Saudi Stock Market Whales: Who Are the Major Players and Their Impact on the

The term 'Saudi stock market whales' refers to major investors or financial institutions with significant power to influence stock prices and indices. These players may include sovereign wealth funds like the Public Investment Fund (PIF), large investment companies, or even foreign investors holding substantial stakes in listed companies. In practice, their strength lies in their ability to move prices up or down by executing large transactions or reallocating their investment portfolios. Individual investors and smaller institutions often track their movements to gauge market direction, as whale activity can lead to rapid price increases or drops, especially in highly liquid or large-cap companies.

The primary mechanism of influence for whales is the volume of liquidity at their disposal and their ability to execute large trades that affect supply and demand dynamics. When they purchase large quantities of a particular stock, supply decreases and demand increases, driving the price up. Conversely, large-scale selling can exert swift downward pressure on prices. This effect is most evident in major companies such as Aramco, SABIC, and Al Rajhi Bank, where a single large transaction can alter the stock's trajectory within a trading session. Some whales also employ hedging strategies and periodic portfolio rebalancing to navigate market volatility, which in turn impacts individual investor sentiment and can trigger collective buying or selling waves.

Sovereign wealth funds such as the Public Investment Fund (PIF) are among the largest whales in the Saudi stock market. The PIF holds strategic stakes in pivotal companies like Aramco, SABIC, and major banks, in addition to investments in healthcare, technology, and renewable energy sectors. Major local and international banks and investment institutions also play a similar role, controlling significant liquidity and influencing the trajectory of key sectors. Furthermore, foreign ownership has increased in recent years, reaching around 7-9% of the total market by the end of 2024, adding new players to the whale category, especially after the Saudi market's inclusion in global emerging market indices.

Opposite to the Saudi stock market whales are the so-called 'small fish' or individual investors, who lack the power to significantly influence the market. These individuals are often affected by whale movements, as whale transactions can cause rapid price changes that small investors may not be able to keep up with or hedge against. However, logically analyzing and tracking whale activity can help individual investors make decisions based on real market data, rather than rumors or random speculation.

The influence of Saudi stock market whales is typically concentrated in sectors that carry the most weight in the main market index (TASI), such as the energy sector (Aramco, SABIC), banking (Al Rajhi Bank, Al Ahli), and telecommunications (STC). Combined, these sectors represent about 60-70% of the market capitalization, meaning any significant movement within them directly affects overall market performance. Recently, there has been growing interest in other sectors such as mining, renewable energy, and healthcare, with new local and foreign investment funds focusing on economic diversification in line with Vision 2030.

The strength of market whales depends on the size of the companies they invest in. Major companies like Aramco, SABIC, Al Rajhi Bank, and STC boast large market capitalizations and high dividend yields. For example, Aramco's share price is around SAR 33-35 in 2025, with a market value exceeding SAR 2.5 trillion and an annual dividend yield between 8-9%. SABIC's share price is SAR 110-120, with a price-to-earnings ratio of 15-17, and annual dividends of 5-7%. These indicators demonstrate financial stability and the strong appeal these companies hold for whales, who prefer investing in firms with robust financial records and consistent dividends.

Recent years have seen a rise in foreign ownership in the Saudi stock market, especially after the foreign ownership cap was raised and the market was included in indices such as MSCI and FTSE. Foreign ownership is estimated at about 7-9% of the total market by the end of 2024, with a focus on major companies and leading indices. The entry of foreign capital at this scale enhances market dynamics and increases traded liquidity, but also adds complexity during global volatility, as these investors may quickly shift their portfolios, impacting overall market performance.

The Saudi economy is closely tied to global oil prices, so any change in crude prices directly affects the performance of major stocks and whale behavior. Rising oil prices boost the profits of energy companies like Aramco and SABIC, increasing their investment appeal. Conversely, sharp declines in oil prices put pressure on profits and reduce available investment liquidity. Global monetary policies, such as changes in US interest rates, also play a key role in the decisions of major investors and their movements between stocks, bonds, or hedging against volatility.

The Saudi stock market is strictly regulated by the Capital Market Authority (CMA), which aims to protect investors and ensure fair and transparent trading. The CMA has implemented systems to disclose large transactions and major investor holdings, along with strict financial disclosure standards for listed companies. Procedures for listing small and medium-sized companies have been simplified, margin lending has been expanded, and advanced technologies have been adopted to monitor trading and detect any attempts at manipulation or insider trading.

Individual investors in the Saudi market face significant challenges due to whale dominance, as their sudden movements can create sharp, unpredictable volatility. Nevertheless, opportunities exist by monitoring whale activity and analyzing the financial data of leading companies. It is often recommended to diversify across sectors and avoid following rapid speculation waves, in addition to using risk management tools such as stop-loss orders and keeping up with economic news and quarterly reports. Financial education and utilizing analysis materials from platforms like SIGMIX can make a difference in understanding market dynamics.

The Saudi stock market witnessed a wave of IPOs and new listings of major companies in 2024-2025, such as the Saudi Airlines offering and real estate and tourism investment funds. Leading companies posted strong quarterly results, and average monthly trading volume rose to around 2-3 billion shares. Investments expanded in technology and renewable energy, with artificial intelligence solutions applied to market monitoring and analysis. All these developments have boosted the confidence of local and foreign investors, contributing to market stability and increasing its appeal to large-scale capital.

To monitor whale movements, many investors track official announcements regarding major holdings, analyze the size of daily large transactions, and study quarterly financial reports from leading companies. Analytical platforms like SIGMIX provide advanced tools for chart analysis, liquidity flows, and technical indicators, helping to identify market trends that may reflect whale activity. It is essential to rely on official and trustworthy sources and avoid following rumors or unverified recommendations.

One of the key lessons individual investors can learn from observing whale movements is the importance of hedging and portfolio diversification. Instead of trying to follow whale trades or join speculative waves, it is preferable to focus on companies with strong financial fundamentals and spread risk across different sectors. Setting stop-loss orders and continuously monitoring economic news can also help reduce the impact of sharp volatility. Ongoing education and leveraging advanced analytical tools can empower individual investors to better face the challenges posed by whale movements.
