The Monday effect, in which returns and trading volumes on Mondays are generally lower than other days of the week, is one of the anomalies of the EMH. Researchers postulated the different investment patterns of individual investors as an explanation for the Monday effect. The purpose of this comparative study is to examine the role of individual investors on the Monday effect in the United States stock market. This study involved using actual individual investor data from the New York Stock Exchange from May 2006 to April 2016. The study design is based on a non-experimental, quantitative, and comparative design and builds upon Fama’s EMH theory. The focus is to compare investors’ average daily returns, individual investor average daily trade percentages, and trading patterns on Monday with other weekdays. Using results from one-way ANOVA, study results demonstrated day of the week was not a factor in terms of average daily returns and individual investor daily trade percentages on Monday did not significantly differ from those on Tuesday, Wednesday, and Thursday. However, the percentage of individual investor trades on Fridays was significantly lower than individual investor trades on other weekdays. Days of the week had no effect on individual investor trading patterns. Results of this study may lead to positive social change by understanding individual investor trading behaviors, reducing information asymmetry, and increasing stock market liquidity.

They require interest payments only prior to maturity. Since 3% is obviously below market, what is the value of the below market rate loan? Assume the market return on equivalent risk projects is 10 %. 10 = − ,3 000 − 100 ,000 NPV 100 ,000 ∑ t 10 t=1 10.1( ) 10.1( ) = 100 ,000 − 56 ,988 = $43 ,012 Slide 10–6 What is an Efficient Market? • 1953 – Maurice Kendall, a British statistician, presents a paper to the Royal Statistical Society on the behavior of stock & commodity prices • He had expected to find regular & predictable price cycles, but none appeared to exist • Kendall’s results had been proposed by a French doctoral student, Louis Bachelier, 53 years earlier.

Res., 1(8)854-862, 2011 Journal of Basic and Applied © 2011, TextRoad Publication Scientific Research www.textroad.com Analysis and Diagnosis of Calendar Effect in Tehran Stock Exchange Mohsen Nazari1 and Mona AkbariRad2 1Faculty member in Faculty of Management University of Tehran Tehran, Iran. 2 MBA of TEHRAN University, Iran. ABSTRACT This research has been done in order to examine the efficiency of Tehran Stock Exchange from a new aspect that challenges the Weak Efficiency Hypotheses and its main goal is analysis and recognition of calendar effect in Tehran security exchange during different months. For evaluating and testing our claim about the meaningful different return, trades volume and variability of return during different month of year we calculated the dependent variables of market return, trades volume and variability of market return by using data of the Overall Index of Tehran Stock Exchange (from April of 2002 up to September of 2009) and then by using virtual variables of months the regression between the dependent variables modeled. At the other hand this phenomena has been analyzed in 34 different industry listed in Tehran Stock Exchange separately. Analyzing the 37 regression equation resulted from our modeling, shows the variation of month during the years affects variables of the market return and its volume and variability and consequently implying the lack of Weak Efficiency Hypotheses in Tehran Stock Exchange market in low level. KEY WORDS: Calendar effect, efficient market hypothesis, Monthly Effect, ARCH/GARCH Model, Tehran Stock Exchange, emerging markets. JEL Category: C12, C13, G14, C22, G12 1.

  • CHAPTER - in REVIEW of LITERATURE
    CHAPTER - in REVIEW OF LITERATURE Introduction Conceptual Framework Securities Initial Public Offering Right Share Issue, Cash Dividend and Stock Dividend Stock Valuation Models Approaches of Security Price Analysis Return and Risk of Investment Capital Market Efficiency Anomalies of Efficient Capital Market Hypothesis Evidence Supporting the Efficient Market Hypothesis Conclusion 3.1 Introduction 3.1.1 Many general investors are confused about the stock market prices in the market. The investor's main dilemma is that whether or not to invest in the particular asset/ assets, so that they can get better sustainable and fair return of their investment with bearing minimum/zero risk. In this point of view, many people have been studying the way security price fluctuate for over a century. In 1841, Charles Mackay assembled a book of readings about Tulip-mania and some equally famous market "bubbles" which had a self-explanatory title: Extraordinary Popular Delusions and the Madness of Crowds.' In contrast to Mackey's astonishing stories, in 1900 a French mathematician named Louis Bachelier set a forth formal models in which security prices were random outcomes that had probabilities attached to them.^ The mathematician Bachelier was one of the first who studied security price movement mathematically. 3.1.2 After that, in 1936 the famous economist John Maynard Keynes suggested, "most of these persons are, in fact, largely concerned, not with making superior long-range forecasts of the probable yield of an investment over its valuation a short time ahead of the general public. They are concerned, not with what an investment is really worth to a man who buys it "for keeps," but with what the market will value it at, under the influence of mass psychology, three month or a year hence..

  • Analysis of Key Drivers of Trading Performance
    Analysis of Key Drivers of Trading Performance Bogdan Batrinca A dissertation submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy of University College London Department of Computer Science University College London 2016 2 Declaration I, Bogdan Batrinca, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. …………………………………………… Bogdan Batrinca 3 Abstract This thesis is an applied study for understanding the key factors of trading volume, providing an in-depth investigation of liquidity demand and market impact. This research was conducted in collaboration with Deutsche Bank and presents a series of empirical studies, which examine several underlying factors affecting trading volume when executing orders algorithmically in the European equity markets, which ultimately translates into trading performance and liquidity modelling. This addresses several aspects: the size of the liquidity demand relative to the predicted or actual volumes traded in the market; the choice of execution strategy given the liquidity properties of the stock; and the timing of the trade, given the market circumstances and released or anticipated company news. All of these reflect the investment skill of the portfolio manager and the execution skill of the trader, and to some extent the quality of the execution algorithm being used. The motivation is to investigate various factors that adversely affect the trading performance of algorithms, causing them to have excessive market impact or to under-participate when the market experiences periods of higher volatility. Although measuring the market fairness and efficiency is a crucial component for understanding the execution style and improving trading performance, the research into how to model and decompose trading performance requires further investigation.

The findings are analysed with the intention of de- veloping investment strategies and to investigate if behavioural finance can help to explain the existence of seasonal anomalies. Background: A number of previous studies have found evidence of seasonal anomalies in global stock markets, and by challenging the core assumptions of market efficiency, such anomalies may make it possible to predict the movement of stock prices at certain periods during the year. Consequently, there may be substantial profit- making opportunities that

  • The Nepalese Stock Market: Efficiency and Calendar Anomalies
    Munich Personal RePEc Archive The Nepalese stock market: Efficiency and calendar anomalies Joshi, Nayan and K.C, Fatta Bahadur April 2005 Online at https://mpra.ub.uni-muenchen.de/26999/ MPRA Paper No. 26999, posted 26 Nov 2010 16:55 UTC THE NEPALESE STOCK MARKET: EFFICIENCY AND CALENDAR ANOMALIES Fatta Bahadur K.C., PhD∗ and Nayan Krishna Joshi, MBS♣ ABSTRACT After describing the various forms of efficiency and calendar anomalies observed in many developed and emerging markets according to the existing literature, the present study examines this phenomenon empirically in the Nepalese stock market for daily data of Nepal Stock Exchange Index from February 1, 1995 to December 31, 2004 covering approximately ten years. Using regression model with dummies, we find persistent evidence of day-of-the- week anomaly but disappearing holiday effect, turn-of-the-month effect and time- of-the-month effect. We also document no evidence of month-of-the-year anomaly and half-month effect. Our result for the month-of-the-year anomaly is consistent to the finding observed for the Jordanian stock market and that for the day-of-the- week anomaly to the Greek stock market .In addition, our finding regarding half- month effect is consistent with the US market. For the rest, we find inconsistent results with that in the international markets. Our results indicate that the Nepalese stock market is not efficient in weak form with regard to the day-of-the- week anomaly but weakly efficient with respect to the other anomalies. I. INTRODUCTION In the past two decades, much evidence has accumulated on “calendar anomalies” in developed and emerging markets1 followed by Fama’s (1970) influential paper, “Efficient Capital Markets: A Review of Theory and Empirical Work”.

  • Januari Effect in the Indonesian Stock Exchange: Comparison of Big and Small Cap Stocks
    ISSN Online: 2477-2984 ISSN Cetak: 1878-6579 JANUARI EFFECT IN THE INDONESIAN STOCK EXCHANGE: COMPARISON OF BIG AND SMALL CAP STOCKS ARDIANSYAH JAPLANI [email protected] Universitas Muhammadiyah Metro ABSTRACT Researchers have detected in the financial markets the presence of the January effect, which refers to the historical patterns of higher returns in January than that of the other months(Feb-Dec). This study investigates that the exixtence of January effect on small capitalization stocks is much stronger than the big capitalization stocks in Indonesian stock exchange. We found that there is no January effect in Indonesian Stock Exchange. We explain this phenomenon by examining all stocks, as measured by the t test and analysis regression of dummy. We still use the similiar procedure by using t test and dummy regression, but the sample is divided into big and small capitalization stocks. We found that the January effect is stronger for big capitalization stocks than the small capitalization stocks. Keywords: Stock returns, Big capitalization stocks, small capitalization stocks, T test, and Regression of dummy. Introduction Background The effectiveness of stocks market information, the first mentioned by Fama et al. (1969), was on the agenda of the financial community since then. According to Fama (1970) influential review of the theoretical and empirical work on efficient capital markets, finance literature has dominated by working on large informational efficiency. However, the efficient market hypothesis has never been out of the question. For example, any predictable pattern of stock returns as evidence againts the theory of efficient markets. A well-known objection to the market efficiency in this type arises from the seasonality of stocks returns.
