Beyond P/E: Why SIRRIPA Is the True Safeguard for the S&P 500
Abstract
With a SIRRIPA of 5.47%, clearly above the risk-free rate of 4.223%, the S&P 500 remains fundamentally supported—despite being labeled “overvalued” by conventional metrics. This explains why SIRRIPA has provided a more accurate and actionable signal than the P/E ratio, PEG, or earnings yield during the recent market cycle.
