It seems that WMA's old Portfolio manager has quietly slipped away to Dexus: https://www.linkedin.com/in/daniazinurova/?originalSubdomain=au
I couldn't find this being announced anywhere. Maybe it explains the recent SP weakness.
I still think WMA is good value at the current discount to NTA, given that it's near impossible to replicate the underlying exposures for a retail investor. Although paying double fees is pretty crap.
There is a vote coming up next year that would involve dumping WAM as the manager and winding up the fund. It would require a 75% vote in favour. I don't think this vote will get up, although it probably should.
