The implied volatilities are prospective estimates which reflect future expectations about underlying asset volatility. The implied volatility can be seen as the market participants’ assessment of the uncertainty of the underlying asset. Implied volatilities are obtained by matching a set of market option prices with given strike price and time to maturity to those produced by Black-Scholes-Merton model (BSM model) using the same strike price and time to maturity. When the implied volatilities are plotted against various strike prices or different moneyness, one can obtain the implied volatility smile curve, while the pattern of implied volatilities across time to expiration is usually referred to as the term structure of implied volatilities.

a successful business is good knowledge of past and current trends, for the right long-term decisions to be made. According to Brealey et al. (2011), knowing where a company stands today is a necessary prelude to contemplating where the company might end up in the future. One of the options for supporting short-term and long-term decisions is financial analysis and financial ratios. Financial ratios have traditionally been indicators of a corporate’s overall performance (Rahman et al., 2017) and may help to quantify the potential impact of internal ratings on financial performance (Belas et al., 2012; Klieštik et al., 2020).

Sovereign credit rating (SCR) is an important utensil to judge the creditworthiness and competitiveness of an economy, which facilitates the potential investors to gain confidence in making investment decisions across the globe (Yang et al., 2019). It serves as a “credit passport” to investors to gain useful information about the financial markets in terms of dependable share prices, trim financial obstacles along with provocative effective
investment (Mclean et al., 2012; Xu et al., 2019; Zhao et al., 2020). Higher SCR signals a relatively higher performance of companies/ economies (Cubas-Díaz et al., 2018). The efficient market hypothesis holds that financial markets are sensitive to new information, where a piece of information is translated into security prices, depending upon the development of such markets.
the profitability of their company’s investments. They also encounter various types of costs – from the managerial perspective, these include paid taxes. Therefore, the management at multinational corporations takes advantage of the global digital economy and tries to plan tax liabilities in order to minimize them. Ignoring the opportunity to avoid taxes can result in a less competitive position. Tax planning has become an important tool for achieving better financial results. Within the global economy, the international aspect of tax planning is a key factor for multinational corporation management. The importance of tax burdens can also be seen in decision making on where to invest. Lower tax burdens can increase an investment’s profitability; therefore, managers incorporate rating tax legislation into their decision-making process for investment.

The debate on development of the bond market as major channel of industrial finance is gaining traction in many African economies. The secondary arm of the market, aside from the liquidity window it provides for investors in the primary market, additionally creates information linkage by fostering capital formation for prospective investors and producers that require capital to meet their investment opportunities, assisting in the allocation and operational efficiency of the capital market. Except if the market remains thin, overtime, liquidity in the market becomes more visible in the economy’s financial architecture, as it ignites market dynamism in the financial services linkage with other sectors of the economy. Liquidity is a pre-requisite to deepening the bond market, conditioned on information availability to ease asset valuation. The rapidity and randomness of information is what actually distinguishes capital market functionality and efficiency (Wijst, 2013).
