This study presents the first comprehensive evidence of insider trading patterns and abnormal profits in the Turkish stock market using almost 65,000 insider transactions for the period of 2008–2019. Our findings show that insiders earn a significant 6.58% abnormal profit during the one year following insider trading. Officers, directors, and institutional investors earn even more. Both purchases and sales are profitable. Top executives, major shareholders, and institutional investors earn significant dollar profits. Additionally, uninformed investors can beat the market by mimicking the portfolios of insiders, while evidence shows that regulatory changes do not reduce insiders’ profits. Finally, this study provides important trading implications for investors and regulatory implications for policymakers everywhere.
