High Quality Content by WIKIPEDIA articles! A Tobashi scheme is a financial fraud where a client's losses are hidden by an investment firm by shifting them between the portfolios of other (genuine or fake) clients. Any real client with portfolio losses can therefore have their accounts flattered by this process. This cycling cannot continue indefinitely and so the investment firm itself ends up picking up the cost. As it is ultimately expensive there must be a strong incentive for the investment firm to pursue this activity on behalf of their clients.
