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 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.

“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.”

She wrote in her diary that Ammann advised her to invest. Mang bought OCE shares and then sold them five days later for almost twice what she invested, the FSA said. “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.”

Update 11/15/12: Questions that remain unanswered at this time:

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* this misunderstanding could 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.

  2. Competitive Quant says:

    Unrelated, but can we enter Matt in Cap IQs modeling competitiong? – http://www.modeloff.com/ ? It says the first round's already over but I'm sure there's some kind of waiver process.

  3. <3 Wedding Crashers says:

    "when a guy asks you to violate securities laws, it meant things were getting serious."

    I guess by this logic Matt must be a stage 5 clinger.

    She's cute, but not the brightest light in the chandelier

    I thought he said he wanted to "do dull asians" and assumed he was talking about me.

    “I thought, you know, this is a relationship that’s going to go somewhere"

    Ladies, if your man doesn't threaten to leave you if you don't insider trade for him it just means he doesn't love you.

  11. ROR says:

    Mang's minge must be dericiuos.

  12. Four Hour Urologist says:

    He had her thinking "dew diligence".

    Dear Diary,
    This stock market thing is easy. Tommy tells me what to buy, I double my money AND he invites me to Seychelles. Yay!

    • spinzone says:

      Most of the dickheads working on Wall Street don't "get" the stock market, so it's a little hypocritical to expect some Asian chiropractor to.

    Dear Jessica,

    That skinny latte isn't working.

  20. Guest says:

    Damn. If it came down to a choice between the two I am definitely banging out the chubby asian over the female who looks like a female cracked out version of Charlie Sheen.

  21. Guesteeculos says:

    Some questions:
    Will she claim that her implants made her temporarily insane? Or go with the traditional Chewbacca defense? And yes, DD stands for due diligence.
    Was Ammann a big Roy Orbison fan?

    Diary Entry for Ms. Lang the following day:

    "He must think I'm an idiot for not wanting to do "it"…what girl doesn't want to go the Seychelles?"

  23. Doubting Thomas says:

    I agree with Thomas. Nothing says "commitment" like violating security fraud together. And Anal.

    1. Invest money

  25. Guest says:

    There's an analyst in my office whose name one of the MDs doesn't know but similarly refers to him simply as "due diligence."

    Choot you? I'm not gonna choot you, Mang. Thomas, choot that piece of chit.

    Old news and the coverage back in the glorious UK was much funnier: http://www.telegraph.co.uk/news/uknews/crime/9625

    " Mang's flatmate Jean Wang said she raised concerns about the proposed investment in Oce. She said: "I think when she first mentioned it I was surprised that Thomas had suggested it. I basically said I do not think Thomas should be doing that, that's insider trading."

    Ms Wang, who works for Goldman Sachs, added: "The impression I got was that Thomas was using the information he had from working on the private deal and trying to benefit from that."

    • Jean Wang says:

      Hey! That's our job!

    • guest says:

      You're an idiot and:
      1) The above Bloomberg article/DB post is based on things that went on in court YESTERDAY (when the articles were written) i.e. no, not old
      2) The above bits from the Telegraph article, which is not funny in the slightest, were reported by DB a month ago.

  28. Mr. Fang says:

    Wait, Wang AND Mang? That IS funnier. Any Chang's?
