Performance of Growth & Value Stocks

Although many academics argue that value stocks outperform growth stocks, the returns for individuals investing through mutual funds demonstrate a near match. 

Introduction

A 2005 study Do Investors Capture the Value Premium? written by Todd Houge at The University of Iowa and Tim Loughran at The University of Notre Dame found that large company mutual funds in both the value and growth styles returned just over 11 percent for the period of 1975 to 2002. This paper contradicted many studies that demonstrated owning value stocks offers better long-term performance than growth stocks. 

The studies, led by Eugene Fama PhD and Kenneth French PhD, established the current consensus that the value style of investing does indeed offer a return premium. There are several theories as to why this has been the case, among the most persuasive being a series of behavioral arguments put forth by leading researchers. The studies suggest that the out performance of value stocks may result from investors’ tendency toward common behavioral traits, including the belief that the future will be similar to the past, overreaction to unexpected events, “herding” behavior which leads at times to overemphasis of a particular style or sector, overconfidence, and aversion to regret. All of these behaviors can cause price anomalies which create buying opportunities for value investors.

Another key ingredient argued for value out performance is lower business appraisals. Value stocks are plainly confined to a P/E range, whereas growth stocks have an upper limit that is infinite.  When growth stocks reach a high plateau in regard to P/E ratios, the ensuing returns are generally much lower than the category average over time. 

Moreover, growth stocks tend to lose more in bear markets.  In the last two major bear markets, growth stocks fared far worse than value.  From January 1973 until late 1974, large growth stocks lost 45 percent of their value, while large value stocks lost 26 percent. Similarly, from April 2000 to September 2002, large growth stocks lost 46 percent versus only 27 percent for large value stocks. These losses, academics insist, dramatically reduce the long-term investment returns of growth stocks.

However, the study by Houge and Loughran reasoned that although a premium may exist, investors have not been able to capture the excess return through mutual funds.  The study also maintained that any potential value premium is generated outside the securities held by most mutual funds.  Simply put, being growth or value had no material impact on a mutual fund’s performance.

Listed below in the table are the annualized returns and standard deviations for return data from January 1975 through December 2002.

Index                              Return                         SD      

S&P 500                            11.53%                     14.88%

Large Growth Funds         11.30%                     16.65%

Large Value Funds             11.41%                    15.39%

The Hough/Loughran study also found that the returns by style also varied over time.  From 1965-1983, a period widely known to favor the value style, large value funds averaged a 9.92 percent annual return, compared to 8.73 percent for large growth funds. This performance differential reverses over 1984-2001, as large growth funds generated a 14.1 percent average return compared to 12.9 percent for large value funds.  Thus, one style can outperform in any time period.

However, although the long-term returns are nearly identical, large differences between value and growth returns happen over time.   This is especially the case over the last ten years as growth and value have had extraordinary return differences – sometimes over 30 percentage points of under performance. 

This table indicates the return differential between the value and growth styles since 1992.

Between the third quarter of 1994 and the second quarter of 2000, the S&P Growth Index produced annualized total returns of 30 percent, versus only about 18 percent for the S&P Value Index.  Since 2000, value has turned the tables and dramatically outperformed growth.  Growth has only outperformed value in two of the past eight years.  Since the two styles are successful at different times, combining them in one portfolio can create a buffer against dramatic swings, reducing volatility and the subsequent drag on returns. 

Assessment

In our analysis, the surest way to maximize the benefits of style investing is to combine growth and value in a single portfolio, and maintain the proportions evenly in a 50/50 split through regular rebalancing.  Research from Standard & Poor’s showed that since 1980, a 50/50 portfolio of value and growth stocks beats the market 75 percent of the time.

Conclusion

Due to the fact that both styles have near equal performance and either style can outperform for a significant time period, a medical professional might consider a blending of styles.  Rather than attempt to second-guess the market by switching in and out of styles as they roll with the cycle, it might be prudent to maintain an equal balance your investment between the two.

TRADITIONAL INVESTMENT PORTFOLIO DIVERSIFICATION MODEL: Routed by Larry Fink CEO of BlackRock?

BREAKING NEWS – MARKET VOLATILITY

By Staff Reporters

***

***

US stocks nosedived on Thursday, with the Dow tumbling more than 1,200 points as President Trump’s surprisingly steep “Liberation Day” tariffs sent shock waves through markets worldwide. The tech-heavy NASDAQ Composite (IXIC) led the sell-off, plummeting over 4%. The S&P 500 (GSPC) dove 3.7%, while the Dow Jones Industrial Average (^DJI) tumbled roughly 3%. [ongoing story].

So, does the traditional 60 stock / 40 bond strategy still work or do we need another portfolio model?

***

The 60/40 strategy evolved out of American economist Harry Markowitz’s groundbreaking 1950s work on modern portfolio theory, which holds that investors should diversify their holdings with a mix of high-risk, high-return assets and low-risk, low-return assets based on their individual circumstances.

While a portfolio with a mix of 40% bonds and 60% equities may bring lower returns than all-stock holdings, the diversification generally brings lower variance in the returns—meaning more reliability—as long as there isn’t a strong correlation between stock and bond returns (ideally the correlation is negative, with bond returns rising while stock returns fall).

CORRELATION: https://medicalexecutivepost.com/2024/10/27/correlation-diversification-in-finance-and-investments/

For 60/40 to work, bonds must be less volatile than stocks and economic growth and inflation have to move up and down in tandem. Typically, the same economic growth that powers rallies in equities also pushes up inflation—and bond returns down. Conversely, in a recession stocks drop and inflation is low, pushing up bond prices.

***

  • But, the traditional 60/40 portfolio may “no longer fully represent true diversification,” BlackRock CEO Larry Fink writes in a new letter to investors.
  • Instead, the “future standard portfolio” may move toward 50/30/20 with stocks, bonds and private assets like real estate, infrastructure and private credit, Fink writes.
  • Here’s what experts say individual investors may want to consider before dabbling in private investments.

It may be time to rethink the traditional 60/40 investment portfolio, according to BlackRock CEO Larry Fink. In a new letter to investors, Fink writes the traditional allocation comprised of 60% stocks and 40% bonds that dates back to the 1950s “may no longer fully represent true diversification.

Asset Allocation Methods for Physician-Investors

What’s Old … is New Again?

By Dr. David Edward Marcinko; MBA, CMP™

Publisher-in-Chiefdem23

Asset allocation policies, incorporating the risk/return fundamental equation, have traditionally been classified under the following approaches: Principal Stability and Income, Income, Income-Oriented, Balanced, Growth, and Aggressive Growth.

Traditional Concepts

In all forms of traditional asset allocation and diversification policy approaches, the physician-investor is presumed to diversify within the chosen asset class in order to reduce the potential for specific or unsystematic risk.

Principal stability and income approach

Objective: Income, liquidity, and stability of principal.

Investment: Shorter-term fixed income securities with a large concentration in money market exposure to enhance liquidity and price stability. Accounts tend to maintain cash equivalent reserve balance of 30–50% of the portfolio.

Income approach

Objective: Maximum income.

Investment: 100% fixed income exposure.

Income portfolios arise from the traditional notion that an investor should spend only income and reinvest capital gains. Sometimes this is a legal requirement, as in a trust that has an income beneficiary distinct from the principal beneficiary.

Income-oriented approach

Objective: Income and some capital growth.

Investment: Accounts tend to maintain 15–35% in equity investments; balance of investment in fixed income.

Income and growth approach

Objective: Capital growth and income using a balanced approach to limit volatility.

Investment:  Accounts tend to maintain 45–65% equity exposure; balance of investment in fixed income.

Income and growth portfolio policies generally refer to both the fixed income and equity portions of the portfolios. Because of the income bias, the overall stock portion of the portfolio will usually have a dividend yield greater than the market yield. This method allows the portfolio manager to invest in some no- or low-dividend yielding issues.

Growth approach

Objective: Capital growth with income as a secondary objective.

Investment: Accounts tend to maintain between 65%–85% equity exposure; balance of investment in fixed income, usually cash reserves.

Aggressive growth approach

Objective: Long-term capital growth.

Investment: Accounts maintain 100% equity exposure. Exposure to variety of equity types normal (small capitalization, international, emerging markets, etc).

Assessment Of course, the above is much more accurate during stable economic times, than it is today; don’t you think? Are newer concepts required today … or is past … prologue.
