If an investor in a company receives a private request from the company CEO to invest additional capital, should the investor be able to sell her existing stock if she concludes that the request indicates that the company is having financial problems? Assume that her conclusion is based on the way in which the request is made - tone of voice, choice of words, etc. - and that it turns out that her conclusion is correct so that she sells before the problems are known to the public. "Should" means not whether you think the law permits or forbids it, but whether you think the law should permit or forbid it. Consider the implications for society and capital markets.
