The provided source details the indictment of Vladimir Artamonov, a Harvard Business School graduate, for allegedly orchestrating a Ponzi scheme that defrauded investors, including former classmates, out of over $4 million. Artamonov is accused of falsely claiming he could predict Warren Buffett's Berkshire Hathaway stock selections, promising exorbitant returns of 500% or more with minimal risk. Instead of investing as promised in "Project Information Arbitrage," he allegedly used investor funds for risky short-term options unrelated to Berkshire Hathaway and repaid earlier investors with money from newer ones. This case serves as a stark warning against fraudulent investment strategies offering improbable gains, and authorities have clarified that neither Berkshire Hathaway nor Warren Buffett are implicated in any wrongdoing.
