In this paper, we analyze about the relation between stock price returns and Headline News. Headline News is very important sources of information in asset management, and is sent in large quantities every day. We study the effect of more than 13,000 Headline News sent from JIJI PRESS. We classify Headline News using Text Categorization and analyze the reaction of a stock price return for every...

Recent works have shown that social media platforms are able to influence the trends of stock price movements. However, existing works have majorly focused on the U.S. stock market and lacked attention to certain emerging countries such as China, where retail investors dominate the market. In this regard, as retail investors are prone to be influenced by news or other social media, psychologica...

This letter is intended to demonstrate that price inflation and stock returns display differing relationships depending on the measure of inflation used. Using data from 1966 – 2009, it appears that no correlation exists between any measure of price inflation and stock returns or dividend yield in the period 1983 – 2009. We do find a negative correlation between monetary inflation and dividend ...

We present an algorithm producing a dynamic non-self-financing hedging strategy in an incomplete market corresponding to investor-relevant risk criterion. The optimization is a twostage process that first determines market calibrated model parameters that correspond to the market price of the option being hedged. In the second stage, an optimal set of model parameters is chosen from the market ...

Soft computing is a part of an artificial intelligence, and fuzzy logic is the study of fuzziness on data. The combination of these two techniques can provide an intelligent system with more ability and flexibility. The nature of data in the stock/capital market is more complex and challenging to predict the movement of the price of the stock. The study has combined both fuzzy c-means and neura...

Using a new hand-collected data set, this study examines the stock price manipulation in the Taiwan Stock Exchange (TSE). We examine the characteristics of the manipulated stocks, and their impacts on market quality. The results show that manipulated stocks tend to be small. The stock prices rise throughout the manipulation period, followed by a price reversal. The average cumulative abnormal r...

This article investigates the association between stock market activity and mental well-being, exploiting the availability of interview dates in the British Household Panel Survey to match changes in the FTSE 100 stock price index to respondents over the period 1991–2008. We present evidence that annual changes in the price index are associated with better mental well-being whilst greater uncer...

We examine the stock price reaction to announcements that firms are alleged to be doing fraudulent financial reporting or manipulating earnings, using a sample of firms cited by the Securities Exchange Commission (SEC) in its Accounting and Auditing Enforcement Releases (AAERs) during the time period 1985-2005. We find a total 14% drop in stock price over a three day window surrounding the anno...

The present study explores the effect of the gambler’s fallacy on stock trading volumes. I hypothesize that if a stock’s price rises (falls) during a number of consecutive trading days, then the gambler’s fallacy may cause at least some of the investors to expect that the stock’s price “has” to subsequently fall (rise), and thus, to increase their willingness to sell (buy) the stock, resulting ...

The article shows that two measures of the amount of private information in stock price—price nonsynchronicity and probability of informed trading (PIN)—have a strong positive effect on the sensitivity of corporate investment to stock price. Moreover, the effect is robust to the inclusion of controls for managerial information and for other information-related variables. The results suggest tha...
