Scotts Valley Resident Pleads Guilty To Defrauding Investors In Medical Technology Company


A California man pleaded guilty yesterday in connection with a scheme to defraud investors in a publicly traded company’s securities and manipulate the company’s stock price.

According to court documents, Jason Nielsen, 48, of Scotts Valley, was a large shareholder of Arrayit, a publicly traded medical device company based in California. From approximately 2019 through April 2020, Nielsen engaged in an unlawful “scalping” and “spoofing” scheme to manipulate the price of Arrayit securities. Nielsen used online message boards to publicly post false and misleading information about the nature of his trading in Arrayit securities, in order to induce others to purchase Arrayit securities and thereby drive up the stock’s price, a practice known as “scalping.”
