A secondary method of data collection was adopted. A purposive sampling technique was used in selecting six of the eight SIBs in Nigeria. An ex-post facto research design was employed. The variables tested for financial information were earnings per share (EPS) and book value per share (BVPS), while the average market per share (AMPS) was used as the proxy for stock price changes. Data gathered from the audited financial statements of the selected SIBs were African Journal of Business and Economic Research (AJBER) (Online) ISSN 1750-4562 (Print) ISSN 1750-4554 Indexed by SCOPUS, IBSS, EBSCO, ProQuest, ABDC, SAJE, COPERNICUS, CABELL, Sabinet and J-Gate.
