Momentum Investing -

Introduction

Momentum Investing is a trading strategy that involves buying securities that have shown an upward price trend and selling those that have shown a downward trend. This approach is grounded in the belief that asset prices that are rising will continue to rise, and those that are falling will continue to fall. Many academic studies have demonstrated that momentum investing can generate significant returns, making it a popular strategy among traders and investors.

Understanding Momentum Investing

What is Momentum Investing?

Momentum investing refers to an investment style where investors:

Purchase assets (e.g., stocks, bonds) that are consistently rising in price.
Sell assets whose prices are consistently falling.

The core idea is to capitalize on existing market trends with the expectation that these trends will persist. This “buy high, sell higher” philosophy contrasts sharply with the traditional investment approach of “buy low, sell high.”

The Rationale Behind Momentum Investing

Trend Continuation: Investors believe that securities exhibiting strong performance will continue to perform well in the near future.
Market Psychology: Momentum investing leverages behavioral biases like herding, where investors follow the crowd, pushing prices further in the existing direction.
Delayed Reaction: Markets may not immediately price in new information, leading to trends that can be exploited.

Key Features of Momentum Investing

1. Time Frame

Short to Medium Term: Momentum strategies usually focus on short to medium-term trends, typically ranging from a few weeks to a year.

2. Performance Measurement

Relative Strength: Evaluating the performance of securities relative to others over a specific period.
Technical Indicators: Utilizing tools like moving averages, trend lines, and momentum oscillators.

3. Risk Management

Stop-Loss Orders: Setting predetermined price levels to exit positions and limit losses.
Diversification: Spread investments across multiple securities to mitigate risks.

4. High Turnover

Frequent Trading: Higher buying and selling frequency leads to increased transaction costs and requires careful consideration.

Jegadeesh and Titman (1993): Found that portfolios of past winners outperform past losers over 3 to 12-month periods.
Asness, Moskowitz, and Pedersen (2013): Demonstrated momentum profits across different asset classes globally.
