INTRODUCTION Trading and gambling appear to share some similarities. Indeed, traders can get professionally involved in high-risk types of trading as if it were gambling. This research explores whether excessive trading can be conceptualized as a subset of gambling disorders. OBJECTIVE To better acknowledge the existence of an addictive-like trading behavior and to discuss its phenomenological similarities with gambling disorders. METHODS The data of 8 excessive traders out of a cohort of 221 outpatients seeking treatment in our Problem Gambling unit were analyzed. RESULTS Our case series revealed important similarities with gambling disorders in terms of diagnosis, trajectory and comorbidities. Like many disordered gamblers, excessive traders of this study experienced a number of small early wins, chased their losses, and ended up losing control over the money they invested. All of them invested in very risky stocks associated with short-term trading leading to potential large gains, but also with very significant losses. The structure itself of the two activities (gambling and trading) is very close. CONCLUSION Our results tended to support the idea of an addictive-like trading behavior as a subset of gambling disorders. Investing is not a form of gambling, but some people gamble with investments. Several observations and recommendations can be made: (i) conduct researches; (ii) build and validate specific assessment tools; (iii) develop strategies for prevention and treatment; and (iv) conduct more rigorous studies to clarify what we named an addictive-like trading behavior.
