Not sure I agree entirely that they are that independent, newageinv.
I haven't done any exhaustive research on Weiss, but it seems from a quick glance that they have been in this space a while already.
So, basically, when it comes to rating assets, it would seem they are accustomed to rating markets which are - at least to one degree or another - rigged. A tell-tale sign is they don't feel the need to provide fuller details on their findings.
As for it being free... I don't know how they would survive by doing all that work without charging for it, right? I mean otherwise they'd be a charity. Or they're a front for the 'winners' in the rigged system.
And, if you do make any sales reporting on who winners are, in a rigged market, well .... then surely you have implicated yourself.
That's my opinion, anyway. I wouldn't be too quick to assume their independence. Perhaps a good starting point would be to ask independent from what/who?
