You have to look at the portfolio as a whole. When stocks fall 50% you'll be glad to have some cash because:

1. You'll be down less than 50%

2. You'll be able to buy more stocks at a discount (via rebalancing)

I wonder if this has been back tested? The advantages of 1 and 2 don't seem to be a good trade for 25% fewer gains in the majority of years.

It's a well known portfolio so it has been analyzed quite a bit.

You can backtest it yourself:

- portfolio 1 is all stocks

- portfolio 2 is 75% stocks, 25% cash

- portfolio 3 is the "Harry Browne Permanent Porfolio" (selected from the "lazy portolios" option)

Take a look at the "drawdowns" tab.
