PurposeThe objective of this paper is to explore how anchoring affects the dynamics of investor decision-making with regard to mutual funds and how this bias differs amongst gender and level of financial knowledge.Design/methodology/approachAn experimental research design was adopted to uncover the relationship between the variables under study; this involved the use of a questionnaire with an embedded experiment. Data obtained from the study were analysed using Pearson's chi-square test and two-way analysis of variance.FindingsThe findings show that, overall, investors were prone to be significantly influenced by the anchoring bias. The study finds a strong, albeit not significant, association between participants' susceptibility to anchor and both gender and the level of financial knowledge of participants. Females were observed to be more likely to anchor than their male counterparts. Also, a higher level of financial knowledge did not help to reduce the possibility of anchoring; it rather increased it.Research limitations/implicationsThe findings of the study cannot be interpreted as suggesting causality as the study only tests for association between variables and not causality. Additionally, external validity cannot be fully established as a result of the quasi-experiment approach used.Practical implicationsThe study adds to the body of knowledge on the influences of behavioural biases in the sub-region to make investors aware of their biases in order to minimise the influence of these biases on their investment decisions.Originality/valueThis study differs from earlier studies in that it analyses the presence of anchoring as influenced by a completely different set of variables (expertise and gender) and also does it within the context of an African country where there remains a paucity of research on behavioural finance.

PurposeAlthough some research has been carried out on feedback trading in different asset classes, there have been few empirical investigations that consider both major and emerging stock markets (Koutmos, 1997; Antoniou et al., 2005; Kim, 2009) stock index futures (Salm and Schuppli, 2010). In this study, the author examines positive/negative feedback trading in both developed-emerging-frontier-standalone (51) stock markets for 2010–2020 and sub-periods including COVID-19 period.Design/methodology/approachThe hypothesis “feedback trading behaviour led the price boom/bust in the stock markets during the first quarter of COVID-19 pandemic” is tested by employing the Sentana and Wadhwani (1992) framework and using asymmetrical GARCH models (GJRGARCH, EGARCH) in accordance with the empirical literature.FindingsThe following conclusions can be drawn from the present study; (1) There is no evidence to support a significant distinction between developed, emerging, frontier or standalone markets or high/upper middle, lower middle income economies in the case of feedback trading. It is more likely to be a general phenomenon reflecting the outcomes of general human psychology (2) in the long term (2010–2020) based on the feedback trading results Asian stock markets appear to be far from efficiency.Research limitations/implicationsStock markets are selected based on data availability.Practical implicationsSeveral inferences can be drawn about overall results. First, investors and portfolio managers should beware of their investment decisions during bearish market conditions where volatility is on the rise and also when there is a strong reaction to bad news/negative shocks in the market. Moreover, investing in Asia stock markets may require more attention since those markets are reputed to be more “idiosyncratic”, less reliant on economic and corporate fundamentals in their pricing. Moreover, the impact of foreign investors on stock market volatility and returns and weaker implementation of regulations also affect the efficiency of the markets (Lipinsky and Ong, 2014).Originality/valueTo the best of the author’s knowledge, most studies in the field of feedback trading in stock markets have only focused on a small sample of countries and second, the effect of COVID-19 uncertainty on the stock markets have not been addressed in the literature with respect to feedback trading. This paper fills these literature gaps. This study is expected to provide useful insights for understanding the instabilities in stock markets particularly under conditions of high uncertainty and to fill the gap in the literature by comparing the results for a large sample of countries both in the long term and in the pandemic.Highlights for reviewThis study has shown that feedback trading is more prevalent in Asian stock markets in the long run in Europe, America or Middle East for the period 2010–2020.Positive feedback traders generally dominated most of the stock markets during the
虽然对不同资产类别的反馈交易进行了一些研究，但很少有实证调查同时考虑主要和新兴股票市场(Koutmos, 1997;Antoniou等人，2005;股指期货(Salm and Schuppli, 2010)。在本研究中，作者考察了2010-2020年发达-新兴-前沿独立(51)股票市场和包括COVID-19在内的子时期的正/负反馈交易。设计/方法/方法采用Sentana和Wadhwani(1992)框架，并根据实证文献使用不对称GARCH模型(GJRGARCH, EGARCH)，对“反馈交易行为导致COVID-19大流行第一季度股票市场价格暴涨/暴跌”这一假设进行了检验。从本研究中可以得出以下结论:(1)在反馈交易的情况下，没有证据支持发达市场、新兴市场、前沿市场或独立市场或高/中上收入经济体、中低收入经济体之间存在显著区别。从反馈交易结果来看，这更可能是一种反映长期(2010-2020)人类普遍心理(2)结果的普遍现象。研究的局限性/意义股票市场的选择是基于数据的可用性。实际意义总的结果可以得出几个推论。首先，投资者和投资组合经理应该注意他们在市场波动率上升的熊市条件下的投资决策，以及当市场对坏消息/负面冲击有强烈反应时。此外，投资亚洲股市可能需要更多关注，因为这些市场被认为更为“特殊”，在定价方面较少依赖于经济和企业基本面。此外，外国投资者对股票市场波动和回报的影响以及监管执行不力也影响了市场的效率(Lipinsky和Ong, 2014)。原创性/价值据作者所知，股票市场反馈交易领域的大多数研究仅关注于国家的小样本，其次，关于反馈交易的文献中尚未解决COVID-19不确定性对股票市场的影响。本文填补了这些文献空白。预计这项研究将为理解股票市场的不稳定性，特别是在高度不确定性条件下的不稳定性提供有用的见解，并通过比较大量国家样本在长期和大流行期间的结果来填补文献中的空白。本研究表明，从长远来看，反馈交易在2010-2020年期间在欧洲、美国或中东的亚洲股票市场更为普遍。在COVID-19大流行初期，正反馈交易者普遍主导了大多数股票市场。另一个重要发现是，马来西亚、日本、菲律宾、爱沙尼亚、葡萄牙和乌克兰的股票市场由负面反馈交易者主导，这可能被解释为“处置效应”，即他们出售“过去的赢家”。在印度尼西亚、新西兰、中国、奥地利、希腊、英国、芬兰、西班牙、冰岛、挪威、瑞士、波兰、土耳其、智利和阿根廷，即使在不确定的条件下，也不存在正反馈和负反馈交易。

PurposeThis paper examines the effect of the holy month of Ramadan on the returns and conditional volatility of cryptocurrency markets.Design/methodology/approachThe closing prices of six cryptocurrencies have been considered. The study employs different classical tests for checking if the efficiency behaviour is similar during Ramadan celebration days and non-Ramadan days. Besides, dummy variable regression technique for assessing this anomaly on returns and volatilities has been applied.FindingsAlthough no significant effect on returns and volatility for Litecoin has been found, the results provide evidence about the existence of the Ramadan effects in cryptocurrency markets. The results of the mean equations show the existence of Ramadan effect for Ethereum, Ripple, Stellar and BinanceCoin for all considered models. Significant effect on Bitcoin returns is found with an autoregressive model of order 1. The results of conditional volatility show Ramadan effect on volatility is not detected.Originality/valueFirst, a new contribution in the incipient study of cryptocurrency analysis. Second, a comprehensive review of recently published empirical articles about Ramadan effect on traditional assets has been carried out. Third, unlike most of the papers focussed on the study of Bitcoin, this study has been extended to six cryptocurrencies. Ramadan effect have not been analysed in cryptomarkets yet. This study come to fill this gap and analyses Ramadan effect, previously documented for traditional assets, in particular, stock index from Muslim countries, but not yet analysed in the cryptocurrency markets.

PurposePredatory trading is a stock market trading technique in which certain market participants exploit information about other market participants' need to trade. Predatory trading often harms others. Hence, this paper examines the determinants and effects of financial practitioners' and lay people's judgments of predatory trading. Specifically, it investigates how the public availability and reliability of the exploited information affect their ethics and legality judgments and how the latter influence their behavioral intentions and regulation support.Design/methodology/approachThe authors conducted two scenario judgment studies. In the first study, participants were financial practitioners, and in the second – lay people.FindingsPractitioners often judge predatory trading to be ethical. Practitioners and lay people incorporate in their ethics and legality judgments the public availability of the exploited information but tend to discount the legal reliability criterion. Lay people justify their ethics judgments using harm, legal or profit maximization principles. Practitioners' intentions to engage in predatory trading and lay people's intentions to let predatory fund managers invest their money depend on their judgments, which influence their regulation support.Originality/valueThis paper is the first to explore people's judgments of predatory trading. It highlights that despite the harm that predatory trading involves, practitioners often judge it to be ethical. Although law tends to lag behind financial innovation, people base their judgments and hence also behavioral intentions on their interpretation of the regulation. Hence, it reveals a dark aspect of the relationship between ethics and legality judgments.

Purpose Research has suggested that ethics judgments should be made from an impartial perspective. However, people are often partial about their money. This study aims to investigate the extent to which perspectives – the perspective of those who can gain from the use of a financial practice and the perspective of those who can incur losses due to it – affect lay people’s ethics and legality judgments of the practice. In addition, it asks which factors influence their investment intentions.Design/methodology/approach The study uses a between-participant scenario experiment, in which participants are presented with cases of predatory trading and front running. Each participant is asked to take either a gain or loss perspective through the formulation of the presented cases. Subsequently, all participants make ethics, legality and investment intention judgments.Findings The authors establish that perspectives significantly affect people’s ethics judgments and, to a lesser extent, their legality judgments. People’s investment intentions depend on their perspectives, too, as well as on their financial considerations, ethics judgments, legality judgments and trust.Originality/value Research has focused on relatively stable determinants of people’s ethics judgments of financial practices. This paper shows that the situational prospect of profit can sway lay people’s judgments. When people take the gain perspective, they judge financial practices to be more ethical than when they take the loss perspective. Furthermore, people’s perspectives can distort their legality judgments and influence their investment intentions.

PurposeThe paper provides new evidence for Bitcoin’s safe-haven property by examining the relationship between currency price, return and Bitcoin trading volume.Design/methodology/approachA unique dataset from a person-to-person (p2p) exchange is used to investigate association between Bitcoin trading volume and currency prices. Currency returns are used to identify local economic crises, the 8 crisis affected currencies are Venezuela Bolivar (VES), Iranian Rial (IRR), Ukrainian Hryvnia (UAH), Argentine Peso (ARS), Egyptian Pound (EGP), Nigerian Naira (NGN), Turkish Lira (TRY) and Kazakhstani Tenge (KZT).FindingsThe paper demonstrates that local economic crises are positively associated with increased Bitcoin trading. There is a negative association between trading volume and currency value (and return), suggesting low currency price and currency depreciation are accompanied with increased Bitcoin trading. The results not only hold for the crisis affected currencies but also currencies of advanced economies. Granger causality test also reinforces the negative association results.Originality/valueThe finding indicates some forms of flight-to-safety have occurred during local market crises when capital flight from domestic markets to Bitcoin, strengthening Bitcoin’s hedging asset status. However, total global trading volume declines after the start of the COVID pandemic, suggesting that Bitcoin is still regarded as a speculative asset. Overall, the findings show that Bitcoin is a hedging asset to protect against local currency depreciation, but not a safe-haven asset for the global crisis.

PurposePrevious literature shows that market sentiment and the steepness of index option's implied volatility slope have a negative relation. This paper investigates the relation between firm-specific sentiment and individual option's implied volatility slope both theoretically and empirically.Design/methodology/approachThe authors develop a simple model with option traders' sentiment heterogeneity to show that sentiment and the steepness of individual option's implied volatility slope have a positive relation.FindingsWhen firm-specific sentiment is higher (more bullish), individual option's implied volatility slope becomes steeper. The positive relation is stronger when option traders' beliefs on risk are more dispersed. Empirical results support the theoretical model predictions.Originality/valueAlthough both firm-specific sentiment and individual options implied volatility slope predict future stock returns, there is no research exploring the relation between them. In particular, none of previous studies associates implied volatility slope's stock return predictability to investor behavior such as sentiment. The authors’ findings provide a behavior-based explanation on why steep implied volatility slope negatively predicts cross-sectional stock returns.

PurposeHow did investors in the Swedish Premium Pension System (PPS) react to the stock market shock ignited by the COVID-19 pandemic?Design/methodology/approachThe authors use fund-level data from the Swedish Pensions Agency on investment choices in the PPS. For each fund, the authors use monthly information on the number of investors and holdings' market value up to November 2020. The authors also use information on the total number of portfolio changes per day. For analyzing whether PPS investors reacted to the pandemic with claiming their pension, the authors use monthly data on the number of investors of a certain age group who initiate their public pension payment.FindingsTrades more than doubled, and shifted capital from equity funds to low risk interest funds. In economic terms, however, trading stayed at low levels–less than two percent of investors traded in March 2020 and there was no effect on pension withdrawals. The increased trading during the market tumult was disproportionately concentrated among investors in the top of the pension capital distribution.Research limitations/implicationsWith fund-level data, the authors cannot investigate what in particular made retirement investors stay calm in the midst of a severe market decline. Either, those investors have a long-term investment horizon as they save for their pension or particular features of the system's choice architecture induce inertia and discourage from trading. The sub-group analyses are more consistent with the explanation that PPS-induced inertia is responsible for the relatively small increase in trading activity, but future research could exploit individual level data to explore this in more detail.Practical implicationsThe often-criticized PPS choice architecture provided positive side effects in times of a severe market shock by shielding retail investors from committing trading mistakes when trying to outsmart the market.Originality/valueThe study complements previous evidence on the effects of COVID-19 on investor activity. The small response of PPS investors to COVID-19 is in line with earlier US findings on 401(k) accounts during the 2007 financial crisis (Tang et al., 2012) and industry reports about the COVID-19 period (see, e.g. Mitchell, 2020). The authors find no effects at all on public pension withdrawals in Sweden, while evidence from US 401(k) plans indicates a small share of workers taking COVID-related early withdrawals.
{"title":"Trading behavior of Swedish retirement investors during the COVID-19 pandemic","authors":"Johannes Hagen, Amedeus Malisa, Thomas Post","doi":"10.1108/rbf-09-2021-0183","DOIUrl":"https://doi.org/10.1108/rbf-09-2021-0183","url":null,"abstract":"PurposeHow did investors in the Swedish Premium Pension System (PPS) react to the stock market shock ignited by the COVID-19 pandemic?Design/methodology/approachThe authors use fund-level data from the Swedish Pensions Agency on investment choices in the PPS. For each fund, the authors use monthly information on the number of investors and holdings' market value up to November 2020. The authors also use information on the total number of portfolio changes per day. For analyzing whether PPS investors reacted to the pandemic with claiming their pension, the authors use monthly data on the number of investors of a certain age group who initiate their public pension payment.FindingsTrades more than doubled, and shifted capital from equity funds to low risk interest funds. In economic terms, however, trading stayed at low levels–less than two percent of investors traded in March 2020 and there was no effect on pension withdrawals. The increased trading during the market tumult was disproportionately concentrated among investors in the top of the pension capital distribution.Research limitations/implicationsWith fund-level data, the authors cannot investigate what in particular made retirement investors stay calm in the midst of a severe market decline.

PurposeThis study aims to examine individuals' tendency to strictly follow their own signal while ignoring predecessors' decisions when making decisions under varying degrees of uncertainty.Design/methodology/approachUsing a controlled laboratory experiment, the authors separate the follow-own-signal behavior from other types of behavior such as Bayes consistent or herd-like (i.e. follow-the-majority) behavior.FindingsAs the authors systemically increase the degree of uncertainty in the information environment, participants are increasingly more likely to act only on their own signal. This suggests that financial decisions that are made under highly uncertain market conditions may be more signal revealing, and hence, may lead to better information aggregation than previously thought. The authors also find that as uncertainty increases, participants are more likely to switch in and out of this behavior, suggesting that behavior under highly uncertain conditions may also be more random and complex.Originality/valueThe authors are the first to examine how uncertainty affects the follow-own-signal behavior. The authors also offer potential testable empirical implications, such as an increase in contrarian investing, home bias, and own-company ownership under times of increased uncertainty or in more uncertain markets.

PurposeThis article examines the accuracy and bias inherent in the wisdom of crowd effect. The purpose is to clarify what kind of bias crowds have when they make predictions. In the theoretical inquiry, the effect of the accumulated absolute deviation was simulated. In the empirical study, the observed biases were examined using data from forecasting foreign exchange rates.Design/methodology/approachIn the theoretical inquiry, the effect of the accumulated absolute deviation was simulated based on mathematical propositions. In the empirical study, the data from 2004 to 2011 were provided by Nikkei, which holds the “Nikkei Yen Derby” competition. In total, 3,657 groups forecasted the foreign exchange rate, and the first prediction was done in early May to forecast the rate at the end of May. The second round took place in June in a similar manner.FindingsThe average absolute deviation in May was smaller than that in June. The first round of prediction was more accurate than the second round one. Predictors were affected by the observable real exchange rate, such that they modified their forecasts by referring to the actual data in early June. An actuality bias existed when the participants lost their diverse prospects. Since the standard deviations of the June forecasts were smaller than those of May, the fact-convergence effect was supported.Originality/valueThis article reports novel findings that affect the wisdom of crowd effect—referred to as actuality bias and fact-convergence effect. The former refers to a forecasting bias toward the observable rate near the forecasting date. The latter implies that predictors, as a whole, indicate smaller forecast deviations by observing the realized foreign exchange rate.
