Risk Parity

Balancing portfolios by risk contribution instead of rupee weight. Why equal money is not equal risk.

Risk parityAllocating so each asset contributes equal risk. is a portfolio-construction approach that allocates by risk contribution rather than by rupee amount. Instead of “putThe right, not the obligation, to buy or sell at a set price. equal money in each asset,” it asks “let each asset contribute equal risk to the portfolio.”

The key realisation: equal money is NOT equal risk. A “balanced” 50/50 stocks/bondsA loan to a government or company that pays fixed interest. portfolio sounds diversified, but because stocks are far more volatile than bondsA loan to a government or company that pays fixed interest., the stocks contribute the vast majority (often ~90%) of the portfolio’s actual risk — it’s really a stock portfolio in disguise. Risk parityAllocating so each asset contributes equal risk. fixes this by sizingDeciding how much to bet on each trade or holding. positions *inversely to their volatilityThe size of price swings — not their direction.: you hold more of the calm assets (bonds) and less of the wild ones (stocks) so each contributes the same amount of risk — producing a portfolio that is truly balanced in the dimension that matters (risk), not the one that’s merely easy to see (money). The payoff is a smoother, more genuinely diversified ride; the trade-off is that it often requires leverageControlling a large position with a small amount of money. on the low-risk assets to reach a desired return level, which adds its own risks. The deep lesson stands regardless: think in risk contribution, not rupee weight* — measuring balance by money allocated quietly leaves you concentrated in your riskiest holdings.
ExampleA 50/50 stocks/bondsA loan to a government or company that pays fixed interest. portfolio feels balanced, but if stocks are ~4× as volatile as bondsA loan to a government or company that pays fixed interest., stocks drive ~90% of the swings — a market crash hits it almost like an all-stock portfolio. A risk-parity version might hold far more bonds and fewer stocks (sometimes levered) so each contributes ~50% of the risk — a ride that’s genuinely, not just nominally, balanced.
Key takeawayRisk parityAllocating so each asset contributes equal risk. allocates by risk contribution, not rupee weight, because equal money ≠ equal risk (a 50/50 stock/bondA loan to a government or company that pays fixed interest. mix is ~90% stock risk). It sizes inversely to volatilityThe size of price swings — not their direction. for a truly balanced ride — often needing leverageControlling a large position with a small amount of money. to hit return targets. The universal lesson: think in risk contribution, not money allocated.
FAQs
Is risk parity better than a simple 60/40 portfolio?

It’s more *genuinely* balanced by risk and historically smoother, but it’s not free of issues — it typically relies on leverage and on bonds behaving as a diversifier (which can fail when stocks and bonds fall together). Even if you don’t implement full risk parity, its core insight — measure and balance by *risk contribution*, not rupee weight — improves almost any portfolio.
