INSIDER TRADING AND MARKET MANIPULATION IN NIGERIAN CAPITAL MARKETS: IMPACT ON INVESTOR CONFIDENCE

CHAPTER ONE

INTRODUCTION

Abstract

This study examines insider trading and market manipulation in Nigeria’s capital markets and their detrimental effects on investor confidence. Through secondary analysis of SEC reports, NGX data, and academic literature from 2020 to 2025, the research highlights persistent challenges in enforcement, with few convictions despite regulatory frameworks like the Investments and Securities Act 2007 (as amended). Findings indicate that perceived insider dealing and manipulative practices contributed to volatility in the NGX AllShare Index and reduced foreign portfolio inflows by 2030% during highprofile suspicion periods. While market capitalization grew to ₦61.9 trillion by mid2025, investor surveys reflect lingering distrust, with confidence indices below 50%. The study recommends enhanced surveillance technology, stricter penalties, and public disclosure reforms to restore faith in market fairness.

1.1 Background of the Study

Nigeria’s capital markets, regulated primarily by the Securities and Exchange Commission (SEC) and the Nigerian Exchange Group (NGX), have grown significantly since the 2008 global financial crisis, with market capitalization reaching ₦61.9 trillion by mid-2025 amid economic reforms (PwC, 2025). However, insider trading, defined as trading on material non-public information, and market manipulation, such as pump-and-dump schemes or false rumors, remain endemic, undermining market integrity (Akinlabi, 2024; Olawoyin, 2023).

Insider trading erodes the principle of equal information access, allowing connected individuals, including directors, executives, or regulators, to profit unfairly, while manipulation distorts prices through coordinated buying or selling or spreading misinformation (Harvey, 2021). In Nigeria, the Investments and Securities Act 2007 prohibits these under Sections 111 to 115, yet enforcement is weak: no major convictions for insider trading occurred between 2020 and 2025, despite SEC investigations into suspicious trades around mergers and earnings announcements (Ogunmokun, 2024). Market manipulation cases, often involving rampers inflating penny stocks, led to occasional sanctions but rarely criminal prosecutions (Osuofa, 2025).

The NGX All-Share Index surged 31.81% in 2024, driven by banking and consumer goods sectors, but volatility from suspected manipulation, such as sharp spikes in low-cap stocks followed by crashes, deterred long-term investment (Madueke, 2025). Foreign portfolio investors, key to liquidity, reduced holdings amid perceptions of unfair play, with outflows of ₦500 billion in volatile periods (Sule et al., 2024). Domestic retail participation grew via apps, but surveys show 60% of investors cite insider dealing as a major concern, preferring fixed deposits over equities (Transparency International, 2024).

High-profile suspicions, like unusual trading before 2023 recapitalization announcements or 2024 dividend declarations, fueled narratives of elite capture, where politically connected traders exploit information leaks (Akinlabi, 2024). This breeds cynicism: investor confidence indices hovered at 40% to 45% in 2024 to 2025, below pre-2008 levels (PwC, 2025). The SEC’s 2025 revised rules on insider disclosures and surveillance upgrades aim to address this, but implementation lags (Olawoyin, 2023). In a market aspiring to emerging status, these abuses hinder capital formation, increase cost of equity for issuers, and perpetuate inequality between informed elites and ordinary investors (Harvey, 2021). The background thus reveals a paradox: robust growth masked by integrity deficits that threaten sustainable development of Nigeria’s capital markets.

1.2 Statement of the Problem

Insider trading and market manipulation persist as significant challenges in Nigeria’s capital markets, undermining price discovery mechanisms and diminishing investor trust despite established regulatory frameworks (Ogunmokun, 2024; Sule et al., 2024). Empirical evidence suggests abnormal trading volumes preceding material announcements impact approximately 15 to 20 percent of major stocks annually, resulting in artificial price volatility and substantial losses for retail market participants (Madueke, 2025). Structural weaknesses in enforcement, characterized by conviction rates below 10 percent, perpetuate a culture of impunity, with many high-profile cases remaining unresolved for extended periods (Akinlabi, 2024).

These conditions have cultivated widespread market distrust, with survey data indicating between 55 and 65 percent of investors perceive markets as favoring privileged insiders, consequently depressing participation rates and overall liquidity (Transparency International, 2024). The reputational consequences have been particularly detrimental to foreign capital inflows, which play a crucial role in market depth, with estimated outflows reaching 20 percent during periods of heightened volatility (PwC, 2025). Domestic investor confidence has eroded in parallel, manifesting in capital migration toward alternative asset classes such as real estate and cryptocurrencies, thereby reducing funding availability for listed corporations (Olawoyin, 2023). Failure to effectively address these systemic abuses threatens to perpetuate market stagnation and compromise broader economic diversification objectives.

1.3 Objectives of the Study

The main objective is to examine insider trading and market manipulation in Nigerian capital markets and their impact on investor confidence.

Specific objectives are:

1. To identify prevalent forms of insider trading and market manipulation in the NGX.
2. To assess how these practices affect market efficiency and investor participation.
3. To evaluate regulatory responses and recommend measures for enhanced confidence.

1.4 Research Questions

1. What are the common manifestations of insider trading and manipulation in Nigeria’s markets?
2. How do these practices influence price integrity and investor behavior?
3. What regulatory shortcomings exist, and how can they be addressed?

1.5 Significance of the Study

This study highlights integrity deficiencies within Nigeria’s capital markets, providing guidance for the SEC and NGX to enhance surveillance mechanisms and implement stricter penalties, thereby fostering investor confidence and capital inflows. It raises investor awareness of associated risks while supplying policymakers with empirical evidence to support regulatory reforms consistent with international standards. From an academic perspective, this research advances the literature on governance in emerging markets.

1.6 Scope and Limitations of the Study

The study examines insider trading and manipulation trends between 2020 and 2025, analyzing secondary data. Key limitations involve dependence on documented cases, which likely suffer from underreporting, as well as the lack of direct input from primary insiders.

1.7 Operational Definition of Terms

• Insider Trading: Trading securities using material non-public information.
• Market Manipulation: Artificial influencing of supply/demand to distort prices.
• Investor Confidence: Willingness to invest based on perceived market fairness.
• Nigerian Capital Markets: NGX-listed equities and related instruments.
• Regulatory Enforcement: SEC actions against violations.
