The proxies for measuring pension fund assets included ordinary shares, government securities, corporate debt securities, money market instruments, real estate property and other securities. To achieve the stated objectives, the study adopted the exploratory research design and employed the ordinary least square (OLS) estimation technique within the modelling framework of autoregressive distributive lag (ARDL) analytical methods in testing and in the estimation of the relevant equations. The findings from the analyses revealed that the relationship between pension fund assets and real capital market capitalization in Nigeria was found to be positive and significant in the long run as well as in the short-run.
