Purpose This paper aims to clarify the mechanism by which heuristics influences the investment decisions of individual investors, actively trading on the Pakistan Stock Exchange (PSX), and the perceived efficiency of the market. Most studies focus on well-developed financial markets and very little is known about investors’ behaviour in less developed financial markets or emerging markets. The present study contributes to filling this gap in the literature. Design/methodology/approach Investors’ heuristic biases have been measured using a questionnaire, containing numerous items, including indicators of speculators, investment decisions and perceived market efficiency variables. The sample consists of 143 investors trading on the PSX. A convenient, purposively sampling technique was used for data collection. To examine the relationship between heuristic biases, investment decisions and perceived market efficiency, hypotheses were tested by using correlation and regression analysis. Findings The paper provides empirical insights into the relationship of heuristic biases, investment decisions and perceived market efficiency. The results suggest that heuristic biases (overconfidence, representativeness, availability and anchoring) have a markedly negative impact on investment decisions made by individual investors actively trading on the PSX and on perceived market efficiency. Research limitations/implications The primary limitation of the empirical review is the tiny size of the sample. A larger sample would have given more trustworthy results and could have empowered a more extensive scope of investigation. Practical implications The paper encourages investors to avoid relying on heuristics or their feelings when making investments. It provides awareness and understanding of heuristic biases in investment management, which could be very useful for decision makers and professionals in financial institutions, such as portfolio managers and traders in commercial banks, investment banks and mutual funds. This paper helps investors to select better investment tools and avoid repeating expensive errors, which occur due to heuristic biases. They can improve their performance by recognizing their biases and errors of judgment, to which we are all prone, resulting in a more efficient market. So, it is necessary to focus on a specific investment strategy to control “mental mistakes” by investors, due to heuristic biases. Originality/value The current study is the first of its kind, focusing on the link between heuristics, individual investment decisions and perceived market efficiency within the specific context of Pakistan.

PurposeThis paper aims to show how overconfidence influences the decisions and performance of individual investors trading on the Pakistan Stock Exchange (PSX), with the mediating role of risk perception and moderating role of financial literacy.Design/methodology/approachThe deductive approach was used, as the research is based on the theoretical framework of behavioural finance. A questionnaire and cross-sectional design were employed for data collection from the sample of 183 individual investors trading on the PSX. Hypotheses were tested through correlation and regression analysis. The Baron and Kenny method was used to test the mediation effect of risk perception and the moderation effect of financial literacy. The results of mediation and moderation were also authenticated through the PROCESS and structural equation modelling (SEM) technique.FindingsThe results suggest that risk perception fully mediates the relationships between the overconfidence heuristic on the one hand, and investment decisions and performance on the other. At the same time, financial literacy appears to moderate these relationships. The results suggest that overconfidence can impair the quality of investment decisions and performance, while financial literacy and risk perception can improve their quality.Practical implicationsThe paper encourages investors to base decisions on their financial capability and experience levels and to avoid relying on heuristics or their sentiments when making investments. It provides awareness and understanding of heuristic biases in investment management, which could be very useful for decision makers and professionals in financial institutions, such as portfolio managers and traders in commercial banks, investment banks and mutual funds. This paper helps investors to select better investment tools and avoid repeating the expensive errors that occur due to heuristic biases. They can improve their performance by recognizing their biases and errors of judgment, to which we are all prone, resulting in better investment decisions and a more efficient market. The paper also highlights the importance on relying on professional knowledge, giving it greater weight than feelings and biases.Originality/valueThe current study is the first to focus on links between overconfidence, financial literacy, risk perception and individual investors' decisions and performance. This article enhanced the understanding of the role that heuristic-driven bias plays in the investment management, and more importantly, it went some way towards enhancing understanding of behavioural aspects and their influence on the investment decision-making and performance in an emerging market. It also adds to the literature in the area of behavioural finance specifically the role of heuristics in investment strategies; this field is in its initial stage, even in developed countries, while, in developing countries, little work has been done.

Purpose This paper aims to investigate the effects of entrepreneurial orientation (EO) on the performance of small and medium-sized enterprises (SMEs) with mediating role of differentiation strategy in Pakistan. Design/methodology/approach A theoretical framework has been developed to base the hypotheses, as also to determine the exact approach in this study. To establish the influence of EO on the performance of SME, a five-point Likert scale questionnaire has been used to collect data from middle and senior managers who operate in SMEs in the manufacturing sectors. The sample illustrates 166 incumbents, comprising 68.07 per cent from middle management and 31.93 per cent from senior management operating in manufacturing sector of SMEs, by means of a stratified random sampling technique. The collected data were analyzed using SPSS and Amos graphics software. Hypotheses were tested by using structural equation modeling (SEM) technique. Findings EO, as a whole, presents a significant positive effect on the performance of SMEs. Moreover, differentiation strategy partially mediated the relationship between EO and performance of SMEs. Two dimensions of EO, proactiveness and risk-taking propensity, strongly increased firm performance while innovativeness, competitive aggressiveness, autonomy and competitive energy did not cause any significant change. The findings differ from the current view of western enterprises that innovativeness (INO) played a major role by increasing performance of SMEs. The results transpired that innovativeness (INO) tends to reduce performance of SMEs, but the p-value did not reach a high significance value. Research limitations/implications The main limitation of this empirical study is comparatively a small size of the sample. The analysis of power suggests that a larger sample could have provided more reliable and extensive results. Regardless of that, the analysis of reliability, using the Cronbach's alpha, exhibited the consistency of outcomes in providing an accurate portrait of the EO influences on the performance of SME. Practical implications The study verifies that two dimensions of EO have considerable effects on the performance of SMEs, while the others have not, whereas, the EO, as whole, has significant positive effect on performance of SMEs. These findings should be helpful for researchers looking for appropriate performance measures, and for entrepreneurs aiming at getting support for their decisions and evaluating their performance. Originality/value The current study appears to be first of its kind focusing on the link between EOs, as whole, and its dimensions, to performance of SMEs and differentiation strategies within the specific context of Pakistan.

PurposeThe purpose of this article is to clarify the mechanism by which underconfidence heuristic-driven bias influences the short-term and long-term investment decisions of individual investors, actively trading on the Pakistan Stock Exchange.Design/methodology/approachInvestors' underconfidence has been measured using a questionnaire, comprising numerous items, including indicators of short-term and long-term investment decision. In order to establish the influence of underconfidence on the investment decisions in both the short and long run, a 5-point Likert scale questionnaire has been used to collect data from the sample of 203 investors. The collected data were analyzed using SPSS and AMOS graphics software. Hypotheses were tested using structural equation modeling technique.FindingsThis article provides further empirical insights into the relationship between heuristic-driven biases and investment decision-making in the short and long run. The results suggest that underconfidence bias has a markedly negative influence on the short-term and long-term decisions made by investors in developing markets. It means that heuristic-driven biases can impair the quality of both short-term and long-term investment decisions.Practical implicationsThis article encourages investors to avoid relying on cognitive heuristics, namely, underconfidence or their feelings when making short-term and long-term investment strategies. It provides awareness and understanding of heuristic-driven biases in investment management, which could be very useful for finance practitioners' such as investor who plays at the stock exchange, a portfolio manager, a financial strategist/advisor in an investment firm, a financial planner, an investment banker, a trader/broker at the stock exchange or a financial analyst. But most importantly, the term also includes all those persons who manage corporate entities and are responsible for making its financial management strategies. They can improve the quality of their decision-making by recognizing their behavioral biases and errors of judgment, to which we are all prone, resulting in more appropriate investment strategies.Originality/valueThe current study is the first to focus on links between underconfidence bias and short-term and long-term investment decision-making. This article enhanced the understanding of the role that heuristic-driven bias plays in the investment management and more importantly, it went some way toward enhancing understanding of behavioral aspects and their influence on the investment decision-making in an emerging market. It also adds to the literature in the area of behavioral finance specifically the role of heuristics in investment strategies; this field is in its initial stage, even in developed countries, while, in developing countries, little work has been done.

PurposeThis study aims to explore the mechanism by which intellectual capital and corporate social responsibility (CSR) influence the sustainable competitive performance of small and medium-sized enterprises (SMEs), with the mediating role of organizational innovation in an emerging economy.Design/methodology/approachThe data collection was conducted through a survey completed by 208 owners and top managers operating in the service, trading and manufacturing sector SMEs, positioned within twin cities of Pakistan. Structural equation modeling (SEM) was utilized for data analysis.FindingsThe results of the study suggest that intellectual capital and CSR have a markedly positive influence on the sustainable competitive performance of SMEs. The organizational innovation appears to mediate these relationships.Originality/valueThis study pioneers research on the links between intellectual capital, CSR organizational innovation and sustainable competitive performance of SMEs. The current research contributes to the literature by defining intellectual capital and CSR as an antecedent and organizational innovation as an intervening variable for the sustainable competitive performance of SMEs. In addition, this study underlines the significance of intellectual capital and CSR activities as valuable intangible assets for the achievement of sustainable competitive performance of SMEs.
