Doctor Jekyll and Mr. Hyde: Stress Testing of Investor Behavior
No full textBased on the results of a questionnaire submitted to 3,000 people, this paper traces the concrete effects of cognitive bias on the choices of stock market investors. Data on the flow of sales and purchases on the Italian stock market are used to quantify the behavioral costs implicit in prospect theory. The same data highlight the different attitudes of investors in the two recent economic crises of 2001 – 2002 and 2008 – 2009. The data is interpreted in a manner coherent with the theory supporting a shift from risk aversion to risk propensity under certain specific circumstances. Finally, several simulations carried out on the basis of Robert Shiller’s Confidence Indexes show that investors do not have a particular problem in perceiving market irrationality, and reach conclusions that are broadly correct in terms of assessing price versus value. Nevertheless, investors have trouble making financially sound choices when information on price prevails and becomes more available – and thus more real – than other informatio
Herding in Imperial Russia: Evidence from the St. Petersburg Stock Exchange (1865–1914)
No full textWe present seminal empirical evidence on market-wide herding from historical markets for the St. Petersburg stock exchange between 1865 and 1914. Our findings indicate the presence of herding in Imperial Russia’s largest equity market, which tends to vary among industries and grow stronger during months of negative performance and declining volatility. Controlling for the 1893-reform that prompted wider social participation in equity trading, we find that herding surfaces exclusively in the post-reform years, with no evidence of herding arising pre-reform. Our results showcase that the behavior of investors in historical stock exchanges exhibits patterns similar to those of modern-day ones

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Premiums, Discounts and Feedback Trading: Evidence from Emerging Markets' ETFs
No full textThis study investigates the extent to which ETFs' premiums and discounts motivate feedback trading in emerging markets' ETFs. Using a sample of the first-ever launched broad-index ETFs from four emerging markets (Brazil, India, South Africa and South Korea), we produce evidence denoting that feedback trading grows in significance in the presence of lagged premiums. The significance of feedback trading becomes more widespread across our sample's ETFs as the lagged premiums grow in magnitude, with evidence also suggesting that the effect of lagged premiums over feedback trading varies prior to and after the outbreak of the recent global financial crisis
Do Fund Managers Herd in Frontier Markets – and Why?
No full textFrontier markets constitute a category of markets for which very little is known regarding the behaviour of their institutional investors. This study attempts to shed light on this issue by investigating whether fund managers herd in frontier markets and whether their herding is intentional or not using data on quarterly portfolio holdings of funds from two such markets (Bulgaria and Montenegro). Results show that fund managers herd significantly in both markets; controlling for the interaction of their herding with different market states, we find that herding is stronger for both markets during periods of positive market performance and high volume, while in the case of Montenegro it also appears significant during periods of low volatility. Our findings are consistent with fund managers herding intentionally, in anticipation of informational and/or professional payoffs. We also find that Bulgarian (Montenegrin) fund managers herd significantly after (before) the outbreak of the 2008 global financial crisis and we attribute this to a volume-effect, since Montenegro (Bulgaria) saw the heaviest trading activity before (after) the crisis' outbreak
Does mood affect institutional herding?
No full textDrawing on a unique data set of daily portfolio holdings for Turkish mutual funds we investigate the relationship between mood and institutional herding on the premises of various established mood proxies (weekend effect; holiday effect; Ramadan; sunshine). Results indicate that fund managers in Turkey herd significantly, with their herding growing in magnitude as the number of active funds per stock rises and appearing stronger on the buy- than the sell-side. Although the relationship of mood with institutional herding occasionally assumes the correct sign as per theoretical expectations, institutional herding is found to be insignificantly different across various mood states, thus denoting that mood does not impact the propensity of fund managers to herd
