"Is Momentum Still Relevant for Today’s Markets?" by Anthony Ng, Senior Lecturer

Published on

Presented at QuantCon Singapore 2016, Quantopian's quantitative finance and algorithmic trading conference, November 11th.

Despite being ‘discovered’ over 20 years ago, there is still confusion on what a momentum strategy entails and people ‘invest in momentum’. There are two generally accepted definitions of momentum in academic literature. In the quantitative equity investment sphere, momentum is frequently referred to as across securities or assets (cross-sectional or relative) and typically traded in a long-short or hedged manner. In futures trading, momentum is often referred to the past return of the security (time-series) and normally traded in a directional fashion.

Following from the above, we conducted an analysis on the performance of a momentum strategy of different asset classes: equity, fixed income, futures, and currencies. The study showed that both types of momentum are prevalent and persistent across all asset classes. Furthermore, as the correlations between the two types of momentum strategies and amongst the asset classes are quite low, substantial diversification benefit can be derived by combining them.

  4. 4. MOMENTUM Cross-Sectional Momentum. Jegadeesh and Titman (1993) Rank the cross-section of stocks each month based on their return over the past 6 mths Form decile portfolios each month Time Series Momentum. Moskowitz, Ooi and Pedersen (2012) Takes long or short position on an asset by only looking back at its own performance during the formation period, and not based on its relative rank across a cross-section
  5. 5. Value/Carry/Momentum FX/equity/commodity/interest rate Sharpe ratio, average 0.40 per asset class Maximum drawdowns 1.8x - 3.1x volatility Positive skew for value and momentum Negative skew for carry Sharpe ratio 1.4 *BAZ, JAMIL AND GRANGER, NICOLAS M.

  6. 6. Persistence in asset returns Buy assets that out-performed Sell assets that under-performed Negative auto-correlation for < 1-month and > 3-years Positive auto-correlation for 6-12 months Sample period: 1990 - 2015 *BAZ, JAMIL AND GRANGER, NICOLAS M.

  8. 8. TIME-SERIES MOMENTUM* 58 liquid futures contracts 12-month time series momentum, 1-month holding period Sample period: 1985 - 2009 Alpha 1.58% per month with respect to MSCI World Index, Fama-French (1993) and Carhart (1997) SML (Size), HML (Value) and UMD (Cross-Sectional Momentum) * TOBIAS MOSKOWITZ, YAO HUA OOI AND LASSE PEDERSEN, TIME SERIES MOMENTUM (2012)

  10. 10. TIME-SERIES MOMENTUM* Sharpe ratio > 1, 1985 - 2009 Sharpe ratio = 1.1, 1966 - 1985 MSCI World, Beta = 0.09 (t-stat, 1.89) SMB, Beta =-0.05 (t-stat, -0.84) HML, Beta = -0.01 (t-stat, -0.21) UMD, Beta = 0.28 (t-stat, 6.78) Only significant with UMD (MOM), the cross-sectional momentum factor * TOBIAS MOSKOWITZ, YAO HUA OOI AND LASSE PEDERSEN, TIME SERIES MOMENTUM (2012)
  11. 11. TIME-SERIES MOMENTUM AND VOLATILITY SCALING* Without scaling by volatility, time series and a buy-and-hold strategy offer similar cumulative returns, and their alphas are not significantly different Cross-sectional momentum offers a higher alpha than unscaled (scaled) time series momentum * ABBY KIM, YIUMAN TSE, JOHN WALD, TIME SERIES MOMENTUM AND VOLATILITY SCALING (2016)
