XTAL Private Market
α-β Cen Indices

Duration-adjusted private market benchmarks — physically representative, derivative-ready, and computed daily. The only index methodology for private capital that is aggregation-consistent in present-value space and structurally replicable in investable instruments.

Named after Alpha and Beta Centauri, the two brightest stars of the Centaurus constellation. Navigators know them as the Pointers: the stars that locate the Southern Cross and fix a bearing south. The name carries a second reading — when navigating between investment alternatives, knowing where alpha and beta sit matters just as much, particularly when it gives early warning of valuations heading south.

XTAL Private Equity
Illiquidity Cost Index

Measures the daily change in the premium or discount of a select group of Listed Private Equity Trusts and Companies, and aims to infer the cost of the illiquidity of a diversified buyout private equity portfolio. Published in price terms and independent from any currency denomination.

A positive index percentage change represents the decrease in the illiquidity cost to sell a diversified portfolio of buyout PE funds, given the NAVs of the underlying funds are available at the time of measurement.
