Which one of the following statements is among the empirical findings of Hou, Xue and Zhang's (2015) q-factor model? When Fama and French's HML factor is regressed on the factors in the q-factor model, the alpha is significant. This result suggests that the q-factor model cannot explain anomalies related to the book-to-market and other valuation ratios. When the momentum factor UMD is regressed on the factors in the q-factor model, the alpha is significant. This result suggests that the q-factor model cannot explain the momentum anomaly. When the profitability factor RROE is regressed on Fama and French's three factors, the alpha is significant. This result suggests that Fama and French's three factors cannot subsume the profitability anomaly. When the investment factor RH/A is regressed on Fama and French's three factors, the alpha is insignificant. This result suggests that Fama and French's three-factor model can explain the investment anomaly well
