I had no intention of buying PC's or anyone else's service, but I was curious what the sales pitch was. So I listened to it about three years ago. I thought I kept the slides but can't seem to find them now.
(1) The sales rep (aka financial advisor) was unable to discern a strategy from my holdings. It was and is an cash flow-focused portfolio, but PC wasn't able to understand that.
(2) The pitch for holding equal weight of sectors was based on the tech bubble in 1999 and the financial/housing bubble in 2007. Each time, the S&P 500 was dominated by those sectors, so a rotation out was, in hindsight, not as bad passively holding the index.
(3) Domestic equity holdings consist of ~85 individual stocks, with at least two similar companies for each industry. For example, the portfolio might alternate between T and VZ or COP and XOM. 85 companies seems like a lot to keep track of, so my conclusion was PC just bounced back and forth between the pairs hoping both would go up or, if they went down, there would be some tax loss harvesting.
(4) I believe foreign holdings were in the form of an ETF or mutual fund, but I cannot remember.
(5) Bond holdings (domestic and foreign) were ETFs or mutual funds. Again, PC bounced between funds.
I was never interested in giving PC any money, so I cannot say how successful they would have been.
