I've received a lot of those invitations. But I've always thrown them away. I always supposed that they took your contact information and then harassed you like crazy. I really don't want to get on their email or phone list. But is it actually safe to attend these things? (I mean, safe as long you don't buy what they're selling)We've attended a bunch of those as it has helped DH to have a better understanding of the investing world. He tends to glaze over when I talk about finances, and he absorbs more from those presentations, so they serve a useful purpose for us. I also find that I can generally learn at least one thing from them, or confirm my knowledge in something.They are definitely looking for new clients, and typically ask you to make an appointment if you are interested at the end. If not, it ends right there, and most of them are pretty upfront about not feeling offended if you don't want to make an appointment because they don't want to waste either their time or your time.I've never been harassed afterwards by any of these folks, and I have taken them up on a few of the individual appointments where they analyze your assets and investments, and come back with recommendations and a plan they'd like to put into place. I have found that the ones that call themselves "Financial Planners" are much more likely to be selling annuities, but the ones that are clearly brokers working for a large brokerage tend to want to put you into stocks and sometimes their proprietary funds.We haven't been to one of these in a while, but they have proven useful to us just because they have really helped to get DH to understand more about finances.
