“ To that end consider the strange story of Harry Markopolos. Mr. Markopolos is the former investment officer with Rampart Investment Management in Boston who, for nine years, tried to explain to the Securities and Exchange Commission that Bernard L. Madoff couldn’t be anything other than a fraud. Mr. Madoff’s investment performance, given his stated strategy, was not merely improbable but mathematically impossible. And so, Mr. Markopolos reasoned, Bernard Madoff must be doing something other than what he said he was doing. In his devastatingly persuasive 17-page letter to the S.E.C., Mr. Markopolos saw two possible scenarios. In the “Unlikely” scenario: Mr. Madoff, who acted as a broker as well as an investor, was “front-running” his brokerage customers. A customer might submit an order to Madoff Securities to buy shares in I.B.M. at a certain price, for example, and Madoff Securities instantly would buy I.B.M. shares for its own portfolio ahead of the customer order. If I.B.M.’s shares rose, Mr. Madoff kept them; if they fell he fobbed them off onto the poor customer. In the “Highly Likely” scenario, wrote Mr. Markopolos, “Madoff Securities is the world’s largest Ponzi Scheme.” Which, as we now know, it was. Harry Markopolos sent his report to the S.E.C. on Nov. 7, 2005 — more than three years before Mr. Madoff was finally exposed — but he had been trying to explain the fraud to them since 1999. He had no direct financial interest in exposing Mr. Madoff — he wasn’t an unhappy investor or a disgruntled employee. There was no way to short shares in Madoff Securities, and so Mr. Markopolos could not have made money directly from Mr. Madoff’s failure. To judge from his letter, Harry Markopolos anticipated mainly downsides for himself: he declined to put his name on it for fear of what might happen to him and his family if anyone found out he had written it. And yet the S.E.C.’s cursory investigation of Mr. Madoff pronounced him free of fraud.
