此前数日上涨的科技股在周一交易日一度上涨后下跌,脸书、亚马逊、网飞、微软、Alphabet等均出现下跌。
道琼斯指数和标普500指数连续两周上涨,科技股的反弹推动纳斯达克指数在连续三周上涨后创下新高。7月,道琼斯指数和标普500指数分别上涨了1.0%和2.7%。科技股为主的纳斯达克表现更好,本月上涨10.7%,亚马逊、苹果、网飞、Alphabet都创出新高。
有华尔街分析警告称,目前各股上涨的区间仍然有限,部分高股价的科技股正在被超买,因此对于前景持谨慎态度。
From January 2015, she started to practice leetcode questions; she trains herself to stay focus, develops "muscle" memory when she practices those questions one by one. 2015年初, Julia开始参与做Leetcode, 开通自己第一个博客. 刷Leet code的题目, 她看了很多的代码, 每个人那学一点, 也开通Github, 发表自己的代码, 尝试写自己的一些体会. She learns from her favorite sports – tennis, 10,000 serves practice builds up good memory for a great serve. Just keep going. Hard work beats talent when talent fails to work hard.
