Abstract

This study analyzes deviations in the Initial Public Offering (IPO) process as the root of stock price manipulation among issuers in Indonesia for the 2020-2025 period. Using a qualitative approach with a multiple case study method, this research examines three issuers sanctioned by the Financial Services Authority (OJK): PT Berkah Beton Sadaya Tbk (BEBS), PT Repower Asia Indonesia Tbk (REAL), and PT Multi Makmur Lemindo Tbk (PIPA). Data were collected through in-depth interviews with 12 informants consisting of former OJK/Indonesia Stock Exchange (IDX) officials, capital market practitioners, academics, investigative journalists, and legal practitioners, as well as document analysis of prospectuses, financial statements, and OJK documents. The results identify four forms of IPO deviations: manipulation of material fact information, share allotment engineering, due diligence procedure violations, and discrepancies in the use of IPO funds. The BEBS case demonstrates how IPO deviations create structural conditions that facilitate pump-and-dump schemes through 57 nominee accounts, generating manipulative profits of IDR 14.5 trillion. This study identifies five factors causing weak detection and prevention: regulatory factors, law enforcement, corporate governance, market structure, and economic incentives. These findings confirm the OJK's statement that the root of stock price manipulation originates from deviations in the IPO process and emphasize the need for stronger supervision and enforcement.

Abstract

This research investigates how breaches of the prudential principle contribute to fraud within Indonesia’s capital market, focusing on listed entities penalized by the Financial Services Authority (OJK). Utilizing a qualitative multiple-case study approach, the analysis centers on four prominent cases: PT Repower Asia Indonesia Tbk (REAL), PT Multi Makmur Lemindo Tbk (PIPA), PT Bliss Properti Indonesia Tbk (POSA), and PT Mirae Asset Sekuritas Indonesia. Secondary data were gathered from OJK official statements, sanction rulings, national media reports, and legal documents spanning 2022–2025. Through pattern-matching and cross-case synthesis, three recurring violation patterns emerged: inadequate customer due diligence by underwriters, submission of inaccurate information during share subscription and allocation, and lapses in directors’ internal oversight. Fraudulent schemes primarily involved masking true beneficial ownership via nominee structures and offshore vehicles, alongside the fictitious recognition of assets financed by IPO proceeds. OJK’s enforcement strategy demonstrates a tiered, proportionate approach that extends to market intermediaries and, in select instances, crosses national borders. A notable systemic flaw identified is an enforcement delay of up to two years, which may weaken deterrence. The study validates the applicability of the fraud pentagon framework in emerging markets and offers actionable recommendations for enhancing risk-oriented supervision.
