In plain terms

Tests whether a stock follows other companies headquartered in its home state when they trend.

How it works

Propagates 21d momentum across the same-US-state HQ graph. The factory explicitly treats same-HQ-state as having NO information-diffusion lead-lag basis (every directional cell scored net-negative vs buy-hold), so this is an exploratory directional spillover retained only for completeness.
