In our process, we consistently analyze leadership trends of Large Cap Value vs Growth indexes. While our focus in this piece is on the iShares S&P 500 Value Index (IVE) vs the iShares S&P 500 Growth Index (IVW), the results are similar for investors who choose to utilize Russell 1000 indexes (Value – IWD and Growth – IWF) instead.

We will discuss three important observations which lead to critical questions for investors:

  • Large Cap Value Index vs Growth Index relative performance can be significant to portfolio returns. One lesson we draw from history is that the portfolio default overweight should be to Value indexes.
  • Value vs Growth leadership often runs in long cycles. Through the end of 2015, Growth had outperformed Value by an astounding 3.08% per year for the trailing 5 years. Growth won the annual performance derby 4 of the 5 years and 7 of the past 9 years.
  • Leadership trends have shifted often over time. Can we identify markers that may indicate an impending reversal of Value vs Growth leadership?

Why investors should focus on Value vs Growth ETFs

Many investors may choose to simply invest in the S&P500 alone, instead of gaining exposure to the S&P 500 stocks through a combination of an S&P Value and S&P Growth index.   Due to our extensive investment process, we find there is benefit to holding exposure to the underlying Growth and Value indices for many of our portfolios.  By holding the components, as opposed to the aggregate, we are able to add value by using two levers instead of one.

There are many ETFs available that allow investors and traders to establish positions in possible market leaders and against projected market laggards. Some options in the ETF landscape include leveraged ETFs such as the Direxion Daily Bull and Bear 3x ETFs (SPXL and SPXS), but also arcane sub-indexes such as iShares Exponential Technologies (XT). We prefer to focus instead on areas where we feel long term value can be added.  This allows us to identify ETFs that can materially enhance longer term returns, without forcing us to take on unacceptable risks.

We do not need to limit the TOPS portfolios to simply using the broadest indexes, such as the S&P 500, because the next level of specialization is simply dividing the index into its Growth and Value components. Our research suggests there may be an advantage to overweighting portfolios to Value over time. Is that because “cheaper” stocks always do better than “faster earnings growth” stocks? Well, no. The key to this performance record may be revealed in the methodology used by S&P to build the indexes.

Visiting the “sausage factory” gives us some worthwhile insights

There is an old adage that “Laws are like sausages, it is better not to see them made” and the same may be true for equity indexes. However, we believe it is important to understand how Standard & Poor’s manufactures its S&P 500 Value and Growth indexes.

In the first step, S&P uses a short list of Value and Growth characteristics to rank every stock in the S&P 500.  They then assign 33% of the S&P 500 companies to the S&P Value Index Value and 33% to the S&P Growth. Next, the remaining 34% is assigned to both V and G, with each stock’s capitalization split according to whether it ranks higher in the V rankings or the G rankings. It is important to understand that this results in indices created on relative rankings rather than a “pure” focus on absolute characteristics.

The attributes used for Value are not surprising: ratios of book value to price, earnings to price and sales to price. On the other hand, many “growth” managers would not necessarily rely on the measures used to select Growth equities: sales growth, the ratio of earnings change to price, and price momentum. You may have noticed that actual or expected EPS growth is not on the Growth list.

The net effect of this is the S&P Value vs Growth index methodology boils down to:

1) Lower valued vs higher valued

2) Lower price-momentum vs higher price-momentum.

If companies with higher EPS growth rates are undervalued as a class, they can actually represent a significant portion of Value, rather than Growth. At any rate, longer term “reversion to the mean” tendencies clearly favor lower value (which can improve) over faster price momentum (which can worsen).

S&P 500 Value returns over the long term are much better than S&P 500 Growth

The result of the mean-reversion biased stock selection methodology clearly shows in the very long term relative performance of Value vs. Growth. Examining returns for each decade, we see Value +7.8% over Growth per year in the 1970’s, +4.4% in the 1980’s, and +2.1% in the 2000’s. Only in the 1990’s (thanks to the technology stock momentum bubble) did Growth outperform over a decade, beating Value by +6.0% per year.

Despite periods of Growth outperformance, Value is well ahead when we take a truly long term perspective. Investors may thus consider their own bias: overweighting IVE versus IVW unless the inputs from your process favor a tactical overweight to Growth.

Recent Growth vs Value results run counter to the longer term trends

The following chart (courtesy of Yardeni research) shows periods of Growth outperformance (when the red line is rising) and Value leadership (a rising blue line).  Make no mistake, the chart demonstrates the S&P Value Index has been drubbed by S&P Growth over the past several years.

In fact, the point-to-point upward slanting red line from 1995 to May 2016 reveals a sizeable outperformance from Growth. Through May 2016, Growth is ahead of Value by annualized rates of +3.88%, +2.21% and +3.29% over the past 3, 5 and 10 year periods.

This might appear to refute our theme of Value leadership over time. However, just a small change in the starting point to May 1996 on the chart (thus establishing a 20 year measurement) reduces the Growth advantage to about 0.7% annually.

Another critical takeaway from this chart is that the 2015 peak level of Growth outperformance remains well below the 1999 Growth peak. As the remainder of the 1995-1999 Growth leadership spike falls out of the 20 year timeframe, Value is likely to reclaim the long term leadership title. We believe Growth’s peak-to-peak record of trailing Value further supports our opinion that investors should consider overweighting the S&P Value Index over time.

To conclude this leadership review, we note Growth’s leadership ended in 2000, then Value led into 2007 before the current Growth leadership cycle commenced. Is it ending now? Nobody knows, but year-to-date through May, Value (+5.31%) crushed Growth (+1.91%) by over 3%.

This cyclicality fits nicely with the TOPS strategic approach to active indexing which calls for taking a 1-3 year prospective view on an asset class or ETF before making any changes to portfolio allocations. An important tool for equity ETF analysis is analyzing each index’s price/earnings ratio versus its historic norms since 1995. We prefer to maintain heavier weightings to indexes that are toward the lower end of their historic range. From that perspective, the factors used by Standard & Poor’s sausage-making is complementary to our decisions as to which “sausage” to buy.

Extreme sector weight differentials are important to consider

Additional factors also come into play. Investors should pay attention to the sector weights of the underlying indexes. A recent paper written by Sam Stovall of S&P Global (May 2016 – What Drives Growth & Value?)  shows the sector composition of Value and Growth plays a large role in relative performance. For instance, the Technology sector always accounts for a much larger percentage of Growth than Value, while Financials are heavily skewed in the opposite direction. S&P’s research shows a positive 52% Tech correlation and negative 16% Financials correlation with Growth outperformance. Combining the correlations of the two sectors generates a coefficient of 73%, which Stovall notes is a pretty convincing result.

Currently, Tech is 31.5% of Growth and only 7.7% of Value, while Financials are 7.9% of Growth and 24.4% of Value. Thinking back to factors used by S&P to allocate companies to Value and Growth, it’s no surprise to see that higher-valued Tech will be in Growth and lower-valued Financials in Value. If an investor has a strong opinion about the future performance of those sectors, it could impact their portfolio positioning of Growth vs Value. Sector weights also help Value total returns relative to Growth, as dividend yields are generally higher for Value-overweight sectors including Financials, Energy, Utilities and Telecom.

While markers are in place, the timing of a leadership reversal cannot be forecasted

We believe a leadership reversal is inevitable but the exact timing is unforecastable. Markers in place include:

  • Mean reversion. Trees don’t grow to the sky and momentum stocks eventually falter. When that occurs, Value will take command of the performance derby.
  • Absolute valuations for Value are lower than for Growth, but both are above-average according to our research. Roughly 37% of Value market cap is in Financials and Energy, both of which have the potential for improved EPS comparisons (which would mean the current P/E is overstated). For Growth, 50% is in Tech and Consumer Discretion and both sectors have optimistic forward EPS expectations. Any EPS disappointment would leave the current P/E understated.
  • The cycle of Growth outperformance is stretched. Recent strong results from Value should be monitored closely, as it could be an early sign of a new cycle in favor of Value.

So, to answer the question posed by our title, a leadership reversal should not be surprising. When (not if) that occurs, investors may want to shift toward Value as the combination of longer term trends and cyclical leadership could be a solid plus for portfolio performance.
