I use a number of Leveraged ETFs - this doesn't really support those.
Doesn't work for me

Premium analytics are ignorant of ETFs. For example, portfolio characteristics feature just looks at single stocks (if any) that you have. It would be simple, and analytically correct, to treat ETFs as if they're a portfolio of appropriate weights of the relevant single stocks (eg, if I own SPY, you should pretend I own 500 separate positions of single stocks in appropriate weights), but Yahoo Premium just ignores the ETFs.
