Can you get prosecuted as a senator for insider trading if you buy an ETF? If the senator used insider information and bought an ETF that had a big holding of a stock that went up as a result of an action only insiders would have known, can you get charged for insider trading, or would it be too difficult to make a case for it given that most ETF are well diversified? I am thinking even if the ETF had 10%+ holding, there wouldn't seem to be big case for insider trading if someone were to buy an ETF with a large holding of a particular stock. Am I wrong?
