    Unauthorized options trading and concealed losses

    The SEC alleged that Bing Sung exceeded trading limits in an AT&T-related options program, made large unauthorized technology-stock bets, and provided inaccurate performance reports that understated losses. RhumbLine agreed to censure, improved controls, and a $50,000 penalty; Nelson separately accepted a fine and suspension. Sung later agreed to a fine and an industry bar.
