For this assignment below, can you please help me find a federal case and statutory law since the issues are SEC (federal) issues for the following question below:

Aquaman is president of a marine research company called "Underwater Leagues, Inc." On April 1, the research director of Underwater Leagues tells Aquaman that they've come up with "Oxygum," a means of breathing underwater by chewing a special kind of gum. Aquaman knows a great product when he hears it.

He delays announcing the invention to the public so that he can buy all the stock he can get his hands on. He buys 50,000 shares of Underwater Leagues, at $10 a share. After the announcement, the share price skyrockets to $50 per share.

a) If the shareholders bring a derivative action against Aquaman, what federal law should they accuse Aquaman of having violated (i.e., which federal statute)?
