昨天我们发表了一篇有关工业3D打印企业的最近股价变动Company.
现在，北亨廷顿总部总部制造商宣布了这一消息，可以解释公司股票中看到的交易量增加。
ExOne现任首席执行官詹姆斯·L·麦卡利（James L. McCarley）威尔（James L. McCarley）将“离开公司立即寻求其他利益和机会。”
承担ExOne CEO的位置是美国肯特Rockwell. Rockwell’s most recent job at ExOne was as Executive Chairman, however he previously served as CEO from January 1, 2013 until August 19, 2016. He has been involved with the company since 2007 as an investor and executive.
On the new appointment Rockwell said, “On behalf of our Board and management team, I would like to thank Jim for his efforts and wish him all the best in his future endeavors.”
股价运动告诉我们什么？
It may be tempting to make assumptions about the prospects of a company based upon the markets reaction to the new CEO. If the share price increases, it could be argued that the incomer is viewed as likely to have a positive effect – and vice versa.
However, research indicates that such a conclusion may be overly simplistic. In the哈佛商业评论, James M. Citrin, an executive recruiter who leads斯宾塞·斯图尔特（Spencer Stuart）北美董事会兼首席执行官实践，写道
“We examined the short- and long-term share-price performance of 314 companies that named new CEOs from 2004 to 2009. Of the 49% of companies that saw a first-day rise, just over half—55%—also experienced a long-term gain. And of the 49% of companies that saw a first-day drop, about the same proportion—59%—experienced a long-term gain. (For the remaining 2% of companies, share price on the day of the appointment remained flat.)”
Citrin在同一篇文章中解释说：“当市场对首席执行官新闻的反应是戏剧性的时，就会发挥出令人惊讶的关系。Of the 20 companies whose stock popped 5% or more upon the announcement, only 40% sustained a rise over the course of the CEO’s tenure—but of the 14 companies whose stock plunged 5% or more upon the announcement, 79% experienced a long-term gain.”
查看两个主要的3D印刷企业的股价，以及市场如何应对CEO的变更提供以下信息。
Vyomesh Joshi于2016年4月4日被任命为3D Systems的首席执行官。在宣布公告之前，3D系统的股价为15.12美元，此后立即上涨了4.63％。什么时候Stratasys宣布Ilan Levin担任首席执行官2016年6月，股价上涨了1.79％。
最近，Stratasysannounced that CEO Ilan Levinwould be replaced in the interim by Elan Jaglom. The share price of Stratasys saw a 0.25% decrease.
对于Exone而言，昨天市场关闭和今天的Rockwell宣布之间的股价变动降低了1.87％。这个数字是否可以预测Exone的长期前景，还是较高的5天增长率为22％，是一个冒险进入水晶球凝视领域的问题。
