PARIS, FRANCE – May 27, 2026 – Elie Houri, a French national, has been fined €20,000 by the Autorité des marchés financiers (AMF) Enforcement Committee for insider dealing. The decision, rendered on May 20, 2026, marks a significant enforcement action by the French financial regulator against individuals exploiting privileged information for personal gain in the markets.
The AMF’s ruling against Houri stems from his involvement in a scheme that leveraged confidential information regarding the takeover of Artefact, a listed digital marketing and data exploitation firm. This conviction underscores the AMF’s ongoing vigilance in maintaining market integrity and ensuring fair trading practices.
The Charges Against Elie Houri
Elie Houri was found to have committed insider dealing by acting on a recommendation from his cousin, Ytane Mamou, which was based on non-public, privileged information. The core of the accusation is that Houri acquired shares in Artefact in July 2021, just days before the public announcement of its takeover, leading to an immediate surge in the stock price. The AMF determined that the information concerning the takeover was inside information as early as June 10, 2021, when the sale process was already well-advanced.
Mamou, possessing this crucial information, acquired Artefact shares for himself and his family members before recommending the investment to Houri. Houri then proceeded to invest over €40,000 to acquire more than 7,000 Artefact shares on July 16, 2021. This timing, just ten days prior to the official announcement on July 26, 2021, was deemed highly suspicious and a direct violation of market regulations.
Scale of the Crime
While the direct monetary amount “stolen” is not a traditional theft, the scheme involved Elie Houri investing over €40,000 based on illicitly obtained information. Insider dealing distorts market fairness, creating an uneven playing field for other investors. The AMF imposed a fine of €20,000 on Elie Houri, alongside a €30,000 fine for his cousin, Ytane Mamou, totaling €50,000 in sanctions from the regulator. The victims, in this context, are not specific individuals or entities but rather the integrity and fairness of the broader financial market and all investors who traded Artefact shares without access to the same privileged information.
“Insider dealing fundamentally undermines investor confidence and the principle of equal access to information in our financial markets. The AMF’s decision sends a clear message that such abuses will be met with firm regulatory action.”
The immediate impact of the takeover announcement was a jump of over 34% in Artefact’s stock price in a single trading session, highlighting the significant advantage gained by those privy to the inside information.
Who Is Elie Houri?
Elie Houri is identified as a French national and the cousin of Ytane Mamou, who was also implicated and fined in the same insider dealing case. Public information regarding Houri’s age, specific profession, or company affiliations is not available. His involvement in this case appears to be primarily driven by the recommendation from his relative, leading to his acquisition of Artefact shares based on inside information.
Investigation Details
The investigation into the Artefact share transactions was conducted by the Autorité des marchés financiers (AMF), France’s financial market regulator. The probe spanned several years, meticulously analyzing trading patterns during the summer of 2021. The fraud was uncovered through a combination of factors, including the identification of plausible channels for the transmission of inside information, particularly the familial link between Elie Houri and Ytane Mamou. Investigators also noted the highly atypical nature and timing of the disputed transactions, given the limited prior stock market experience of both individuals.
Crucially, neither Mamou nor Houri provided convincing explanations for their sudden and significant investments in Artefact shares just before the takeover announcement. Houri himself reportedly admitted to investing primarily on his cousin’s advice, reinforcing the AMF’s findings. This thorough investigation by the AMF ultimately led to the formal charges and subsequent conviction for insider dealing.

What Happens Next
Elie Houri has been convicted and fined €20,000 by the AMF Enforcement Committee. While no asset freezes have been mentioned, it is important to note that an appeal may be lodged against this decision. The appeals process could potentially lead to a re-evaluation of the case or a modification of the sanction, though the AMF’s initial ruling stands as a strong precedent.
Protecting Yourself
This case serves as a critical reminder of the pervasive threat of insider dealing to market integrity. Investors should be acutely aware of several red flags that can indicate illicit activity. These include highly atypical transactions, especially by individuals with limited prior trading experience, and purchases timed suspiciously close to major corporate announcements. Unsolicited investment recommendations, particularly those hinting at privileged information, should always be viewed with extreme caution. Always question the source and veracity of investment advice, especially if it promises unusual returns or suggests acting on non-public information. Rely on credible, publicly available information and regulated financial advisors. The AMF’s vigilance, as demonstrated in the Elie Houri case, is crucial, but individual investor awareness remains the first line of defense against market manipulation.
