I got the info from the Permanent Portfolio web site. Not from the book. The book never mentions PRPFX as far as I know.
When I went to google the address I can't find the exact address to give you. But the info is correct. I copied the allocations this afternoon just before I posted. perhaps 2040 can adjust his PRPFXC plus judicious purchase of etfs to mimic nthe IVY portfolio
One table in the book compares periods of readjustments/rebalancing. It shows every 5 years a rebalancing returned higher returns. Possibly letting winners ride
