An Announcement effect on Stock Prices-An Pham Investment

Announcement effect broadly refers to the impact that any type of news or public announcement — especially when issued by government or monetary authorities — has on financial markets. It is most often used when speaking of a change in security prices or market volatility that results directly from a piece of significant news or a public announcement. It also could refer to how the market would react upon hearing the news that a change will occur at some point in the future.
