Risk paritySuccessive convex optimizationSince the 2008 financial crisis, risk management has become more important and portfolio approaches, such as the minimum-variance and equally weighted portfolios, have gained popularity. However, such portfolios still do not diversify the risk in the true sense....
We proceed to use this model for risk parity optimization and also consider the construction of a robust version of the risk parity optimization by introducing uncertainty structures to the estimated market parameters. We test our model by constructing a regime-switching risk parity portfolio based ...
Risk parity is a type of asset allocation strategy that has become increasingly popular in the aftermath of the global financial crisis.风险平价是一种资产配置策略,在全球金融危机之后变得越来越流行。Risk parity is an advanced portfolio technique often used by hedge funds. It typically requires quantita...
Extending the risk parity approach to higher moments: is there any value added? The Journal of Portfolio Management, Vol. 43(2), 24 – 36. Fabozzi, J. F., P. N. Kolm, A. P. Pachamanova, and S. M. Focardi (2007). Robust portfolio optimization and management. New Jersey, Hoboken:...
This paper formulates a relaxed risk parity optimization model to control the balance of risk parity violation against the total portfolio performance. Risk parity has been criticized as being overly conservative and it is improved by re-introducing the asset expected returns into the model and permi...

at least a part of the portfolio could weather each risk. So this is where the All Weather is similar to risk parity: Instead of targeting optimal risk and return in the traditional portfolio optimization setting, both strategies strive to achieve balanced risk contributions from all asset ...

Finding the weights for the assets is not as easy as with naïve risk parity. The weights are calculated using the following convex optimization: where capital Sigma is the covariance matrix. The following figures show a portfolio consisting of SPY, EFA, GLD and IEF ETFs created using Equal ...
