KCG Holdings. is an American global financial services company.

According to the law firm press release, it is alleged that starting in January 2013, ten Argentinean nationals deposited millions of unregistered Biozoom shares in accounts they opened with two US brokerage firms, in preparation for a pump-and-dump scheme, according to a case filed by the Securities and Exchange Commission (“SEC”) against the alleged perpetrators.

Starting on May 16, 2013, the Argentinean nationals started selling the unregistered, fraudulent Biozoom shares into the marketplace. A week later, Biozoom began publishing press releases claiming it had created the world’s first handheld diagnosing device, which could instantly measure a number of “biomarkers” of the human body. The press releases were published in the national media. Advertisements were broadcasted on certain radio stations.

On June 25, 2013, the SEC suspended the Biozoom shares from trading. In early July, 2013, the SEC filed a lawsuit against the alleged Biozoom pump-and-dump perpetrators, charging them with fraud.

On September 15, 2014, the Court issued an Order appointing lead Plaintiff and approving the selection of lead Counsel. Lead Plaintiff filed an amended Complaint three days later.

A third amended Complaint was filed by the Plaintiffs on April 29, 2015.

On August 20, 2015, the Court issued an Order granting Defendants' motion for summary judgment and closing this case.
