Last month I wrote here that although there are virtually no “repeatable” ways to legally trade and profit off of inside information, every once in a while a scenario or idea emerges that puts that proposition to the test. I cited two examples: (1) the recent assertion that some people have early access to, and can trade in advance on, releases on PR newswire services, and (2) Mark Cuban’s Sharesleuth.com business model, which involved him hiring a business reporter to conduct investigations to “identify suspect companies,” Cuban selling short based on the findings, and then Sharesleuth.com publishing reports showing all of the damning evidence (and the stock price of the company involved falling).
