I am an investment contributor for U.S. News & World Report and working on a story about the various instances when it’s time to sell a stock. This slideshow is bound to get excellent play. All we need are bullet points (three or more are excellent) with one-paragraph explanations *via email* explaining when and why it’s time to sell a certain stock. As many such tips may be obvious, try to come up with original or lesser-known reasons, such a particular kind of or specific current event (though stock answers are also welcome, too). So that I don’t lose your email, put REASONS TO SELL A STOCK, all caps, in the subject line. Identify the name of the person quoted as it should appear in print, the person’s title and where they are based. Deadline for responses is end of day March 30.
