这个被称为"巴菲特指标"的估值工具，是通过衡量美股整体市值（以Wilshire 5000指数为代表）与美国 GDP总量的比值来判断市场估值水平。目前，这一比例约为180%，处于去年9月以来的最低水平，尽管 近几周股市强势反弹，但该指标仍未回升至去年高点。 虽然目前的180%远高于疫情期间2020年初的低点（当时接近100%），但在美股估值整体回落、S&P 500指数自4月低点反弹约12%的背景下，市场参与者对是否继续"追高"或开始对冲风险正产生分歧。 投资公司50 Park Investments创始人亚当·萨尔罕表示："这是一个关键指标，它能帮助交易者判断何时投 入资金。"他本人近期大举加仓科技股，"只要特朗普在贸易战上不'硬碰硬'，投资人就会持续买入。" 目前市场也在密切关注下周的美联储会议以及接下来的财报季，它们可能成为左右市场下一阶段走势的 关键因素。 其他估值工具也传递出类似信息。例如，S&P 500目前的前瞻市盈率为20.6倍，虽然高于10年平均的 18.6倍，但比年初下跌了约8%，显示估值正逐步回归合理。 "股神"巴菲特最看重的估值指标，正释放出美股"抄底"信号，支持当前美股强劲反弹行情仍有上涨 ...

今天白天很意外，拖了2个多月的阿里数学竞赛突然就公布了比赛结果，还专门附带了备受关注的那对师生的调查结果。之所以意外是因为我上个月有一 篇文章质疑阿里为什么迟迟不公布结果，被删了，当时我以为这件事也会冷处理，拖时间不了了之。 事情的真相倒在意料之中，初赛是老师"帮忙"答题，复赛师生两人都未得奖。阿里承认赛制设计不完善，涟水中专对老师也进行了处罚。 我白天发的短评里也说了，文科有可能靠自己的天赋自学成才，高等数学你有实力的话一定是有迹可循的，绝对不会埋没人才。事实上这一次初赛入围的 年纪最小的是一个上海华育中学的初中生，他的复赛成绩获得了铜奖，但从头至尾很少有人会去质疑他的真实性，因为这个初中生是圈内有名的少年天 才。 怀才就像怀孕，它有一个逐渐发展的过程，时间久了肯定能看出来。不可能你上个月还来月经，这个月就要临产了。 其实当时新闻发出来以后，很快就引起了巨大争议，但一些专业人士的质疑被解读为他们心胸狭隘容不下平民天才。很多人希望借着这件事否定现行的教 育选材机制，哪怕是今天官方公布了调查结果，微博和小红书上依然有人怀疑这是学阀们故意打压的阴谋论。 其实要我说这件事发展到这个地步，和某几个大官媒在未经调查的情 ...
