  • 40-year-old Katherine Larsen does not go back to trolling Citadel Securities and Ken Griffin.
  • She has purchased banner banners and mobile truck ads to “spread awareness,” the Institutional Investor reported.
  • Larsen has quadrupled its AMC investment to more than half a million dollars since January, II reported.

A retailer is not giving up on its trolling campaign against Citadel Securities and its founder, Ken Griffin.

The trader, 40-year-old Katherine Larsen from Oceanside, California, has bought mobile truck ads, flyers and Times Square digital billboards in an attempt to raise the bar for retailers who feel hurt when Robinhood stopped trading meme shares like GameStop and AMC, according to a profile from Institutional Investor.

An ad read “Do you think #Ken Griffin lied?” and another read “#Citadelisnotretail,” the report said. On Monday, she tweeted a picture of one airplane banner reading “#stillherekenny wewantfairmarkets.org.”

The report said Larsen, a bartender at The Kraken bar in Cardiff, California, invested in the cinema chain AMC in January and has since quadrupled his investment to $ 520,000. On Twitter, she is known as @ katstryker111, and her background image shows a monkey with green laser eyes – a well-known icon among the retailers.

Although her investment has been profitable, she has questioned Wall Street practices, such as pay-for-order flow, said the institutional investor profile that quoted Larsen as saying she would not “step back” and wish to continue to “spread consciousness.” In a Twitter message, Larsen confirmed to Insider the report according to the institutional investor.

Insider reported in September that a class action lawsuit alleged by market maker Citadel Securities was conspiring with Robinhood to push the price of meme stocks like GameStop and AMC down on January 28 when the purchase was stopped on the trading app.

Citadel Securities has fired back at retailers on Twitter, saying they were spreading “internet conspiracies” and an “absurd story”. Ken Griffin said last week that the theories were like a bad SNL joke. Citadel Securities declined to comment on the story.

A 45-page report from the US Securities and Exchange Commission refuted some of the theories about the January episode. Among other results, it said Citadel Securities and others did not snatch GameStop shares to hedge against call options they wrote, Axios reported.
