Bridgewater All Weather
All Weather is Bridgewater Associates' risk-parity fund, launched in 1996 out of Ray Dalio's argument that a portfolio should be balanced by each holding's contribution to risk rather than by dollars invested. It allocates across four regimes — growth and inflation, each either rising or falling — so that no single macroeconomic environment dominates returns, and it is the template most later risk-parity products copied.
