SPX昨日大跌探测200SMA，今日开盘后接着大跌继续探测200SMA。在14：35开始拉回。

Kleinfeld also said Alcoa was well positioned to grow as the broader economy recovers, and that some end markets -- such as the U.S. beverage can and auto markets -- showed signs of stabilizing.
Still, the largest U.S. aluminum producer, which makes the metal and uses it to manufacture products such as truck wheels and fighter jet parts, is maintaining its forecast of an industrywide contraction of 7 percent this year, he said.
Pittsburgh-based Alcoa's loss amounted to 47 cents per share for the three months ended in June. During the same period last year, the company earned $546 million, or 66 cents per share.
Alcoa's loss from continuing operations in the latest quarter was $312 million, or 32 cents per share. Excluding restructuring charges, that loss would have been 26 cents per share.
Revenue tumbled 41 percent to $4.24 billion.
Analysts expected Alcoa to lose 38 cents per share on revenue of $3.93 billion, on average, according to a survey by Thomson Reuters. Wall Street typically excludes one-time charges in its estimates.
