Risk parity is Ray Dalio's answer to a problem he states bluntly: the investor who concentrates in any one asset class is eventually destroyed. "Every major asset class had great and terrible decades, so much so that any investor who had most of their wealth concentrated in any one investment would have lost almost all of it at one time or another." His Bridgewater "All Weather" framework is the construction that tries to hold steady through all of them.

The intellectual core is a rejection of the conventional capital-allocation logic. Dalio's Principles pits the learned against the logical: the passage contrasting reasoning-based thinkers with memory-based ones names CAPM as the learned idea and All Weather as the logical one — the portfolio that does not depend on forecasting which regime comes next. The operational rule appears, almost identically, in two places. In Principles: "Don't bet too much on anything. Make 15 or more good, uncorrelated bets." And in How Countries Go Broke, where he calls it the Holy Grail of Investing — finding and making 15 or more great uncorrelated bets — immediately prefaced by the risk posture that justifies it: "I control risks through diversification of my good risky bets rather than by avoiding risky bets."

Two things distinguish this from ordinary diversification. First, the goal is balance of risk, not balance of capital: the point is that no single environment — not a particular asset class — dominates the portfolio's losses. Second, it is built for ignorance of timing. Dalio's description of how to survive paradigm shifts reduces to three choices: time the ins and outs, "faded the moves (i.e., bought more when prices fell and sold more when prices rose), or had a balanced portfolio that would have held relatively steady through the moves. The worst thing would have been to go with the moves (sell after price declines and buy after price increases)." Risk parity is the third option institutionalized — a portfolio that does not require the investor to be right about the next decade.

This is a different risk philosophy from the rest of the corpus. Where permanent-loss-of-capital treats volatility as a tolerable byproduct of buying undervalued assets, risk parity treats concentration itself as the enemy and spreads exposure precisely so that no single loss can be permanent. The two agree that the future's direction is unknowable — Dalio's paradigm shifts are cycles at their longest wavelength — but they diverge on whether the answer is a balanced basket or a concentrated bet on undervaluation with a margin-of-safety.

A scope note: the Dalio materials in this corpus state the all-weather principle — the uncorrelated-bets rule and the balanced-portfolio argument — but do not contain the specific All Weather weightings (the familiar ~30% equities / ~55% bonds / 15% gold and commodities construction is not present in the ingested documents). No such figures are reproduced here; the page is grounded only in what the corpus states, hence confidence: medium. See asset-allocation for the strategic/tactical frame this strategy inverts.
