Back in 2009, Thomas Ammann found out through his investment banking job that Canon Inc would be acquiring a Netherlands-based company called Océ N.V. Being in a bit of a tight spot with his finances and seeing an opportunity to score some cash but wanting to avoid the prison time that could come with, he decided to be smart about things and put some distance between the tips and his profits, by employing a couple middlemen. In this case, those middlemen were his two girlfriends, Christina Weckwerth and Jessica Mang, who 1) put up the cash and 2) traded on the material non-public information. And while they probably would have taken issue with Ammann dating and tipping both of them, and would have perhaps been branded a lowlife by their friends and families, Tommy-boy made sure to keep the women a secret from one another, therefore only incurring the wrath of Mang's roommate on account of the insider trading business. Which, to be honest, Mang thought she was kind of being an uptight bitch about.

Mang bought OCE shares and then sold them five days later for almost twice what she invested, Pinto said. She wrote in her personal diary that Ammann advised her to invest, according to the prosecutor. Mang had been living in central London with a friend who worked in hedge-fund sales for Goldman Sachs, Pinto said. When told about Mang’s plans to invest in OCE, her friend “expressed her disapproval and kept calling it insider dealing.” In her diary, Mang wrote of her annoyance that her roommate insisted the trades were insider dealing. “Really?” Mang wrote, according to court documents. “Is that necessary? Increasingly prissy.”

Woman Who Insider Traded On (Two-Timing) Boyfriend's Behalf Did So In The Hopes Of Taking Relationship To The Next Level

In the summer of 2009, Jessica Mang, far left, met an investment banker named Thomas Ammann at a nightclub in London. Both liked what they saw and started seeing each other "at least once a week," on days he wasn't with his other girlfriend, Christina Weckwerth. Things were going well, but by November, Mang wanted more. So when Ammann said he was going to take her on a romantic getaway to Seychelles, and all she had to do first was use her own money to trade on material non-public information he'd obtained from his job at Mizuho International about Canon’s purchase of OCE NV, she jumped at the chance. Not only did he want to go away with her (huge!) but he was entrusting her with such an important project (huger!); Mang had read all the dating books and knew that when a guy asks you to violate securities laws, it meant things were getting serious. “He basically said that I show him that I trust him -- I invest the money, he still hadn’t specified how -- once that’s done, we’ll go on holiday in the Seychelles,” Mang said today at a London criminal court. “I thought that was a massive leap in commitment.” She said Ammann told her if she didn’t do it, “he didn’t want to be with me anymore.” “I thought, you know, this is a relationship that’s going to go somewhere, I definitely thought we were exclusive as well,” Mang said. “It wasn’t just sleeping together, in my mind we were definitely boyfriend-girlfriend from the start.” Ammann suggested that she should invest so they could build a future together, which she said she thought was a “very sweet and considerate thing he was doing.” Things that are unanswered at time but presumably be cleared up by the time the trial concludes: 1) When Ammann asked Weckworth to insider trade on his behalf (in April 2009), did he dangle a vacation in her face, too? Did she agree to the deal because she also thought it was indication wedding bells weren't far off, or was she just in it for the financial gain? 2) UNDER WHAT CIRCUMSTANCES* COULD THIS MISUNDERSTANDING POSSIBLY OCCUR: Mang said she didn’t know what due diligence was and “thought it was just a cute nickname he had for me.” If you have any ideas, we're all ears.
