Mark Cuban, the billionaire owner of popular US basketball team Dallas Mavericks, is financing a new Web site that will investigate stock fraud and corporate wrongdoing, an Associated Press report said.
Cuban said he had not been a direct victim of fraud but was motivated to start the site by his approach to investing, the report said.
"I'm a firm believer that out of (the more than 10,000) public companies, the odds are that there are more than just a few crooks and frauds," Cuban was quoted as saying. "Finding them can be rewarding and entertaining."
Cuban, however, did not disclose how much he was investing in the site, the report said.
