Momentum Investing Strategy Basics

The basic idea of momentum investing is intuitive. A stock or any other asset, that has been trending strongly for a while is likely to continue doing so a little while longer. That is the core concept, rest are details.

Nobel Laurette economist Eugene Fama, who propounded the Efficient Market Hypothesis (EMH), described momentum as a “premier anomaly” and termed it a “pervasive” phenomenon. EMH states that as markets are efficient, therefore, past prices cannot predict future returns. Momentum strategies do exactly that, and has been doing so for more than 100 years.

There is no universal explanation as to why price momentum works. Potential explanations include investors tendency to initially under-react, and then over-react to news affecting stock prices – a behavioral bias often described as initial under-reaction and delayed over-reaction.

Momentum remains an extensively researched subject in finance which papers documenting evidence of momentum in stock prices dating almost a century back.

Academic research on Momentum Investing Strategy

Momentum is one of the most well researched topics in finance over the past 20 years. Hundreds of papers exits internationally, as well as in India, covering multiple countries and asset classes. We discuss some of the key papers below.

Seminal research by Jegadeesh & Titman

Seminal research on momentum was conducted by Jegadeesh & Titman (1993).

Using data from 1965 through 1989 they observed that winning stocks on the NYSE & AMEX over past 6 to 12 months continued to outperform losing stocks on average over next 6 to 12 months by approximately 1% per month.

Following this paper, their findings have been separately confirmed by many other academic studies, some even going back to the 19th century.

Narshiman Jegadeesh was an IIT/IIM graduate who earned his PhD at Columbia University.

In 1993, Jegadeesh, along with Sheridan Titman (UCLA) published a study showing that intermediate term momentum can be used to generate excess portfolio returns. This paper was described as a “bombshell” against those who glorified the Efficient Market theory.

52 week High-Low strategy

Similar study was performed by George and Hwang (2004) who developed a strategy that selects stocks based on the ratio of the current price relative to its past 52-week high.

Using data from January 1963 to December 2001 they showed that the long-short portfolio generates 0.45% excess returns per month, with the winner’s portfolio averaging 1.51%, about 50% more than the loser’s portfolio average return of 1.06%.

Momentum is Persistent and Pervasive

Following Jegadeesh & Titman’s seminal research, hundreds of studies have followed making momentum one of the most well researched topic in finance over the past 20 years

Geczy and Samonov (2012) showed that momentum has worked for US equities for 212 years all the way back to 1801!

Multiple researchers [Antonacci (2012), Asness (2013), King, Silver & Guo (2002)] have established that momentum works over a dozen asset classes and more than 40 countries.

No wonder, Fama & French dscribed momentum as a “premier anomaly” and a “pervasive” phenomenon.

The premier market anomaly is momentum… It has been the biggest embarrassment to the Efficient Market theory and I hope it goes away! 🙂

Dual Momentum Investing

Gary Antonacci published two papers [7, 8] and a book titled Dual Momentum Investing on multi-asset momentum. His Global Equity Momentum (GEM) strategy is based on 3 index funds – 1. Barclays US Aggregate Bond Index for bonds, 2. S&P 500 Index to represent US Equities & 3. ACWI – Ex US to represent Global Equities. The logic is simple: if equity returns are less than T-bills then invest in bonds, else choose between US & Global Equities based on Relative Strength.

Between 1974 & 2013, GEM returned 17.43% annually, compared to 12.34% for S&P500 and 8.85% for ACWI.

Momentum investing research in India

In the context of Indian stock markets, one of the most well-known study was published by IIM-Ahmedabad, where they computed the Fama-French and momentum factor returns for the Indian equity market for the October 1993 – December 2013 period.

Based on this study, the average annual return of the momentum factor was 21.9%; the average annual return on the value portfolio (HML) was 15.3%; that of the size factor (SMB) nearly 0%; and the average annual excess return on the market factor (MRP) was 11.5%.

Attribution analysis of ViniyogIndia 🚀 Momentum Portfolio

To interpret the sources of return for our strategy, we perform a regression analysis using Carhart 4 Factor model. The results are shown in the following table.
Factor exposure0.8560.6560.1070.1450.394
The above data shows that the strategy generates significant alpha that is statistically significant.

Monthly alpha or excess return for the strategy is 0.856%. This is generated using a combination of secondary factors and asset allocation strategies that tries to enhance momentum returns while reducing risks.

Additionally, standard factors, such market beta, momentum and value also add to the overall strategy returns. Returns from the size factor isn’t statistically significant.

It is important for the investors to understand the sources of return for their funds in order to appreciate the value provided by the fund manager, as in many cases managers fail to generate alpha despite charging hefty fees. What they generate instead are betas, which can be easily obtained by exposure to the standard risk factors.

In such cases where an analysis of the fund’s performance reveal that the manager isn’t generating any alpha, investors would be better off buying low cost index funds or ETFs which provide exposure to one or more of the betas such as value, momentum or size. In case of momentum for example, one such low cost fund is the UTI Nifty200 Momentum 30 Index Fund whcih basically mimics the Nify200 Momentum30 Index.
