A pair of analysts at Lyxor Asset Management have a request for index vendors: create a new generation of multi-asset class benchmarks. “The need of such indexes is crucial for all investors that manage multi-asset classes,” write Rodolphe Louis and Thierry Roncalli. “Today, it is unthinkable to manage an equity or a fixed-income portfolio without a reference to a benchmark. And this benchmark is generally an index representing the market portfolio.” It’s time for a renewed focus on stock/bond indexes, they assert.
