What This Means
This is commentary, not reporting of a market event. The piece argues that traditional economic indicators no longer reliably predict equity performance, suggesting structural shifts in how markets price risk and opportunity. The mechanism matters for portfolio construction: if economic data loses predictive power, investors must rely on alternative signals—monetary policy, sentiment, liquidity flows—to guide allocation.
