It would appear that MFSA is a pay for service side hustle of Motley Fool. The cost is $100 per year. I tried to find out more about it this morning but have not been able to without signing up. I hate having to sign up for anything with a fee in order to find out the nitty gritty details, or even the most basic of info. Even if they offer a full refund after some trial period. Is it just a newsletter? Is it an investment club? Who knows how it works?
The way I look at it, if I were to try it out by investing $10,000, with "fees" $100 per year, that ends up being the equivalent of an 1% AUM. Not counting any other "fees" which are not disclosed before signing up.
Send them your email from one of their teaser ads and eventually they'll send you an offer for $49 a year. There are no other fees. Sure, if you don't invest much the fee seems higher. I had probably $200K-$300K in their stocks at one time. That makes my fee what, .0005%. And actually after that first year it was only $49 so half that. And since I still hold many of their stocks 10 years since I last subscribed those years I paid nothing. But I make my own decisions when to sell.
It's not for everybody, but if you use it like I did, strictly as a place to get ideas, then do your own research from there it can be quite helpful.
