Mark Cuban has never run a hedge fund, but what if he had when the SEC came after him last year for purportedly trading on insider information in the small-cap stock Mamma.com? If he'd had a hedge fund at the time, it likely would have also had to be wound down when details of his arrest first emerged. The SEC later dropped the charges, although it recently made some noise about bringing them back. Wrong-doing deserves to be regulated and prosecuted by the SEC. The government should devote more resources to enforcement with the best qualified people involved. A few correct convictions will have a ripple effect throughout the hedge fund industry and discourage illicit behavior. However, the SEC needs to realize it is playing with people's lives and livelihoods here. Investors will -- understandably -- redeem first and ask questions later when the agency launches actions against a fund or fund manager. They have a responsibility to do their jobs to the best of their abilities, as do hedge fund managers and senior executives within public companies.
