A financial investigator is an actuary who investigates fraud and other types of financial crime, such as embezzlement, Ponzi schemes, money counterfeiting, and insider trading. They are sworn criminal investigators, and their job involves investigating white-collar crime. As a financial investigator, your duties include analyzing data, performing research on financial balance sheets and other financial reports, and looking into any discrepancies. You must be very familiar with accounting practices and legal investigation. Many financial investigators gain skills and experience while working in the insurance or actuarial fields before finding a job as an investigator.
