This study examines the relationship between Working Capital Management Firm Liquidity and Stock Market Seasonality among quoted firms in Nigeria. Six hypotheses were formulated following the dependent variable of Stock Market Liquidity. The independent variables employed for this study include: Liquidity Ratio, Account Payable Day, Account Receivable Day, Inventory Day, Firm Leverage and Firm Size. This study is based on ex-post facto research design and employed a panel data set collected Fifty (50) non-financial companies over an eight year period ranging from 2011 to 2018 financial year. We analyzed the data set using descriptive statistics, correlation and Panel Ordinary Least Square Regression Analysis. Our finding lends credence to the efficient market theory which holds that share markets prices are unpredictable and as such cannot be forecasted. Specifically, the finding suggests that market liquidity cannot predict stock market returns irrespective of the season of the year. Hence, we carefully hold that the stock market in Nigeria is efficient due to its randomness and will rapidly respond to any information or anomalies presented to it. The study recommends among others that policy makers in emerging markets such as Nigeria should ease entry barriers for prospective firms so as to enhance liquidity. The study further recommends that, proper inventory management system should be put in place in order to avoid working capital mismanagement.
