You often hear market commentators discuss that whenever the yield curve increases, stock prices would fall because a higher discount rate should lead to lower valuation. In 2021, you observed that the entire nominal yield curves shifted upwards i.e., nominal yields increased across all maturities. However, equity markets continued their runs to an all-time high.
