BX/Nitrogen Models: Open Architecture. Non-Proprietary.
Risk-Disciplined.

The BX/Nitrogen model suite is a set of globally diversified, risk-aware portfolios designed to deliver strong risk-adjusted outcomes across market environments. This launch includes twelve models spanning four risk profiles — from Moderately Conservative to Aggressive — and three distinct structural approaches: Global, U.S. Only, and ETF Only.

Each model is built using an open-architecture, non-proprietary framework and incorporates a differentiated blend of individual stocks and ETFs where appropriate.

DISCLAIMER
Performance Disclosure

All indexes, models, and research provided are strictly for financial professional use only and not to be shared with the public. Indexes and models are licensable through BX Index by financial professionals.

Please see the model and index fact sheets for more information about any specific index, including launch date. Some of these indices contain data that reflect “hypothetical” or “back-tested” returns. All information prior to an index’s launch date is hypothetical (back-tested), not actual performance, and is based on the index methodology in effect on the index launch date applied to the universe at the time. Complete index methodology is available upon request. Back-tested performance reflects application of an index methodology and selection of index constituents with the benefit of hindsight and knowledge of factors that may have positively affected its performance and may be considered to reflect survivor bias. Actual returns may differ significantly from, and be lower than, back-tested returns. Past performance is not an indication of future results. Back-tested performance is for use with institutions/financial professionals only and is not for use with retail investors.

Index and model returns do not represent the actual trading of investable assets/securities. Index One maintains the index and calculates index levels and performance shown but does not manage actual assets. Returns shown do not reflect any sales charge or investment management fees that may have been paid.
