华尔街延续涨势
美国股市周二开盘，延续本周初的涨势，三大股指均大幅走高。
华尔街最广泛的衡量指标标准普尔 500 指数 (SPX) 在上午晚些时候上涨 2.1%，而道琼斯指数 (INDU) 上涨 1.6%，即 565 点。周一落后于其他指数的纳斯达克综合指数 (COMP) 在上午晚些时候上涨了 2.8%。
“暂时忘掉‘好转'，本周二看起来更像是一次了不起的好转，”Bespoke Investments 的分析师表示。
几周以来，市场一直动荡不安，首先是因为对 Omicron 变体的担忧而动摇，然后是美联储宣布可能比预期更早结束其大流行时期的刺激计划。
但周一的上涨可能更多地与技术因素有关：现在是年底，主要股指有可观的回报。标准普尔指数上涨超过 22%，而纳斯达克指数上涨超过 18%，道琼斯指数上涨超过 15%。对于重新考虑他们想要钱的地方的投资者来说，这可能是他们调整投资组合的时候。
下周星期五也是四种金融资产合约到期的“四重巫术”。这通常是一段波动期，投资者可能已经为此做好了准备。
Wall Street extends rally
The US stock market is off to the races on Tuesday, extending its rally from the start of the week as all three major indexes kicked the day off sharply higher.
The S&P 500 (SPX), Wall Street's broadest gauge, was up 2.1% in the late morning, while the Dow (INDU) rose 1.6%, or 565 points. The Nasdaq Composite (COMP), which had lagged behind the others on Monday, gained 2.8% in the late morning.
"Forget about a 'turnaround' for now, this Tuesday is looking more like a terrific one," said analysts at Bespoke Investments of the rally.
It has been a volatile few weeks in the market, which was first shaken by worries about the Omicron variant, then by the Federal Reserve's announcement that it might end its pandemic-era stimulus program sooner than expected.
But Monday's ascent may have had more to do with technical factors: It's the end of the year and the major indexes have decent returns to show for themselves. The S&P is up more than 22%, while the Nasdaq has climbed more than 18% and the Dow more than 15%. For investors rethinking where they want their money, this might be a time of shifting their portfolio around.
Next week Friday is also what's known as "quadruple witching" when contracts on four types of financial assets expire. It's often a period of some volatility, and investors may already be preparing for it.
