Ms. Ears is an investment adviser representative. During lunch today, she overheard two men talking about a hostile takeover that their firm was preparing to undertake. Based on this information, Ms. Ears does not hesitate to advise the client she meets with immediately after lunch-Mrs. Clueless-- to invest a sum of money in the firm the men had named as the target firm. Ms. Ears remembers that the price of target firms, on average, increases significantly with an announcement of this sort, but she does not inform Mrs. Clueless of the reason underlying her recommendation. Has there been any violation of insider trading laws in this scenario, as described?
