“…After in-depth analysis using explanatory, inferential statistics and multiple regressions, the study made conclusions that a majority of banking institutions, along the years had in tandem adopted insurance investment, government securities, shares from exchanges, as well as bonds to enhance their profitability and subsequently better returns to their shareholders. Olarewaju et al (2018) did scrutiny on the impact of operational diversification on banking performance using the pooled, FEM, REM, and System GMM for a duration ranging from 2006 to 2015 and were across two hundred and fifty commercial banks from 30 nations in the region of Sub-Saharan Africa. As a result of strength of robustness of SYS-GMM, it was revealed in the outcome of this assessment that using Herfindahl Hirschman index, every component relating to operational diversification that included; deposit, revenue, asset, liability, and deposit inclusive of control variables like bank size, ratios of liquidity, loan-loss ratio, cost-income ratio and the lagged return on average asset were deemed significant at 1% level having only deposit diversification (HHIde), which had a negative link with ROAA.…”
