美国股市周一大幅上涨，此前有消息称生产新冠肺炎疫苗的主要进展。
截至周一收盘时，道琼斯工业平均指数飙升逾830点，涨幅约3%。截至下午，该指数早盘有所上涨，但短暂触及盘中高点。
与此同时，截至周一下午，标准普尔500指数股市飙升逾1%，跌幅超过此前的涨幅。与此同时，科技股为主的纳斯达克周一收盘下跌1.5%，主要受大流行赢家大幅下跌的推动——网飞下跌约8.6%，Zoom下跌17.4%，Peleton下跌20.3%。
制药巨头辉瑞及其合作伙伴生物技术公司周一上午在一份声明中表示，根据一项早期分析，他们的疫苗“被发现在预防新冠肺炎方面有超过90%的有效性”，该分析包括94例在试验参与者中确诊的新冠肺炎病例，这似乎引发了早市的反弹。
独立顾问联盟首席投资官克里斯·扎卡雷利在周一早上的评论中称这一消息“改变了游戏规则”。
扎卡雷利补充说:“就消费者支出和经济活动因对日益增多的新冠肺炎病例的担忧而受到抑制而言，任何能够扭转这一趋势的举措都将受到市场的欢迎。”。

几个月来，经济学家和分析师一直表示，从新冠肺炎危机中全面恢复经济仍取决于疫苗或病毒的有效治疗。
消息传出后，辉瑞股价上涨7.7%。旅游行业也大幅上涨——邮轮运营商嘉年华的股价上涨约39%，美国航空公司的股价上涨15%，达美航空公司的股价上涨17%。迪士尼股票上涨近12%。
前副总统乔·拜登显然是美国总统大选的获胜者的消息也平息了一些投资者数月来一直笼罩在心头的不确定性。华尔街似乎也欢迎选举后政府分裂的可能性，这意味着极端的政策变化不太可能会扰乱市场。
Dow Jones soars more than 800 points on vaccine hopes
U.S. stocks rose sharply on Monday after news broke of amajor development in producing a COVID-19 vaccine.
The Dow Jones Industrial Average skyrocketed more than 830 points, or approximately 3%, by the time markets closed Monday. The index shed some earlier gains by the afternoon but briefly hit an intraday record high.
The S&P 500, meanwhile, spiked by more than 1% by Monday afternoon, shedding earlier gains. The tech-heavy Nasdaq, meanwhile, closed down 1.5% on Monday, largely driven by some steep losses in pandemic winners -- Netflix shed some 8.6%, Zoom lost 17.4% and Peleton slid 20.3%.
Pharmaceutical giant Pfizer and partner Biotech said in a statement Monday morning that their vaccine was "found to be more than 90% effective in preventing COVID-19" according to an early analysis that included 94 confirmed cases of COVID-19 in trial participants, which seemed to spark the morning market rally.
Chris Zaccarelli, chief investment officer for Independent Advisor Alliance, called that this news a "game-changer" in a commentary Monday morning.
"To the extent that consumer spending and economic activity have been suppressed by concerns of the increasing Covid cases, anything that can reverse that trend will be welcomed by the markets," Zaccarelli added.
Economists and analysts have said for months that a full economic recovery from the COVID-19 crisis remains contingent on a vaccine or effective treatment for the virus.
Pfizer shares gained 7.7% after the news. The travel sector also saw large gains -- shares for cruise operator Carnival were up some 39%, while American Airlines shares rose 15% and Delta Air Lines shares climbed 17%. Disney stock climbed nearly 12%.
News that Former Vice President Joe Biden is the apparent winner of the U.S. presidency also quelled uncertainty for some investors that had loomed large for months. Wall Street also appeared to welcome the likelihood of a split government in the wake of the election, meaningextreme policy changesthat could roil markets are less likely.
