The surge in technology stocks is creating extreme market concentration effects

June 5, 2023

The strong headline FT Wilshire returns do not reflect market undercurrents

Market Navigation

Exhibit 1 shows the return profile for the FT Wilshire 5000 since the start of last year, showing how it has maintained an upward trajectory from the low reached last October. However, the 8.8% return for 2023 YTD (through to the end of May) belies the picture of a significant bifurcation between the winners and losers materializing below the surface.

The reality is ex the technology sectors the market has delivered a negative return YTD in 2023

Exhibit 2 compares the profile of the return for the headline FT Wilshire 5000 index YTD (red) versus the return of the FT Wilshire 5000 ex technology sectors (blue). Ex technology, the index has posted a negative -1.2% return YTD and shows a loss in momentum in Q2.

The tech sectors have been the only sectors delivering a positive contribution this quarter

Exhibit 3 displays the sector weighted performance contributions to aggregate market returns for both Q2to date (dark blue) and YTD (light blue). The AI fueled rally in the tech sectors has seen them dominate return contributions over both periods.

The rally in the tech stocks has created an extremely concentrated market

Exhibit 5 shows the combined weighting of the top 10 stocks within the FT Wilshire 5000 index over three time periods. The current combined weighting of 25.9% exceeds the level reached ten years ago and importantly the 20.3% weighting attained at the peak of the Technology, Media, and Telecoms (TMT) bubble in early 2000.

The greatest dependence on the top 10 stock return contributions this century

Exhibit 6 compares the return contribution generated by the top 10 stocks and compares them to the respective aggregate market returns. In the final year of the TMT bubble the market returned 24.1% with the top 10 stocks contributing 9% (over 1/3rd)of the aggregate return. So far in 2023 the market has returned 8.8% with the top 10 stocks contributing 8.4% (95%) of the aggregate return. In this respect the market is delivering the most concentrated returns this century.

Key inflection points in market behavior in 2023

May 8, 2023

2023 has witnessed some key inflection points and reversals in market behavior compared with the 2022

Market Navigation

Narrowing of market breadth

2023 has witnessed some key inflection points and reversals in market behavior compared with the 2022. One of the most notable shifts has been the resumption of deteriorating market performance dispersion. Exhibit 1 shows that 2022 saw the equally-weighted FT Wilshire 5000 significantly outperform the market cap weighted index but 2023 has seen this pattern reversed.

The median stock has also started to lag the top 10 stock return

Another gauge of market performance dispersion is the comparison between the return of the median stock with that of the aggregate return of the top ten stocks. Exhibit 2shows that 2022 saw the median stock outperform by c.10% but so far 2023 has seen a significant reversal with the top 10 stocks outperforming by more than 20%.

A major reversal in style rotation

Another key dynamic of market rotation in 2023 has been the reversal in Style performance.

A rollercoaster Q1 with the Tech rally trumping Bank angst

April 7, 2023

The +7.3% return in Q1 was delivered in three distinct phases

Market Navigation

Q1 returns were a function of 3 phases -A goldilocks rally in January (reflecting optimism that a recession would be avoided, and the Fed were almost done) followed by a sharp decline (from the start of February to mid-March) driven by concerns over both a hawkish Fed and bank contagion angst. Finally, late March saw a strong rally as the 'fear trade' dissipated.

Exhibit 1: The return for the FT Wilshire 5000 index

Q1 saw US banks underperform regional peers following the SVB collapse

The collapse of Silicon Valley Bank (SVB) in early March generated global contagion angst resurrecting 2008 GFC redux risk aversion in markets. Exhibit 2 shows that US banks saw the largest relative performance decline compared to other regions in Q1.

However, declining real yields and interest rate expectations buoyed risk appetite

The market response to heightened bank contagion risk was to price in a big decline in year-end interest expectations (reflected in the decline in 2-year bond yields) and a weakening in real yields. Once contagion angst started to dissipate by mid-March, easing financial conditions became the key driver behind the subsequent rally in risk appetite that saw the FT Wilshire 5000 post a +2.7% return for the month.

The rally in the Technology and the Growth style were the key features of Q1 performance

Rather than the emergence of bank contagion concerns, the key feature of Q1 performance was the strength of the recovery in Technology stocks. Exhibit 4 shows the relative performance of the technology sector and the relative performance of the growth style versus value. The performance of technology and growth style (long duration equity trades) is closely correlated to movements in US real yields. The positive inflection in Q1 was connected to signs that US real yields had peaked.

The dominance of the tech sector contribution in Q1 a mirror image of the 2022 profile

Exhibit 5 shows the sector-weighted performance contributions (the combined impact of sector weight and sector performance) for the FT Wilshire 5000 for Q1 vs the whole of 2022. The combined contributions for the technology and digital information sectors in Q1 accounted for the majority of the 7.3% for the index. This is a mirror opposite of the negative contributions they generated in 2022.

It can also be seen that the negative contribution for financials (this includes banks) was relatively small in Q1.

The Risk Off move in February had a different dynamic compared to those of 2022

March 2, 2023

While the FT Wilshire 5000 adopted a risk off tone in February…

Market Navigation

Having rallied in January on optimism that a recession would be avoided, the release of surprisingly strong labor market data forced the market to reappraise the trajectory of interest rates (dispelling any notion of them nudging lower later this year).This generated a cautious risk off tone that pushed the FT Wilshire 5000 -2.4% lower in February. However, the index is still up 4.4% YTD.

Exhibit 1: Risk aversion came to the fore in February driven by a rise in market interest rate forecasts

Source: Wilshire. Data as of February 28, 2023.

… the drawdown had a different dynamic compared to other recent pull backs. Here are 4 examples:

1 - Despite market weakness the technology sector leadership persisted

A key feature to the 2022 drawdown was the persistency of the decline in technology stocks. Interestingly, the February risk off move saw the technology sector outperform, delivering a positive sector weighted contribution to return (see Exhibit 2). In fact, year to date the technology and digital information and sectors have been the dominant positive contributions to aggregate returns. This is a mirror opposite to the 2022 dynamic.

Exhibit 2 : Sector weighted contributions to aggregate returns - YTD and February 2023

2 - The rotation to the Growth style (v Value) also persisted in February.

The positive inflection in the performance of the FT Wilshire Large Cap Growth index relative to Value that started in January persisted in February. This is a reversal of the 2022 dynamic (Exhibit 3). This rotation has occurred despite the rise in bond yields and real yields in February - these were key drags on highly valued Growth stocks in 2022.

Exhibit 3: Growth v Value style performance continues to inflect higher.

3 - A change in market dispersion dynamics in 2023 - the shift back to the dominance of the few.

Exhibit 4 compares the performance of the top 10 stocks in the FT Wilshire 5000 to the performance of the median stock to gauge the degree of performance dispersion. 2022 saw the median stock outperform the top 10 stocks implying a widening of dispersion. However, 2022 year-to-date has seen the opposite occur with the top 10 stocks significantly outperforming the median stock. This narrowing of dispersion has marked the return to the dominance of the few that characterized the market prior to 2022.

4 - The 2023 YTD returns have been driven by a PE expansion - the opposite pattern to 2022

Exhibit 5 decomposes market returns drivers into the contribution from changes to dividends, changes to EPS forecasts and changes to valuation. In the case of the US market, over the last 12 months the negative return was mainly attributable to the significant decline in PE valuation (grey bar). In 2023 the opposite has occurred with the positive return been driven by the expansion in the PE multiple.

Two distinct phases to the recovery in markets since mid-October

February 3, 2023

The FT Wilshire 5000 has appreciated 14.5% from the mid-October low

Market Navigation

Anticipation of a pivot in the degree of Fed hawkishness was the catalyst behind the recovery in risk appetite that commenced in mid-October last year. This positive momentum continued in January producing a return of 6.9% for the FT Wilshire 5000 for the month. From the mid-October low, the FT Wilshire 5000 had appreciated 14.5% to the end of January.

However, the rally can be dissected into two distinct phases

Exhibit 2 breaks the rally in the FT Wilshire 5000 since mid-October into two phases (October to December versus January). In the first phase, the rally was still defensive in nature represented by the marked outperformance of the Value style. By contrast, January saw a similar return for the market but this time it was driven by the outperformance of the Growth style.

Exhibit 2: A rotation to the Growth Style in January

The decline in real yields has contributed to the rally in the Growth style

Exhibit 3 shows relative performance of the FT Wilshire large Cap Growth versus Value and the US 10yr TIP real yield inverted. Style rotation responds to inflections in the real yield. The decline in the real yield in January has contributed to the Growth style outperforming the Value style by 5.7%

Growth benefitted from the contribution from 4 sectors in January

Exhibit 4 compares the sector weighted contributions to the returns for the Growth and Value style indexes in January. Growth benefitted significantly  from the larger respective contributions generated by four sectors - Digital Information, Technology, Consumer Goods and Transportation. These tend to be seen as long duration growth sectors that respond positively to declining real yields.

2022 performance review: Six key observations from an ‘annus horribilis’

January 5, 2023

The FT Wilshire 5000 delivered the 4th largest annual drawdown since 1970

The almost 6% decline in December resulted in the FT Wilshire 5000 registering a decline of -19% for 2022. This constitutes the fourth largest annual drawdown since the inception of the index in 1970.

Markets and risk aversion responded to a perfect storm of war (Ukraine), inflation, real income and supply chain shocks and a rapid rotation to restrictive financial conditions just as economies were recovering from the COVID impact - all making 2022 an annus horribilis.

A lack of diversification opportunities

What made 2022 particularly difficult was the lack of diversification opportunities. For example, Exhibit 2 shows that 2022 was the first time in 40 years that both bonds and equities delivered simultaneous negative returns.

Two sectors contributed almost half of the aggregate decline in US equities

Exhibit 3 shows the ranked FT Wilshire 5000 sector-weighted performance contributions for 2022. Almost half of the aggregate decline in the FT Wilshire 5000 is accounted for by the scale of negative contributions delivered by the Digital Information and Technology sectors.

The other key market dynamic was the rotation away from Growth towards Value style

Exhibit 4 depicts the -25.1% underperformance of the Growth style relative to Value in 2022. This has effectively unwound the rotation to Growth that occurred during the immediate aftermath of the COVID pandemic.

An important driver of underperformance of the Growth style was the negative valuation impact of rising real yields in 2022.

Exhibit 5 examines the sector-weighted contributions for both the Growth and Value style indices. Value benefitted from a larger positive contribution from the energy sector compared to the Growth Style. It also benefitted from not incurring the scale of negative contributions in the digital information, technology, and consumer goods sectors.

2022 saw an improvement in performance dispersion

Comparing the performance of the top 10 stocks by market cap (equally weighted) to the performance of the median stock in the FT Wilshire 5000 index is a useful gauge of performance dispersion. Exhibit 6 shows the scale of reversal in dispersion from 2021 to 2022. In 2021, median stock performance significantly lagged the return delivered by the top 10 stocks (negative dispersion). 2022 saw the median stock outperform delivering an improvement in dispersion characteristics.

October saw US equities rally on speculation the Fed might change tack

November 2, 2022

The FT Wilshire 5000 rallies 8.2% in October

Market Navigation

Having fallen sharply over the prior four-week period the FT Wilshire 5000 started to inflect sharply higher from mid-October closing out the month with a +8.2% return. There were two principal catalysts behind the recovery in risk appetite. The first was the market registered as significantly oversold in mid -October, reaching levels that typically see a subsequent rebound. The second catalyst was speculation that the Federal Reserve was becoming increasingly concerned about tightening too aggressively given mounting recession headwinds.

Exhibit 1: A robust recovery in the latter half of October

Source: Wilshire. Data as of October 31, 2022.

October saw a continued preference for Value vs Growth style

 

A key attribute of the recovery in risk appetite was the notable preference for Value over Growth as measured by the FT Wilshire 5000 style indexes. In October the Large Cap Value style index delivered a return of 11.6% while the Large Cap Growth style index only appreciated 4.2%. This rotation has been a dominant theme through the course of 2022 with Value outperforming Growth by 21.3% year to date.

Differentiating bear market rallies vs meaningful inflection points

November 2, 2022

Bear markets are not linear – they typically witness numerous rallies

Market Navigation

From January 3rd to the recent low on October 14, the the FT Wilshire 5000 had registered a drawdown of -25.9% the sixth largest since 1980. The key observation about bear markets is that they are not linear – in fact they often move in a sawtooth manner marked by numerous bear market rallies. This has been observable in the trajectory of the FT Wilshire 5000 returns this year (see chart below). Bear market rallies reward the ‘sell the bounce’ discipline, the antithesis of ‘buy the dip’.

Exhibit 1: Bear markets typically see numerous tradeable rallies

Source: Wilshire and Refinitiv. Data as of October 31, 2022

Just under half the days in a bear market register positive returns

To reiterate the point that bear markets are not linear we have measured the trading pattern of bear markets (lasting more than three months) registered by the FT Wilshire 5000 since 1980. This shows that around 45% of the trading days witness upward moves. The bear market is driven by the compounding effect of the average daily move in a down day being -1.4% vs the average daily move on an up day being +1%.

Exhibit 2: The trading pattern of bear markets

How to differentiate a bear market rally from a sustained inflection point?

If bear markets witness numerous bear market rallies, how can we identify when a rally is marking a nadir followed by a sustained positive move?

One answer to this is to wait for key technical signal confirmation. The ‘Golden Cross’ (the positive intersect of the 50-day moving average with the 200-day moving average where the latter has bottomed) is a useful tool aiding the identification of major market inflection points.

Q3 witnessed a dramatic "U-turn" in risk appetite

October 3, 2022

The rapid reversal in risk appetite in Q3 has produced a retest of the June lows

Market Navigation

August witnessed a significant reversal in risk appetite mid-month in response to a succession of hawkish Fed guidance. This brought an end to the +18.6% two-month rally (and optimism) that started on June 16 and peaked on August 16. Since the mid-August peak, the FT Wilshire declined -16.7% over the remainder of the quarter to produce a -4.4% return for the three-month period. The strength of the rotation to risk aversion has now driven the index below the low point reached in mid-June.

One of the largest six-week drawdowns since 2006

Exhibit 2 puts the scale of the drawdown in US equities over the latter half of Q3 into perspective - showing that it is almost a three standard deviation event. Outside of the GFC and COVID sell offs, this is one of the largest six-week drawdowns since 2006.
