摘要
股票市场中航天版块的市场行情除受到大盘的影响之外,还与航天产业重大事件有着密切的联系。运用事件研究法分析重大航天事件对中国股票市场航天版块行情的影响可以看出:航天重大事件带来了航天板块股票市场价格在之后三个交易日内出现急剧上升或下降趋势,但影响的时间延续性较短,波动持续时间不长,股民对航天重大事件的炒作和股民“羊群效应”是航天板块在航天重大事件短期内出现短期剧烈波动的主要影响因素。
The prices of the Aerospace stocks are strongly influenced by the big events happened in aerospace industry as well as the general fluctuations in the stock market. Analysis on the influences by Eventstudy shows： the prices of the aerospace stocks will dramatically increase or decrease in three trading days immediately after some events, however, such influences won＇t keep long. Speculations to the events and Herd Behavior are the two main factors leading to aerospace stocks fluctuate dramatically in short term.
