This study demonstrates that both investor identity and trading intensity determine the High Volume Return Premium, but intensity effects only emerge when measured correctly. Using Korean market data (2020-2024), we show that institutional buying intensity normalized by market capitalization reveals a perfect monotonic relationship with future returns (Q4: +10.07\%; Q1: -0.05\%), while trading value normalization fails. Retail investors exhibit an inverted pattern, confirming noise trader behavior. This reconciles decades of conflicting evidence: intensity matters profoundly, but requires (1) investor-type conditioning, (2) nonlinear quartile analysis, and (3) conviction-based (market cap) rather than participation-based (trading value) measurement.
