Mark Cuban is a badass businessman with a net worth of over $2.5 billion and owns the Dallas Mavericks. He has also been cleared of insider trading charges alleging he sold his take in a Canadian Internet company nine years ago to avoid a $750,000 loss. Cuban reportedly spent much more than that on his defense in this case alone. A Jury of two men and seven women found that the information Cuban traded on wasn’t confidential and that he had not promised not to trade on it. Cuban prides himself on knowing when to pursue a good investment and when to walk away. This was a low-stakes case that turned into a high profile loss for the SEC. Learn from Mark, sometimes you just have to walk away.
