The economic status of any nation is one of the factors that define its viability. A nation’s economic status refers to the extent to which its commercial activities make a way for the prosperity and satisfaction of the citizenry (Ubesie, Nwanekpe & Ejilibe, 2020). Naturally, all the nations of the world plan for and work towards the development of their economies, which are often diversified into various relevant sectors (Akinmulegun, 2018). Among these are the agricultural, trading, banking, transportation, science and technology, to mention a few. One veritable process of achieving and enhancing a thriving economy is via investment, which is expending one’s financial resources on a venture, after a reasoned consideration of the risks vis-à-vis the expected future returns, with the aim of creating and maximizing wealth (Persakis & Latridis, 2015). Share trading, the operations of which are managed by the capital market, is one major way by which investment into these various sectors can be executed. In other words, equity investment is key in economic growth process advancement and development. Equity also known as shares or stock, is defined as units of ownership which represents an equal proportion of a firm’s capital. The activity of financial systems plays significant and important decision in the development and economic expansion of organization. It is used in appraising the complexity of investment position of a nation specifically in attracting international investors. The capital market provides an avenue by which fund is often raised and channelized productively. It helps companies in financing existing and new projects, expand and develop commercial and industrial activities. A capital market a is credible avenue of long-term funds sourcing for economy development and is a developed economy leading economic indicator.
The capital market provides avenue for interaction and relationship between investors and savers for economic development and advancement. An efficient equity market will help to form an economy that is highly competitive and effective, without effective equity markets firms will need to depend upon internal financing via retained earnings. Large and successful firms are in better position in financing because they can finance their investment project through bank loan facilities and retain earnings without going through the scrutiny of the stock exchange, whereas new firms find it difficult to access adequate funds for their investment needs. Access to equity financing is very paramount for economic growth and development, to meet the needs of business activities expansion that is very crucial for economic advancement, well established and functioning share market is very important (Olure-Bank et al., 2015).
In the year 1960 Capital Market was founded in Nigeria, known as the Lagos stock market and in December 1977 it was converted to the Nigerian stock exchange (NSE), known presently as Nigerian Exchange Group. The operation started in 1961 along with 19 securities enlisted for the exchange. In the major cities of Nigeria, branches were established. The Nigerian stock market has 13 branches (without the top Lagos office). The NSE was consistently advancing to satisfy the needed requirements of the clients thereby succeed at the very best level of competitiveness. Nigeria Stock Market performs relatively, fairly transparently, and orderly markets which attract most enterprises in Africa, globally and investors in local communities. The Exchange is positioned to advocate for the acceleration of Africa’s economic growth and to become, gateway to African market.
Theoretical Review
Random walk Theory: The unpredictability motion and movements in futurity value of share prices underscore the random walk theory according to Burton (2012) the propounder of the theory in his book in 2012, in a market that conforms to the random walk theory, it is impossible to anticipate future prices using information about past prices (Worthington and Higgs, 2003). Hence, such returns in the market are uncorrelated serially, resembling a random walk hypothesis through pendent but uncorrelated accession, farther as they assert, may be autonomous but identically grouped or identically or independently redistributed.
The share value method based on fundamental analysis states that at any particular time according to the fundamental analytical method to asset value, at any given period, every share security has some value that are intrinsic which are based on some factors that are fundamental such as status of the business’s sector and return, quality of management, general economic outlook and rate of return on equity. Any change in of any of these variables lead to fluctuations in share values that could follow a predetermined practice
The subsistence of these frequently, suddenly and unexpectedly future share prices impacted by changes in the company’s fundamentals (Fama 1965), demonstrates that efficiency is still maintained through the share of market. The existence of these volatile share prices in the future, which (Fama,1965) attributes to shifting fundamental value demonstrates the effectiveness that share market, drawing a conclusion that actual cost of concluding the real security’s market price is always a reliable indicator of its intrinsic value, or the prices of the securities, at any particular time and security actually fluctuate arbitrarily in relation to their underlying values.
Efficient Market Theory: According to the efficient market theory by (Fama, 1965) share market value (price) reflects all available information and shares are traded always at the fair value on exchange. Marketing of share becomes difficult for investors to sell shares for inflated price or purchase undervalued shares and investor can only have higher returns by purchasing riskier investment. Market can be more efficient as more participants are engaged in a market, market will be more efficient as more people transact, compete supply more and various forms of information relating to the market value of shares (price), as markets becomes more liquid and active, possibility of arbitrageur may also emerge, more profiting by correcting small inefficiencies whenever it arises and restoring efficiency quality.
There are some markets that are less efficient than another. Inefficient market is the market in which prices of assets do not accurately reflect its true market value which may be due to several reasons which may include information asymmetries, inadequate of buyers and sellers, low liquidity, human opinion, high transaction cost, human emotions, market psychology, among other reasons. The stock market’s effectiveness in using information is explained by the theory. The Efficient Market Theory (EMT) could be employed to further explain the fundamental class of stock market information in connection with their responsiveness to share prices (Uthman et al., 2014).
When the share price reflects all of the available information, the capital market is regarded as strong. It signifies that the share price can reveal all information material and significant to the firm, it entails the theory of a semi-strong efficient market and absolutely the entire information accessible to the company insider which may include the manager or financial experts of the firm traded publicly. Market is tagged semi-strong when the entire available information in public is noticeable in the stock price, it entails former price that is included in weak form efficient market theory, also other information that can influence market price value that are publicly accessible such as fundamental information on the firm’s product, management quality, statement of financial positions content, accounting practice and earnings forecast.
While market could be referred to as weak, when stock prices include all available information, rather than just past data relating to share price can be gotten by reviewing market trade information such as historical prices from the past, interest, and trading volume.
In the semi-strong economy, financial information thrives considerably, so far it serves as the fundamental source of information shared with the public through the release of financial reports (ICAN, 2019). Cunningham (2005) pessimistically asserted that any endeavor to upgrade accounting theory and practice is futile since the share price is quickly decoupled from historical accounting data. The hypothesis that accounting information is mostly preferred for predicting share prices has been somewhat strengthened by this analysis.
Therefore, considering that share value reflects accounting records, investors are anticipated to promptly decide whether to trade or keep onto their available investment based on changes in the share price, having taken the information into consideration if it is favourable or not (ICAN, 2019). Furthermore, accounting systems frequently have unintended effects on decisions, and industry participants are more likely to react to apparent changes than that to aggregate output.
Positive Accounting Theory : Watts and Zimmerman propounded the positive accounting theory. According to positive accounting theory, historical development arisen in the first stages, provide financial information drawing on the customary rules to particular activity beneficiary. Analytic rationales in the form of a bloc of broad comprehensive and fundamental laws and assumptions that furnishes a frame of general reference by which evaluation and guidance of accounting practice can assist in development of new procedures and practices are referred to as accounting theory (Hendriksen 1982) and (Hassan & Talal ,2015).
Indeed, an increasing concern has been on economic effects of the stock market development. The metric of business direction usually said to be measured by the capital market, due to the benefit it gives the business organizations and economy, thus making it the center of concentration for investors and policymakers. Growth of share and capital market allow the government to arrange long term capital financing for economic growth and providing adequate information for appraisement (Oyedokun & Ajose, 2018). The stock exchange market development’s role in global stock exchanges hinged on the effective exchange exerted on the economy.
Economic sectors attract savings from various households and disbursed them efficiently to various entrepreneurs and unproductive spending will be reduced and capital market only finances viable project, the stock market either directly or indirectly contribute to the economic development process. One of the main functions of the market are the creation of liquidity, mobilization of savings, risk diversification, acquisition of data, improve dissemination, and enhancement of incentives for corporate controls. The speed of the economic process will be successively increased by quick service delivery and also will increase the efficiency and effectiveness of those operations (Cordella, 2019).
Empirical Review
Nwidobie (2014) carried out research on the financial situation and performance with the aid of the Augmented Dickey Fuller (ADF) test, the researcher analyses (API) All Price-Index data of shares of quoted companies on Nigeria Exchange Group covering a period between Januarys to December 2012. The findings show that price of share movement did not follow the random walk theory on the Nigeria Exchange Group. The findings of the research indicate the subsistence of market inefficiency in the capital market in Nigeria, requiring the flow of free and cheap information on seemly fundamental into share pricing market by the forces of supply and demand.
Tijjani et al (2019) conducted a study on equity investment appraisement by Nigeria investors. Semi-structure interview was conducted with investors and stockbrokers.
