In December 2016 the SEC charged Naris Chamroonrat and Adam L. Plumer in New Jersey over Nonko Trading, a phony day-trading firm that allegedly took more than $1.4 million from investors. Both consented to final judgments in 2017 (Chamroonrat in September, Plumer in November) with disgorgement but no penalty, and the Commission barred each from the securities industry. Chamroonrat pleaded guilty in a parallel criminal case.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

The complaint, filed December 21, 2016, alleges orders were never routed to markets, deposits paid the defendants' expenses and associates, and some money went to customers who asked to close accounts. Prosecutors announced parallel criminal charges. The repayments to departing customers are incidental to a fake-brokerage fraud, so the ponzi-schemes tag the record carried has been removed.

Outcome. Both defendants consented to final judgments in the New Jersey federal court, without admitting or denying the allegations. The court's judgment against Chamroonrat, filed September 18, 2017, enjoins him from antifraud and broker-registration violations and holds him liable for $918,147.31 in disgorgement and $71,549.24 in prejudgment interest; those amounts are deemed satisfied dollar-for-dollar by any criminal restitution, and no civil penalty was imposed. The judgment against Plumer, filed November 21, 2017, holds him liable for $67,468.38 in disgorgement, waives all but $15,500 of it because of his sworn financial condition, and imposes no penalty. The stored totals add the two disgorgement figures and show Chamroonrat's interest.

Two Commission orders then barred them. The March 8, 2017 order against Plumer and the September 26, 2017 order against Chamroonrat bar each from the securities industry and from penny stock offerings, and say Chamroonrat pleaded guilty on May 11, 2017 to a conspiracy count in a parallel New Jersey criminal case. The Plumer order refers to an earlier consent judgment dated January 23, 2017; the filed final judgment we read is dated November 21, 2017, and we did not resolve the difference.

What the sources do not show: Chamroonrat's criminal sentence, how much was paid, and any outcome for Avnon, Armon and G Six Trading, who were added to the same civil case in May 2017 and appear in a separate record.
