About the Permanent Portfolio strategy

Harry Browne's Permanent Portfolio divides capital into four equal parts: stocks, long-term Treasuries, cash, and gold. Each is meant to thrive in a different economic condition — prosperity, deflation, tight money, and inflation — so that something in the portfolio is usually working.

This backtest uses VTI, TLT, BIL, and GLD at 25% each, rebalanced annually. The large cash and gold weights make it one of the most conservative classic allocations, prioritizing capital preservation and low drawdowns over growth.

It appeals to investors focused on stability and protecting capital across very different market environments, rather than on maximizing long-term returns.
