The Concept of Momentum: Scientific and Theoretical Foundations
Momentum in financial markets refers to the continuation of price movement in a specific direction over a certain period. If a stock's price is rising rapidly, it is said to have upward momentum, and the opposite holds for declines. The scientific roots of momentum stem from prominent academic research such as Jegadeesh and Titman (1993), which demonstrated that investing in stocks with strong recent performance can yield additional returns. Later, Carhart (1997) added the momentum factor to well-known multi-factor models, making it a cornerstone in explaining market behavior and portfolio construction.
How to Calculate the Momentum Indicator and Its Technical Tools
The momentum indicator is typically calculated by comparing a stock's current price to its price at a set period in the past (e.g., 3, 6, or 12 months). The traditional formula is: Momentum Indicator = (Today's Price - Previous Period Price) / Previous Period Price × 100%. A positive value indicates upward momentum, while a negative value signals downward momentum. Technical indicators such as the Relative Strength Index (RSI), moving averages, MACD, and ADX are used to detect and assess momentum strength. In the Saudi market, technical analysts rely on these tools to identify short- and medium-term trading opportunities.
Momentum in the Saudi Stock Market: Reality and Examples
The Saudi stock market experienced strong momentum waves during 2024-2025, especially in the energy, mining, and petrochemical sectors, supported by rising oil prices and an improved economic environment. Tadawul data showed that the main market index (TASI) achieved annual gains exceeding 10% as liquidity momentum increased in blue-chip stocks such as Aramco, Ma'aden, and SABIC. Repeated momentum surges were also observed in the telecommunications sector, driven by strong earnings and investments in digital transformation.
Factors Influencing Momentum: Liquidity, Investor Sentiment, and Foreign Flows
Momentum is influenced by several factors, most notably liquidity inflows, investor sentiment, and global economic events. With Saudi Arabia opening its market to foreign investors, blue-chip stocks have become more sensitive to foreign capital movements, intensifying momentum waves, especially during earnings announcements or geopolitical events affecting oil prices. At the same time, local news such as major project launches or regulatory changes can trigger short-term momentum waves.
Momentum and Leading Sectors: Examples from Energy, Mining, and Telecommunications
Momentum has been particularly evident in the energy, petrochemical, and mining sectors, where companies like Aramco, Ma'aden, and SABIC posted notable gains in 2024. Ma'aden shares rose by nearly 30% in the first half of 2024, supported by global demand for minerals. In telecommunications, Saudi Telecom Company (STC) and Zain experienced successive upward momentum waves as digital services expanded. Momentum in these sectors is often linked to improved macroeconomic indicators or quarterly earnings results.
ETFs and Momentum: The Role of Institutional Liquidity
With the growing popularity of exchange-traded funds (ETFs) in the Saudi market, momentum has become a key driver of ETF price movements. Funds linked to high-performing sectors attract significant investment inflows, fueling momentum waves in their constituent stocks. For example, the Alkhabeer Diversified Income Traded Fund 2030 saw elevated trading activity amid clear buying momentum in the first half of 2024, positively impacting market liquidity and overall momentum levels.
Momentum and Trading Strategies: Risk and Benefit Analysis
Momentum strategies involve chasing stocks or assets that have recently shown strong performance, expecting the trend to continue. Advantages include the potential for high returns in active markets and portfolio diversification by gaining exposure to fast-moving stocks. However, momentum strategies carry high risks, such as sudden trend reversals and increased costs due to higher trading frequency. In the Saudi market, monitoring news and shifts in investor sentiment is crucial, as negative events can quickly erode momentum.
Momentum Versus Other Strategies: Value and Volatility
Momentum differs from value strategies, which focus on buying stocks priced low relative to their assets, and from volatility strategies, which target stocks with high or low price swings. Momentum often works in opposition to value investing, as top-performing stocks attract traders' attention while cheap or less active stocks are overlooked. In contrast, volatility strategies exploit rapid price changes but do not necessarily require trend continuation as momentum does.
Behavioral and Psychological Factors Behind the Momentum Phenomenon
Behavioral and psychological factors play a significant role in the emergence and persistence of momentum waves. Investors often follow prevailing trends driven by fear of missing out (FOMO) or the desire for quick gains. In Saudi Arabia, this phenomenon intensifies during positive market seasons or after strong earnings announcements. Additionally, rumors or unconfirmed news can prompt investors to make quick decisions, amplifying momentum waves, highlighting the importance of objective analysis and avoiding herd mentality.
Impact of Regulatory and Technological Interventions on Momentum
The Capital Market Authority seeks to regulate momentum's impact through policies such as margin protection and higher collateral requirements, aiming to maintain market stability and curb excessive speculation. Technological advancements, such as AI-powered trading platforms, have enabled investors to detect momentum signals faster and more accurately. These tools are expected to continue enhancing momentum detection capabilities, but also require awareness of the risks of over-reliance on automated signals.
Momentum Models in Financial Analysis: The Carhart Factor and Its Applications
The momentum factor is a core component of the Carhart four-factor model, used in portfolio analysis. This factor measures the return gap between top-performing and underperforming stocks, providing a scientific framework for assessing momentum's impact on historical returns. In the Saudi market, studies have shown that momentum-based portfolios sometimes outperform the general index, though with greater volatility that requires effective risk management.
Practical Examples of High-Momentum Stocks in the Saudi Market
Notable examples of stocks that exhibited strong momentum during 2024-2025 include Ma'aden, whose shares rose by about 30% in the first half of 2024, supported by higher metals prices. Saudi Telecom Company (STC) also posted significant gains driven by robust earnings and digital service expansion. SABIC benefited from recovering global demand for petrochemicals, boosting its upward momentum over consecutive periods.
Challenges of Applying Momentum in the Saudi Market
Despite the widespread adoption of momentum, its application in the Saudi market faces challenges such as liquidity fluctuations, rapid trend reversals, and the impact of sudden events on investor sentiment. Higher trading fees compared to some global markets may also reduce the effectiveness of short-term momentum strategies. Therefore, it is advisable to monitor technical indicators, diversify information sources, and avoid relying solely on momentum for decision-making.
Integrating Momentum with Other Investment Strategies
Many investors combine momentum with growth or hedging strategies to balance return and risk. For example, high-growth stocks with positive momentum can be selected, or derivatives used for hedging against trend reversals. Investment funds also allocate weights between momentum and value stocks, helping to achieve stable long-term returns.
Conclusion
Momentum plays a fundamental role in the movement of the Saudi stock market, especially as liquidity grows and investment tools advance. Practical experience shows that momentum strategies can deliver additional returns in favorable market conditions, but they remain exposed to price volatility and rapid trend reversals. It is important for investors and traders in the Saudi market to use momentum as an auxiliary tool within a comprehensive analysis framework that combines technical and fundamental analysis with monitoring of local and global market developments. Platforms like SIGMIX offer advanced analytical tools for monitoring momentum indicators and identifying trading opportunities, but they do not replace the need to consult a licensed financial advisor to assess risks and make appropriate investment decisions. In a changing market environment, awareness and discipline remain key to benefiting from momentum without taking on excessive risk.
