Clustered Volatility and the “Momentum Massacre”

 

“But, as with markets, in the ocean the interesting things happen not at the equilibrium sea level which is seldom realized, they happen on the surface where ever-present disturbances cause further disturbances. That, after all, is where the boats are.” ― W. Brian Arthur

 

Financial markets exhibit a temporal phenomenon known as clustered volatility. That is, the existence of periods of low volatility followed by periods of high volatility. Low volatility reigns supreme when the the outcome of the cumulative actions of market participants mutually benefits the majority. And, by extension, reaffirms the confidence the majority of market participants have in their forecast, “investment process”, algorithm or “analytical framework”  ― or, more crudely, heuristics that they use in making their trading or investment decisions. The majority continue to follow their “process” and among the minority that did not benefit in the run up all but the most stubborn gradually adapt their processes to implicitly or explicitly chase momentum. Low volatility begets low volatility.

 

High volatility often occurs when an external agent, such as President Trump tweeting about tariffs or the People’s Bank of China excessively tightening or loosening financial conditions, disrupts the seeming equilibrium in the market. All else being equal, which it never is, the impact of external agents on market volatility, however, tends to be fleeting. For example, the declining half-life of President Trump’s trade war related tweets impact on the US equity market.

 

A structural change in volatility generally occurs when some participants or a group of market participants alter their algorithm ― such as shifting from selling at the money puts to deep out of the money puts ― or investment process or by the entry of entirely new participants with a novel agenda ― like the Bank of Japan buying up ETFs as part of its QE programme ― to the market.

The changing of algorithms or processes may, of course, be in response to the actions of external agents or the impact said actions had on the market. Regardless, this “updating” allows the first movers to  front-run or anticipate the behaviour of the majority, which in turn causes other investors to re-adapt. This adaptive behavior, if it successfully percolates and propagates, moves the market away from its seeming equilibrium and into a state of ‘chaos’. It is this process of re-adapting that tends to precipitate longer lasting bouts of higher volatility.

 

Robert F. Engle, the winner of the Nobel Prize in Economics in 2003,  formally defined this process of random periods of low volatility alternating with high volatility in financial markets as the the generalised autoregressive conditional heteroskedasticity (GARCH) process.  (Heteroskedasticity is where observations do not conform to a linear pattern. Instead, they tend to cluster.)

 

Momentum Massacre

 

From the Financial Times on 12 September 2019 (emphasis added):

 

“The stock market may appear tranquil again after a rollercoaster summer, but many analysts and investors are unnerved by violent moves beneath the surface, reviving memories of the 2007 “quant quake” that shook the computer-driven investment industry.

 

The FTSE All-World equity index has rallied almost 3 per cent already this month, clawing back some of August’s losses. However, many highly popular stocks suffered a sudden and brutal sell-off this week, a reversal that analysts have already dubbed the “momentum crash”.

 

The blow was particularly strong in the US, where strong-momentum stocks — those with the best recent record — tumbled 4 per cent on Monday, in the worst one-day performance since 2009, according to Wolfe Research. Only once before, in 1999, has such a rout afflicted momentum-fuelled smaller company stocks, according to investment bank JPMorgan.”

 

This is massive,” said Yin Luo, head of quantitative strategy at Wolfe Research. “This is something that we haven’t seen for a long time. The question is why it’s happening, and what it means.”

 

The flipside has been a dramatic renaissance for so-called “value” stocks — out-of-favour, often unglamorous companies in more economically sensitive industries. The S&P value index has climbed about 4 per cent this week and, compared with momentum stocks, enjoyed one of its biggest daily gains in a decade on Monday.

 

The chart below is the ratio of the S&P Growth index to the S&P Value index. We are struggling to find the “dramatic renaissance”.

Of course we are being more than a bit flippant. Nonetheless, we do not think it is time to completely drop momentum or growth stocks and load up on value stocks. Rather we think the market is in a transient phase where participants are updating their algorithms and processes to go beyond momentum.

 

Our prescription from June remains valid:

 

We are increasingly convinced that a barbell strategy should be applied today in managing equity exposures. With tech and other growth names on one side and value names and precious metals on the other. And if tech and growth continue to rally, investors should re-balance  regularly to avoid any lopsidedness in their portfolios.

 

The above has worked well in the recent “momentum massacre” and can continue to work well as long as uncertainty remains high and sentiment viciously waxes and wanes between optimism and pessimism. A slight adjustment to the above, however, is warranted as follows:

 

A barbell strategy should be applied today in managing equity exposures. With tech and other growth names on one side and value names and precious metals energy plays on the other.

 

Do Not Drop Momentum ― Not Completely Anyway

 

Dropping momentum or growth completely would be akin to calling the end of the transition away from actively managed portfolios to passively managed allocations that has accelerated since the Global Financial Crisis. Passive allocations are implicitly momentum seeking strategies. A strong secular trend is not upended by a 4 per cent move, it will take a crisis or a severe re-think of strategic asset allocation by the managers of the largest pools of capital to bring about an end to the trend.

 

The rise of passive investing, along with systematic volatility selling strategies, has contributed to the dampening of volatility since the Global Financial Crisis. A growing share of passive allocations, however, is somewhat like increasing leverage. As passive flows now make up the lion’s share of capital market flows, the actions of active investors are spread over a smaller segment of the investment universe. As the size of the active universe shrinks, in terms of what could be described as, in the case of stocks, free float market capitalisation minus passive allocations, the actions of active investors begin to have an exaggerated impact and give rise to higher volatility.

 

Simply put, the passive flows versus volatility curve is convex. Initially, increasing passive flows dampen volatility but beyond some hitherto unknown level increasing passive flows lead to higher volatility.

 

Why Energy Over Precious Metals?

 

Without delving into the geopolitics of it, the attacks on the Saudi Arabian oilfield should remind major oil consumers ― airlines, refiners, transportation companies and emerging economies such as India and China ― to review their energy security and hedging strategies. To balance future energy needs and to not become hostage to a rising geopolitical risk premium in the price of oil. This should lead to a rise in demand for oil at the margin; commodity prices are, of course, set at the margin.

 

The other angle is that if anything is going to take down the almighty bond bull market its going to be either: (1) fiscal spending by the G-7 governments of the like that we have never seen; or (2) a sharp and sustained increase in oil prices.

 

Lastly on energy, if Iran is, rightly or wrongly, shown to be the perpetrator of the attacks, China may have to reconsider it decision to purchase Iranian oil.

The Hawks Have Not Left the Building

 

“Difficulties are meant to rouse, not discourage. The human spirit is to grow strong by conflict.” – William Ellery Channing

 

“Very few negotiations are begun and concluded in the same sitting. It’s really rare. In fact, if you sit down and actually complete your negotiation in one sitting, you left stuff on the table.” – Christopher Voss

 

The Hawks Have Not Left the Building

 

A “typical feature of conflicts is that […] the intergroup conflict tends to be exacerbated and perpetuated by intragroup conflicts: by internal conflicts within each of the two contending parties. Even when there is growing interest on both sides in finding a way out of the conflict, movement toward negotiations is hampered by conflicts between the “doves” and the “hawks” –or the “moderates” and “extremists” –within each community”.  So wrote Herbert C. Kelman, the Richard Clarke Professor of Social Ethics, Emeritus at Harvard University, in Coalitions Across Conflict Lines: The Interplay of Conflicts and Between the Israeli and Palestinian Communities.

 

Kelman – renowned for his work in the Middle East and efforts to bring Israel and Palestine closer towards the goal of achieving peace in the Middle East – identifies, in the paper he authored in 1993, the “relationship between intergroup and intragroup conflict” as a key hurdle towards building coalitions across conflict lines. According to Kelman, “doves on the two sides and hawks on the two sides have common interests”. The hawks, unlike the doves, can pursue their interests without the need to coordinate with their counterparts on the opposing side. The hawks simply “by engaging in provocative actions or making threatening statements” reaffirm the enemy’s worst fears and embolden the hawks on the opposing side. The doves, on the other hand, “tend to be preoccupied with how their words will sound, and how their actions will look, at home, and with the immediate political consequences of what they say and do.” Therefore, the doves tend to take a more measured approach in communicating their views and underplay their side’s willingness to negotiate – the kind of behaviour that plays right into the hands of the hawks and reduces the effectiveness of the doves

 

Kelman’s recommendation to increase the chances of resolving a conflict by means of negotiation is to facilitate greater coordination between the doves on the opposing sides and minimise the involvement of the hawks.

 

The lessons from Professor Kelman’s work, we think, are highly relevant today. His insights provide a framework for determining the possibility of success in each round of negotiations between the US and China in resolving the on-going trade dispute.

 

Subsequent to the working dinner between President Trump and President Xi in Buenos Aires following the G20 summit, the headlines have focused on the temporary ceasefire in the trade dispute. President Trump has pledged to suspend the increase in tariffs on US dollars 200 billion of Chinese imports that was to go into effect on 1 January 2019 for a period of up to 90 days. In return President Xi has pledged that China will buy more US goods, ban exports of the opioid drug, and offered to reconsider the Qualcomm-NXP merger that failed to receive regulatory approval in China earlier in the year.

 

The three-month period, before the suspension of the tariff increase lapses, provides the two-sides a window of opportunity to initiate a new round of talks to tackle some of the more sensitive issues surrounding the trade dispute, including ownership and access to technology and intellectual property.

 

Despite the announcements lacking details, capital markets have reacted positively to the news of the temporary ceasefire and the Chinese yuan, on Monday, posted its largest single day gain since February 2016.

 

We are not surprised by the bare bones nature of the agreement following the meeting between President Trump and President Xi. The last minute inclusion of Peter Navarro, White House trade policy adviser and prominent China hawk, to the list of guests attending the working dinner was, at least to us, a clear signal that meaningful progress on trade relations during the meeting was unlikely. After all, Mr Navarro’s role in the Trump Administration, as The Atlantic puts it, is “to shepherd Trump’s more extreme ideas into reality, ensuring that the president’s convictions are not weakened as officials translate them from bully-pulpit shouts to negotiated legalese. He is the madman behind Trump’s “madman theory” approach to trade policy, there to make enemies and allies alike believe that the president can and will do anything to make America great again.”

 

Moreover, we do not expect a breakthrough in negotiations to materialise during the next round of talks between Washington and Beijing before the suspension of the increase in tariffs lapses. As long as hawks such as Peter Navarro and Robert E. Lighthizer continue to have President Trump’s ear our view is unlikely to change. If, however, the dovish members of the Trump Administration, such as Treasury Secretary Steve Mnuchin and Director of the National Economic Council Lawrence Kudlow, begin to take control of proceedings we would become much more hopeful of a positive resolution to the trade dispute.

 

For now, we see the temporary agreement between the two sides as providing much needed short-term respite for China. More importantly, we see President Trump’s offer of a temporary ceasefire without President Xi offering any concessions on sensitive issues, such as industrial policy, state funded subsidies and intellectual property rights, to be a symptom of the short-termism that seemingly besets democratically elected leaders without exception. Had the US equity capital markets not faltered recently and / or the Republicans not lost control of the House of Representatives, it is unlikely, we think, that President Trump would have been as acquiescent.

 

 

Liquidity Relief

 

In June in The Great Unwind and the Two Most Important Prices in the World we wrote:

 

“In the 362 months between end of May 1988 and today there have only been 81 months during which both the US 10-year treasury yield and the oil price have been above their respective 48-month moving averages – that is less than a quarter of the time.

 

Over the course of the last thirty years, the longest duration the two prices have concurrently been above their respective 48-month moving averages is the 25 month period between September 2005 and October 2007. Since May 1988, the two prices have only been above their respective 48-month moving averages for 5 or more consecutive months on only four other occasions: between (1) April and October 1996; (2) January and May 1995; (3) October 1999 and August 2000; and (4) July 2013 and August 2014.

 

Notably, annual global GDP growth has been negative on exactly five occasions since 1988 as well: 1997, 1998, 2001, 2009, and 2015. The squeeze due to sustainably high US interest rates and oil prices on the global economy is very real.”

 

We have updated the charts we presented alongside the above remarks and provide them below. (The periods during which both the US 10-year treasury yield and the oil price have been above their respective 48-month moving averages are shaded in grey in the two charts below.)

The sharp drop in oil prices in recent weeks ended the 10 month streak of the 10-year Treasury yields and oil prices concurrently trading above their respective 48-month moving averages.

 

The recent drop in oil prices has coincided with the Fed weighing up the possibility of changing its policy guidance language. Several members of the Fed have suggested, according to the minutes of the FOMC’s November policy meeting, a “transition to statement language that [places] greater emphasis on the evaluation of incoming data in assessing the economic and policy outlook”. If the drop in oil prices sustains the data is likely soften and compel the Fed to dial back its hawkishness. With the base effects from the Trump Tax Cut also likely to recede in 2019, there is a distinct possibility that the Fed’s policy will be far less hawkish in 2019 than it has been over the course of 2018.

 

Lower (or range bound oil prices) and a more dovish Fed (even at the margin) are the conditions under which oil importing emerging markets tend to thrive. Although it is still too early to be sure, if oil prices fail to recover in the coming few months and the Fed is forced into a more dovish stance due to softer data, 2019 might just be the year to once again be long emerging markets.
