Mizuho International

Remember Thomas Ammann (pictured at right)? For those who need a refresher, he was an investment banker who met a woman (Jessica Mang, center) at a London nightclub in 2009, started seeing her “at least once a week,” on days he wasn’t with his other girlfriend (Christina Weckworth, left), and then, when Mang asked to crank things up a notch on the relationship in the form of a romantic getaway, told her he’d take her to Seychelles on the condition she’d first 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 and then give him half the profits. Mang naturally jumped at the chance to take things to the next level (“I thought [him entrusting me with such an important task] was a massive leap in commitment…I thought, you know, this is a relationship that’s going to go somewhere,” she later told a London criminal court), as did Weckworth when she was asked to do the same, but not in exchange for a free holiday. Anyway, Ammann ended up pleading guilty to “insider trading and encouraging the women to commit insider trading” last year and today was sentenced to 32 months in prison and a fine of 94,568 pounds ($151,820). (The women themselves were somehow found not guilty.) But the most delightful part of this story, reported by Bloomberg this morning? Read more »

Jessica Mang, who traded material non-public information based on tips obtained by her Mizuho investment banker boyfriend, Thomas Ammann, because he promised to take her on vacation afterward and also because she thought his entrusting her with such a high level task was a sign he wanted to get serious, was cleared by a jury today, as was Christina Weckwerth, Thomas Ammann’s other girlfriend/execution trader.

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 and then give him half the profits, 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 if a guy asked you to violate securities laws, it meant things were getting serious.
