With the aim of addressing long-standing challenges in tracking private equity alongside public markets, MSCI has launched the All Country Public + Private Equity Index, a daily measure integrating global public equity benchmarks with private market data.

The index will combine MSCI’s flagship ACWI IMI, which covers USD 5.6 trillion in publicly listed equities across developed and emerging markets with the MSCI All Country Private Equity Index, based on cash flows and valuations from nearly 10,000 private equity funds.

The launch comes as institutional investors increasingly expand private equity holdings to boost diversification and long-term returns.

Head of Private Assets at MSCI, Luke Flemmer saidthe index is a milestone in MSCU mission to make private markets more transparent and accessible.

“It reflects MSCI’s unique combination of high-quality data, world class research and index distribution capabilities and extends our private assets toolkit that gives investors a simpler way to access, benchmark, and allocate to private capital,” Flemmer said.

The index targets a 15% allocation to private equity and will be calculated daily using drifted weights, with quarterly rebalancing that incorporates the latest fund-level data while aiming to maintain consistency with MSCI’s methodology.

In each review, the latest available component index data will be incorporated, and the weighting factors will be reset to the target allocation.

Furthermore, rebalancing is going to be conducted in accordance with MSCI’s index maintenance policies providing continuity and comparability over time.
