Stock Market Anomalies In Emerging Markets Some Evidence From Egypt PDF Download

The main objective of this thesis is to investigate the short and long-term overreaction phenomenon in the Egyptian stock market. In addition, the thesis investigates links between stock market regulatory policies (price limits and circuit breakers) and the profitability of contrarian strategies. Finally, the study examines the effect of regime switch - from strict price limits to circuit breakers - on the volatility spillover, delayed price discovery and trading interference hypotheses. Using data from the Egyptian stock exchange, I find that a panel data approach adds a new dimension to the existing models, offers interesting additional insights and reveals the importance of the role of unobservable firm-specific factors in addition to observable factors in the analysis of the overreaction phenomenon. Moreover, portfolios based on unobserved factors i.e. management quality, corporate governance and political connections of board members, significantly outperform traditional portfolios based on size. Results also show evidence of genuine long-term overreaction phenomenon in the Egyptian stock market as the contrarian profits of the arbitrage portfolio cannot be attributed to the small firm effect, formation period length, and stability of time varying factor or seasonality effect. Finally, switching from a strict price limit to a circuit breakers regime increases stock price volatility and disrupts the price discovery mechanism in the Egyptian stock market.
