The back-testing analysis requested by users revealed critical limitations in single-ticker strategies for multi-asset portfolios. The current engine supports only per-ticker simulations, making it unsuitable for strategies involving daily rebalancing of the top 500 volume stocks. Two alternatives were proposed: (1) using a proxy index like SPY to approximate large-cap momentum effects, or (2) executing a custom multi-asset back-test requiring extensive data aggregation and computational resources. Both approaches aim to address the inherent complexity of replicating real-world portfolio dynamics within constrained analytical frameworks.
