Columns (1)--(6) correspond to the row variables in the same order. The three AI signals are mutually highly correlated (pairwise $\rho$ between 0.74 and 0.86), consistent with their being three lenses on a single latent ``AI salience'' construct, whereas each AI signal's unconditional correlation with the forward return is small ($\approx 0.04$), foreshadowing that the action lies in the time variation of the relation rather than its unconditional level.} \end{table}
