Since the global financial crisis in , risk management has particularly become more important than performance management in portfolio optimization. The alternative risk parity portfolio design has been receiving significant attention from both the theoretical and practical sides because it - diversifies the risk, instead of the capital, among the assets - is less sensitive to parameter estimation errors. Today, pension funds and institutional investors are using this approach in the development of smart indexing and the redefinition of long-term investment policies.
Risk parity or risk premia parity is an approach to investment management which focuses on allocation of risk, usually defined as volatility, rather than allocation of capital. 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 observed in Q1 , which led to the significant underperformance of risk-parity funds in the Covid19 sell-off. Roughly speaking, 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. Some of its theoretical components were developed in the s and s but the first risk parity fund, called the All Weather fund, was pioneered in In recent years many investment companies have begun offering risk parity funds to their clients.
Introduction to Risk Parity and Budgeting arXiv The weights of the minimum variance portfolio are: x? We notice that x? This is normal because the first and second as- sets present the same characteristics in terms of expected return, volatil- ity and correlation with the third asset. The cost of this constraint is larger for the minimum variance portfolio.
Risk parity is an allocation method used to build diversified portfolios that does not rely on any assumptions of expected returns, thus placing risk management at the heart of the strategy. This explains why risk parity became a popular investment model after the global financial crisis in However, risk parity has also been criticized because it focuses on managing risk concentration rather than portfolio performance, and is therefore seen as being closer to passive management than active management. In this article, we show how to introduce assumptions of expected returns into risk parity portfolios. To do this, we consider a generalized risk measure that takes into account both the portfolio return and volatility.

Risk parity then became a popular financial model of investment after the global financial crisis in Today, pension funds and institutional investors are using this approach in the development of smart indexing and the redefinition of long-term investment policies. Introduction to Risk Parity and Budgeting provides an up-to-date treatment of this alternative method to Markowitz optimization. It builds financial exposure to equities and commodities, considers credit risk in the management of bond portfolios, and designs long-term investment policy. Thierry Roncalli's excellent book " Introduction to Risk Parity and Budgeting " details the theory of portfolio optimization and risk parity as well providing application to many different asset classes.
