When Is It Appropriate to Pass On A Rumor?

A friend has said that she is going to invest with a certain money manager about whom you have heard negative things.  But you don’t know for SURE that those things are true or not.  Should you remain silent?  Telushkin suggests that there is an ethical and unethical way to pass along hearsay information.  Say to your friend that you have heard that So-and-so’s record is a bit spotty, maybe it would be wise to check with a couple of his clients before you invest your hard earned cash.  This puts the ball in her court, but also let’s her know that the information you are passing along is hearsay.  One could argue, I suppose, that you might give your friend a fabricated warning - but that would be lying, and, so not fall under this idea.  Lying is never a good idea, although sometimes it’s okay to not tell the truth.  I’m pretty sure this topic was dealt with earlier…
