欧盟委员会：批准61亿欧元用于援助乌克兰国防。

8月21日A股低于3%换手率股票占比升至66.71%，刷新4月以来新高；高于5%换手率股票占比小幅降至17.79%，再次逼近阈值水平；整体来看换手率仍在延续7月以来震荡下行的趋势。 -------- 注：1、当换手率低于3%的股票占比上升，尤其是接近历史高位附近（图中虚线，图为反转走势）时，意味着市场很有可能遇到一个阶段低点，容易产生反转或反弹。 2、当高换手率高于5%的股票占市场总数比例保持在阈值（图中虚线）上方，市场才会出现强的赚钱效应，使得行情具有持续性。牛市的时候，该指标会持续保持在阈值上方，市场迎来普涨行情；而熊市的时候，该指标大多时候在阈值下方，偶尔超过阈值反而要小心冲高回落的风险。

Bank strategist Ipek Ozkardeskaya said US Treasury bond purchases to suppress yields may prevent markets from fully pricing inflation and fiscal risk and could blunt market reactions to Federal Reserve policy. That, she warned, may make it harder for the Fed to pull inflation back toward its 2% target — an outcome Fed chair Kevin Warsh would want to avoid. Ozkardeskaya added this week's Jackson Hole meeting could clarify how the Fed will fit into government policy plans.
