declines like we’ve seen this month, the stock market sometimes reverses up like this into an uptrend only to reverse back down to test the low. After the test, we then find out if it breaks down or breaks out.

One day doesn’t make a trend, but for those who are in risk taker mode with stocks, so far, so good.

Observations of the stock market decline and volatility expansion

Observations of the stock market decline and volatility expansion

On September 25th I shared in VIX level shows market’s expectation of future volatility when I pointed out a low level of expected volatility as implied by the VIX index.

I said:

The current level of the VIX index has settled down to a lower historical level suggesting the market expects the future range of the price of the S&P 500 to be lower. Below is the current level relative to the past year.

I went on to explain my historical observations of volatility cycles driven by investor behavior:

The VIX Index is intended to provide a real-time measure of how much the market expects the S&P 500 Index to fluctuate over the next 30 days. The VIX Index reflects the actual order flow of traders

Since investors tend to extrapolate the recent past into the future, they usually expect recent calm markets to continue and violent swings to persist.

After the stock market declines and volatility expands, investors extrapolate that recent experience into the future and expect volatility to continue. Sometimes it does continue, but this time it gradually declined as the price trend became calmer.

When markets have been calm, traders and investors expect volatility to remain low. Before February, the VIX implied volatility had correctly predicted low realized volatility for months. But, both realized and expected volatility was so low that many investors were shocked when stock prices fell sharply, and volatility expanded.

When the market expects volatility to be low in the next 30 days, I know it could be right for some time. But, when it gets to its historically lowest levels, it raises situational awareness that a countertrend could be near. It’s just a warning shot across the bow suggesting we hedge what we want to hedge and be sure our risk levels are appropriate.

I shared the chart below, showing implied volatility at the low end of the cycle over the past year:

Since that date, we’ve indeed witnessed a volatility expansion of more than 90% in the VIX index and a decline in the S&P 500 stock index over -6%.  Implied volatility has expanded and stocks declined. As implied volatility is now starting to contract, below we can see the recent expansion as it trended from 12 to 24. Today its back to its long-term average of 20.

Stock market indexes, both U. S. and international, have declined 6 – 7% from their highs.

At this point, this has been a normal short-term cycle swing in an ongoing uptrend that is frequently referred to as a “correction.”

To be sure, we can see by looking at the % drawdowns in the primary uptrend that started in March 2009.

Markets cycle up and down, even within overall primary uptrends. As we see over a nine-year period, the current decline is about average and half as deep as the largest declines since 2009.

You can probably see what I meant by situational awareness of the markets cycles, trends, and volatility levels.

It isn’t enough to just say it or write about it. My being aware of the situation helps me to do what I said, which is worth repeating:

But, when it gets to its historically lowest levels, it raises situational awareness that a countertrend could be near. It’s just a warning shot across the bow suggesting we hedge what we want to hedge and be sure our risk levels are appropriate.

As far as the stock market condition, I like to see what is going on inside. Just as volatility swings up and down in cycles, so do price trends. As I’ve pointed out before, I observe prices swinging up and down often driven by investor behavior. For example, many investors seem to oscillate between the fear of missing out and the fear of losing money.

“The less the prudence with which others conduct their affairs, the greater the prudence with which we must conduct our own.” – Warren Buffett

One visual way to observe the current stage is the breadth of the stock market as I shared last week in The Stock Market Trend. Below is the percent of stocks in the S&P 500 index trending above their 50 day moving averages often used as a short-term trend indicator. This is a monthly chart since 2009 so we can see how it oscillates up and down since the bull market started. At this point, the number of stocks falling into short-term downtrends is about what we’ve seen before.

stock market breadth asymmetric risk

The risk is: this continues to be an aged old bull market, so anything is possible. That is why my focus every day is situational awareness. But, there is always a risk of a -10% or more decline in the stock market, regardless of its age or stage.

The good news is, we’ve now experienced some volatility expansion, stocks have now pivoted down to the lower end of their cycles, so maybe volatility will contract and stock prices resume their uptrend.

We’ll see.

All that is left to do is observe, be prepared, and respond tactically as it all unfolds.
