This study aims to provide empirical evidence on the impact of foreign share ownership on the liquidity of the Tunisian Stock Exchange (TSE).

Abstract

Purpose

This study aims to provide empirical evidence on the impact of foreign share ownership on the liquidity of the Tunisian Stock Exchange (TSE).

Design/methodology/approach

The authors hypothesize in the first strand that stock liquidity could be positively affected by foreign ownership based on the real friction channel. The authors then hypothesize in the second strand, based on the information friction channel, that foreign ownership's impact on stock liquidity could be insignificant or negative and that foreign investors raise the level of information asymmetry. A sample of 318 firm-year observations from Tunisia over the 2012–2017 period and a random-effects estimation were used. Moreover, using the 2SLS estimator, a robustness check framework was applied in order to address any potential reverse causality concerns.

Findings

The authors find strong evidence that higher foreign ownership improves stock liquidity. More specifically, firms with higher foreign ownership engender a lower bid-ask spread, a better stock ability to absorb a large amount of trading volume, and a larger depth. These findings are still valid when reverse causality concerns are addressed through the use of the 2SLS estimator.

Originality/value

The paper contributes to the existing literature by focusing on the ownership–liquidity relationship on a frontier market. It provides further empirical support that higher corporate governance quality reduces the information asymmetry problem and enhances stock market liquidity.

Abstract

Purpose

Using vector autoregressive modelling (VAR) and Granger causality tests, this paper attempts to empirically investigate the dynamic relationship between return and volume of transactions of two main cryptocurrencies: Bitcoin and Ethereum.

Design/methodology/approach

Based on a generalized autoregressive conditional heteroskedasticity (GARCH) model with a transaction volume parameter in the conditional volatility equation.

Findings

The results provide empirical evidence of a positive contemporaneous relationship between the variation in transaction volume and the daily return of Bitcoin and Ethereum. The results also show that the conditional volatility of the returns is affected by the past volatility, which implies weak-form inefficiency for both Bitcoin and Ethereum markets. The results of the VAR model, testing Granger causality, indicate that the volume of transactions Granger-Causes Bitcoin and Ethereum returns. Furthermore, the findings show a Granger causal relation from returns to volume.

Originality/value

This result suggests that cryptocurrency returns can predict transaction volumes and vice versa.

Abstract

Purpose

This article examines the link between the structure of the board of directors and target price accuracy using a sample of 51 listed firms on the Tunisian Stock Exchange over the period of 2011–2017.

Design/methodology/approach

In this study, the authors used the generalised method of moments (GMM) model to control the endogeneity problem.

Findings

As a result, that model can serve as a signal in the forecasting process. The authors' results suggest that target price accuracy is negatively related to board independence, and dual Chief Executive officer (CEO). In addition, CEO compensation tends to exert a negative impact on target price error.

Practical implications

The authors' findings are valuable for common investors because the findings can be useful in enhancing their capital allocation decisions by assigning higher weights to forecasts issued by firms with strong corporate governance systems. The authors' study also has practical implications for managers and policymakers. Specifically, the evidence provided herein suggests that firms with strong corporate governance mechanisms enhance the accuracy of market expectations, alleviate information asymmetry, and limit market surprises, especially in a context characterised by weak investor protection. The authors' results highlight the advantages of strong corporate governance in improving a firm's information environment and, therefore, are useful for the cost–benefit analysis of improving internal governance mechanisms. Additionally, the authors' results may prove useful to investors who can rely on the information provided by analysts for well-governed companies.

Social implications

The authors' study contributes to the literature in both corporate governance and analysts' forecasts fields. The study provides additional evidence of the benefit of board quality attributes on target price accuracy in an emerging market characterised by high information asymmetry and weak investor protection. The authors' findings exhibit the effectiveness of board attributes in producing better financial information quality in Tunisia. This is useful for investors who may improve their capital allocation decisions by assigning greater weights to target price forecasts of companies with good governance quality, suggesting that good corporate governance is a credible signal of better financial information quality. These results have important implications for capital market regulators and corporate management in encouraging the implementation of good governance practices.

Originality/value

The authors attempted to assess whether corporate governance of listed firms are priced in the Tunisian context characterised by weak governance control and to highlight which mechanism is highly considered by independent financial analysts to build their forecasts.
