Manuel P. Asensio (born 1954) is a money manager in New York best known for his work as an activist short-seller. Since 2000, Asensio and his firm have been subject to regulatory sanctions by the Financial Industry Regulatory Authority (FINRA).
He is also the author of a book about his work entitled Sold Short: Uncovering Deception in the Markets.
Asensio earned a Bachelors of Science in Economics degree from the University of Pennsylvania’s Wharton School and attended Harvard Business School where he was the roommate of John Paulson. He traded while a student at Harvard Business School, and established Boca Raton Investment Corp. as his own trading firm when he graduated in 1982. He went to work for Bear Stearns in 1986.
As an activist short seller, Asensio sold short companies he believed to be engaging in fraud, and was noted for publicizing his negative opinions. He made claims of fraud or misrepresentation involving 26 companies as of 2004. According to Asensio, of the 26 companies he publicly campaigned against, the average decline in value was around 86 percent, wiping out $30 billion dollars in market value, from which he grossed millions in profits.
Prior to making a short sale, Asensio would look at statements made by the company, to determine if they are flawed, and if claims made by the company can be verified. Asensio said in a 2004 magazine interview that "If there's a big variance between that and with what the company is saying, which we know is not right, it is reflected in the stock price that attracts us to a market. If you do identify a security that's trading significantly above its fundamental value and if there are a set of representations made by a company which you find to be faulty, and that those representations impact the stock price, you will make money. If you have the sophistication to be able to trade, you will be able to make a substantial amount of money."
As of 2004, of the 26 companies he shorted and campaigned against, eleven were delisted from stock exchange trading or went bankrupt or otherwise failed, according to Asensio.
His short selling activities and public statements resulted in numerous lawsuits. Asensio said that he had been sued for $1 billion in seven states as of 2004, and spent around $10 million defending himself, but had yet to lose a monetary judgment. One jury had found him guilty of misrepresentation without ordering a judgement. That resulted in the former National Assn. of Securities Dealers, now FINRA, imposing a fine and disbanding his broker-dealer operation.
In November 2000, the NASD (now FINRA) sanctioned Asensio & Company Inc. and Manuel Asensio, for Short Selling, Trade Reporting, and Internet Advertising Violations.
In July 2006, the National Adjudicatory Council of the NASD upheld a hearing panel's ruling that barred Asensio "from association with any NASD member in any capacity" and fined him $20,000. The NASD barred Asensio and his firm for failing to respond to requests for information. It found that Asensio made statements in research reports that criticized PolyMedica Corp. that were "misleading," by stating incorrectly that he was shorting the company when he was not, and by making similar disclosure rule violations. Asensio denied wrongdoing. All appeals were denied.
In August 2007, Asensio Brokerage Services, Inc. nka Integral Securities, Inc. was expelled by FINRA for failure to pay fines and/or costs.
