This study examine the reactions in different portfolios under demographic changes for a deeper scope of the equity market. By six features: 1) beta 2) volatility 3) non-systematic risk 4) size 5) B/M 6) D/P, we distribute stocks into high or low level groups and test the reactions in each of these 12 portfolio. Empirical results in this study do suggest an increasing required risk premium for a growing population in retired-age (65+) group and a decreasing required risk premium for a growing population in middle-aged (44-64) group. Both effects in middle- and retired-age groups are stronger in a long time-horizon. Changes in demographic structure significantly add explanatory power to equity premium regressions involving Fama-French three factors. Moreover, we found retired-age population significantly demand more premium for high volatility stocks, growth stocks and large-cap stocks. However, there is no preference for any types of stock in middle-age population.
