The aim of this study was to determine the effect of income diversification on the financial performance of commercial banks in Sierra Leone. A descriptive research design was adopted. A census targeting the listed commercial banks in Sierra Leone from the year 2018 to 2022 was conducted. The statistical significance of each independent variable was tested by performing a t-test at a 5% level of significance. The significance of the regression model was tested by performing an F-test at a 5% significance level. The independent variables' explanatory power was evaluated using the coefficient of determination, R^2. The study found that income diversification was negatively related to financial performance. The results of the t-test indicated that the effect was not statistically significant. It also found that size and capital adequacy had a positive effect, which was statistically significant, while liquidity had a negative impact on financial performance and was not statistically significant. The coefficient of determination for the regression was found to be 35.7%. This implies that the independent variable explained only 35.7% of the changes in the dependent variable. The study concluded that income diversification is a costly affair for commercial banks since it has a negative impact on financial performance. It also concluded that size and capital adequacy had a positive impact on financial performance while liquidity had a negative impact. This study recommends that commercial banks should not commit resources to diversifying their income because diversification appears to be a costly affair. Also, investors should not be concerned about a bank’s income diversification in selecting investment opportunities as diversification of income does not generate positive financial performance.

EFFETS DE LA DIVERSIFICATION DES REVENUS SUR LA PERFORMANCE FINANCIÈRE DES BANQUES COMMERCIALES COTÉES EN SIERRA LEONE
L'objectif de cette étude était de déterminer l'effet de la diversification des revenus sur la performance financière des banques commerciales en Sierra Leone. Un plan de recherche descriptif a été adopté. Un recensement ciblant les banques commerciales cotées en Sierra Leone de l'année 2018 à 2022 a été réalisé. La signification statistique de chaque variable indépendante a été testée en effectuant un test t à un niveau de signification de 5 %. La signification du modèle de régression a été testée en effectuant un test F à un niveau de signification de 5 %. Le pouvoir explicatif des variables indépendantes a été évalué en utilisant le coefficient de détermination, R^2. L'étude a révélé que la diversification des revenus était négativement liée à la performance financière. Les résultats du test t ont indiqué que l'effet n'était pas statistiquement significatif. Il a également été constaté que la taille et l'adéquation des capitaux avaient un effet positif, qui était statistiquement significatif, tandis que la liquidité avait un impact négatif sur la performance financière et n'était pas statistiquement significative. Le coefficient de détermination pour la régression a été trouvé à 35,7 %. Cela implique que la variable indépendante expliquait seulement 35,7 % des changements de la variable dépendante. L'étude a conclu que la diversification des revenus est une affaire coûteuse pour les banques commerciales car elle a un impact négatif sur la performance financière. Il a également conclu que la taille et l'adéquation des capitaux avaient un impact positif sur la performance financière tandis que la liquidité avait un impact négatif. Cette étude recommande que les banques commerciales ne devraient pas engager de ressources pour diversifier leurs revenus car la diversification semble être une affaire coûteuse. De plus, les investisseurs ne devraient pas se préoccuper de la diversification des revenus d'une banque dans la sélection des opportunités d'investissement car la diversification des revenus ne génère pas de performance financière positive.

EFFETTI DELLA DIVERSIFICAZIONE DEI REDDITI SULLA PERFORMANCE FINANZIARIA DELLE BANCHE COMMERCIALI ELICOTTE IN SIERRA LEONE
Lo scopo di questo studio era determinare l'effetto della diversificazione dei redditi sulla performance finanziaria delle banche commerciali in Sierra Leone. È stato adottato un disegno di ricerca descrittivo. È stato condotto un censimento mirato alle banche commerciali elencate in Sierra Leone dal 2018 al 2022. La significatività statistica di ciascuna variabile indipendente è stata testata eseguendo un test t al livello di significatività del 5%. La significatività del modello di regressione è stata testata eseguendo un test F al livello di significatività del 5%. Il potere esplicativo delle variabili indipendenti è stato valutato usando il coefficiente di determinazione, R^2. Lo studio ha scoperto che la diversificazione dei redditi era negativamente correlata alla performance finanziaria. I risultati del test t hanno indicato che l'effetto non era statisticamente significativo. Si è anche scoperto che la dimensione e l'adeguatezza di capitale avevano un effetto positivo, che era statisticamente significativo, mentre la liquidità aveva un impatto negativo sulla performance finanziaria e non era statisticamente significativa. Il coefficiente di determinazione per la regressione è stato trovato essere del 35,7%. Ciò implica che la variabile indipendente spiegava solo il 35,7% delle variazioni della variabile dipendente. Lo studio ha concluso che la diversificazione dei redditi è una questione costosa per le banche commerciali poiché ha un impatto negativo sulla performance finanziaria. Ha anche concluso che la dimensione e l'adeguatezza di capitale avevano un impatto positivo sulla performance finanziaria mentre la liquidità aveva un impatto negativo. Questo studio raccomanda che le banche commerciali non dovrebbero impegnare risorse per diversificare i loro redditi perché la diversificazione sembra essere una questione costosa. Inoltre, gli investitori non dovrebbero preoccuparsi della diversificazione dei redditi di una banca nella selezione delle opportunità di investimento poiché la diversificazione dei redditi non genera una performance finanziaria positiva.

El objetivo de este estudio fue determinar el efecto de la diversificación de ingresos en el rendimiento financiero de los bancos comerciales en Sierra Leona. Se adoptó un diseño de investigación descriptivo. Se realizó un censo dirigido a los bancos comerciales enumerados en Sierra Leona desde el año 2018 hasta el 2022. La significancia estadística de cada variable independiente se probó realizando una prueba t a un nivel de significancia del 5%. La significancia del modelo de regresión se probó realizando una prueba F a un nivel de significancia del 5%. El poder explicativo de las variables independientes se evaluó utilizando el coeficiente de determinación, R^2.
