Stock prices decline due to a wide variety of interconnected macroeconomic, sector-specific, and company-level variables, including disappointing quarterly earnings reports, downward revisions of future revenue guidance, and rising interest rates that reduce present-day valuations of future cash flows. Additionally, broader market sell-offs, institutional capital rotations out of specific sectors, regulatory headwinds, or unexpected geopolitical shocks can trigger heavy selling pressure, driving down equity valuations across public exchanges.
