Hard to say. But as regular user, I'm sure it's popularity/specialness is not common knowledge for unfamiliar/non users.
I mentioned elsewhere that my spouse killed it against the SP500 in recent years, with partly her own stock selections. Things that I wouldn't want to own or I'd eternally be waiting for the right price, companies like Amex, Hilton, Home Depot, Aritizia, etc. So I kinda appreciate that she gives is curveball to our family portfolio. She's also kinda timid with position sizing, so her losers don't end up being so harmful.
