theories and the existing studies predict different the relationship between external financing and investing activities and the stock returns. but almost of them predict that there is negative relationship separately between financing and investing activities with stock returns. this study examined the assumption that there is a significantly negative relationship between external financing ac...

Stock based rewards are often used to motivate high-level managers to take actions to increase the stock price of the fi rm. However, numerous constraints may weaken the perceived link between individual effort and stock price appreciation for many recipients. This study introduces a new construct, stock price expectancy, which we defi ne as individuals’ perceptions of infl uence over their fi ...

A number of research had been carried out to forecast stock price based on technical indicators, which rely purely on historical stock price data. Nevertheless, their performance is not always satisfactory. In this paper, the effect of using hybrid market indicators of technical, fundamental indicators and experts opinion for stock price prediction is examined. Input variables extracted from th...

Empirical evidence is given for a significant difference in the collective trend of the share prices during the stock index rising and falling periods. Data on the Dow Jones Industrial Average and its stock components are studied between 1991 and 2008. Pearson-type correlations are computed between the stocks and averaged over stock pairs and time. The results indicate a general trend: whenever...

Data mining using integration of clustering and decision tree algorithm has been proposed for predicting the stock market prices. This mechanism involves studying stock price patterns in time by attempting to predict future results of a time-series by simply studying patterns in the time-series of stock prices. The goal of this project is to implement data mining in order to predict the Time-Se...

Previous studies have examined the manipulation of executive stock option awards and exercises, focusing on information timing by managers. In this paper, we investigate potential managerial manipulation of stock-price performance motivated by executive stock options. To distinguish performance manipulation from information timing, we examine stock-price performance surrounding the departure of...
