Risk Parity Investing: Unlocking Portfolio Balance

Risk parity is an advanced portfolio technique used by hedge funds and sophisticated investors. It is a conceptual approach to investing which attempts to provide a lower-risk and lower-fee alternative to the traditional portfolio allocation of 60% in shares and 40% in bonds. Risk parity focuses on the allocation of risk, usually defined as volatility, rather than the allocation of capital. The goal of risk parity investing is to earn the optimal level of return at the targeted risk level.

Risk parity is a conceptual approach to investing

The risk parity approach asserts that when asset allocations are adjusted (leveraged or deleveraged) to the same risk level, the risk parity portfolio can achieve a higher Sharpe ratio and can be more resistant to market downturns than the traditional portfolio. Risk parity is vulnerable to significant shifts in correlation regimes, such as those observed in Q1 2020, which led to the significant underperformance of risk-parity funds in the Covid-19 sell-off.

The approach of building a risk parity portfolio is similar to creating a minimum-variance portfolio subject to the constraint that each asset (or asset class, such as bonds, stocks, real estate, etc.) contributes equally to the portfolio's overall volatility. Simplified allocation strategies such as the 60%/40% stocks-bonds portfolio make use of MPT. MPT provides a standard for diversification within one's investment portfolio that maximises expected return for a given level of risk. In simplified MPT strategies using just stocks and bonds, allocations are usually more heavily weighted toward equities for investors who wish to take on more risk.

Risk parity is an advanced portfolio technique

Risk parity is a portfolio allocation strategy that uses risk to determine allocations across various components of an investment portfolio. It modifies the modern portfolio theory (MPT) approach to investing through the use of leverage. MPT seeks to diversify an investment portfolio among specified assets to optimise returns while adhering to market risk parameters. With risk parity strategies, portfolio managers can derive exact capital contribution proportions of asset classes in a portfolio to achieve optimised diversification for a range of objectives and investor preferences.

The easiest way to envision this concept may be to consider it in the context of a traditional, diversified portfolio. For many investors, this portfolio is represented by defined percentage allocations across stocks and bonds. Such a balanced portfolio, for example, may allocate 50% of its assets to stocks and 50% to bonds in an effort to achieve diversification.

The goal of risk parity investing is to earn the optimal level of return at the targeted risk level. It modifies the modern portfolio theory (MPT) approach to investing through the use of leverage. MPT seeks to diversify an investment portfolio among specified assets to optimise returns while adhering to market risk parameters by viewing the risk and returns for the entire portfolio, but only utilising long and unmargined positions.
