I inherited a portfolio that Fisher was managing at Fidelity a decade ago. I had previously attended a few events at Ken Fisher's fine home and hear him speak when he hosted clients several years earlier.
I kept the portfolio for about a year, the service and performance were mediocre. They provided a lot of info and prognostications with their monthly reports, which was impressive to many clients I suppose. They actually tracked their performance relative to a benchmark, a very rare step toward accountability in my experience. They seemed to adjust the benchmark periodically, and of course cherry picked timing and asset classes favorably. The performance wasn't terrible, mostly lagging the market by a bit more than the AUM fee, 1.25% or 1.5% I recall.
Their tone became defensive, escalating to rude and almost hostile as I advised them of my plans to invest elsewhere, fairly typical. I suppose they black listed me from their marketing blitz, how unfortunate.
I had been a DIY Boglehead investor for many years, but was impressed by another highly recommended FA, and gave him a shot with this portfolio for a year or two. Again, lagging the market by the AUM plus a couple points. Again, lots of protests, counter arguments, and scare tactics when moving out.
I'm much better off since then with a simple, low cost, DIY portfolio. There's just no reason to split my retirement withdrawal rate with a FA who is almost certain to lag the market.
Edit:
One point to add: The Fisher performance noted and my decision to leave were based on 10-12 years of account statements, not just the one year they managed a portfolio for me.
