Indian Stock Market

In a first of this kind, this paper examines the issue of prior return effect in Indian stock market in intra-day analysis using high frequency data. We document that in Indian stock market, security returns exhibit a reversal in their direction within few minutes of extreme price rises as well as price falls. However the speed with which the correction takes place is slightly different for good news events and bad news events. Indian investors tend to be optimistic as they immediately bring stock prices up following unjustified price falls but take time to bring stock prices down following unjustified price rises. These findings lend a further support to short-term overreaction literature. More importantly, these findings serve as a proof of predictability of the direction of future stock prices and consequent returns on an intra-day basis. It forwards important investment implications for traders, fund managers, and investors at large.

The objective of this study is to determine whether companies listed on the Johannesburg Stock Exchange overreacted to unexpected favourable and unfavourable company-specific news events during the period 1970 - 1984. The JSE appears to be inefficient in reacting to the announcement of unfavourable news; economically significant abnormal returns up to one year following the event are observed. The JSE does not appear to overreact to news of a favourable nature, there is only weak evidence of short-term overreaction. The selling pressure caused by panic selling could depress prices well below levels justified by the unfavourable news. The magnitude of the overreaction to unfavourable news is sufficient to enable astute investors to outperform the market by taking positions in these securities. Knowledge of the pattern of market overreaction can also be of value to investors for transactions that are to take place anyway.

Over Time

This study analyzes citizen representations in a corpus of 300 Dutch newspaper narratives published between 1860 and 2009. Results show that citizen perspectives are more frequently represented than authority perspectives, although the perspectives of authorities have become somewhat more frequent over time. In-depth analyses of the citizen perspectives show that citizens may fulfil multiple roles in the crime narratives, leading up to a functional typology of citizens as (1) story characters experiencing the news events, (2) news sources providing inside information about the events, and (3) vox pops expressing opinions and evaluations of the events. The variety of citizen perspectives included in crime news narratives and the multitude of roles they fulfill may help audience members to become informed as well as engaged and to explore their personal emotions, which may ultimately reinforce moral, cultural and societal values.
