Analysts noted that liquidity constraints and evolving credit risk assessments have weighed on investor confidence, particularly for institutions with concentrated regional exposure.

Back-testing parameters for FCNCA require precise execution conventions to isolate performance drivers. A typical U.S. listed equity approach using dollar volume as a liquidity filter suggests potential during high-impact news cycles. However, the absence of transaction cost modeling in current frameworks limits the accuracy of short-term predictive models, especially for thinly traded assets.

To rigorously assess FCNCA’s performance, a using external code is recommended. This would involve scripting selection criteria and to capture daily top-500 volume dynamics. Alternative methods, such as proxy indices like the S&P 500 Equal-Weight ETF (RSP), offer faster execution but may dilute precision in capturing idiosyncratic stock behavior.

Proposed next steps include finalizing the implementation route: either a full multi-asset back-test with custom code or a proxy-based approximation. Transaction cost modeling and extended holding period analysis could be added for enhanced realism, pending stakeholder approval.
