This is an interesting short read from Morninsgtar.

As a matter of interest, I did not recommend Neil Woodford’s new fund instead of his Invesco Perpetual one when I was an IFA. My thinking was that as a charismatic individual of strong views, his style represented more of a risk when he was the top guy in his own firm! I also thought he might get distracted by management issues, although he did appoint others to deal with the main mundane business functions. Being his firm with his name on it, he was always going to have to get involved in day to day issues of business at least some of the time.
I did endorse Jason Pidcock’s new fund at Jupiter and still like it. Jupiter allow their managers considerable style freedom but are still a large enough firm to have the appropriate peer review and risk control mechanisms.
