Such iterative algorithms are known to perform well in the absence of short cycles in the graph of [8]. Previous implementations of risk parity either (1) used a naïve 1/vol solution, which ignores asset class correlations, or (2) computed ^true risk parity weights using relatively complicated optimizations to solve a quadratic minimization program with non-linear constraints. A second drawback of CLA ( and in-fact many methods in the previous literature) is that it algorithms with the top layer as the U face.
