OMIS, Croatia (AP) – A Croatian woman suspected in the United States of using insider information to gain millions on the Adidas-Reebok deal said she has never bought any stock and has no clue about how the stock exchange functions.

Croatian media suggested Monday that 63-year-old Sonja Anticevic, a retired tailor who sometimes works as a cleaning lady to supplement her monthly pension of 1,600 kuna ($263), could be a victim of stolen identity.

Briefly appearing at the doorstep of her apartment in a working-class suburb of the southern city of Omis on Sunday, Anticevic, wearing a plain, sleeveless black cotton dress, told The Associated Press she “never bought a stock and I have no idea how that works.”

“Leave me alone, please. I’m in shock,” she said before closing the doors. She refused to comment further.

Jutarnji list daily reported Monday that Anticevic’s 25-year-old nephew is a broker in New York and that Anticevic keeps contact with him. It was unclear whether the nephew played any role in the trading and if he did, if he did so with Anticevic’s approval.

The U.S. Securities and Exchange Commission said Friday it froze Anticevic’s accounts, saying she netted $2 million in well-timed trades of Reebok International Ltd.

The SEC said Anticevic allegedly purchased $130,000 worth of call contacts – options to purchase Reebok stock at set price. When shares of Canton, Mass.-based Reebok rose after its $3.8 billion acquisition by Adidas-Salomon AG was announced last Wednesday, Anticevic exercised the options, buying Reebok shares at the lower price, then reselling them at the higher market price for a profit of $2 million.

The SEC said the timing was enough to raise suspicions and led to the freezing of Anticevic’s assets while the SEC investigates further.

Croatian police said Monday they haven’t received any request from the U.S. regarding the case.

The reports immediately made Anticevic a front-page topic in Croatian media, which puzzled over how she possibly could have struck such a deal. There also were speculations that Anticevic’s name and account, with or without her knowledge, were used for someone else’s trading.

Anticevic’s neighbors in Omis, a city of 15,500 residents, said she retired a few years ago after working all her life in a local underwear factory. She lives with her husband and daughter, who works in a kindergarten, in a two-room apartment provided by the factory.

The family has no computer and lives a moderate life, neighbors said, adding they doubted she would have $130,000 to buy Reebok shares to start with.

Local media said Anticevic’s identity also could have been used by someone unknown to her, as electronic trading identification could be forged.

Miljenko Ficor, head of the Croatian Securities Commission, said such deals are always checked. But, he said, “I wish that in the end, it turns out our countrywoman was just lucky, trading the stocks accidentally at that time.”
