What are the criminal penalties for insider trading?
In addition, violators are usually charged with mail and wire fraud (which can lead to a sentence of up to 20 years in prison), more general "securities fraud" (up to 25 years in prison), and possibly even racketeering, tax evasion, and/or obstruction of justice. You can also expect civil penalties to result from the SEC's enforcement action.
Prison terms for insider-trading convictions have lengthened in recent years. According to The Wall Street Journal, from 2009 to 2011 the median jail sentence was 30 months, up from a median term of 18 months during the 2000s. From 1993 through 1999, the median length of prison terms was only just under a year.
