And finally, Monday's after-hours session had a tech-heavy feel to it. The biggest mover was AMD ( AMD), which was under heavy selling pressure after announcing the abrupt resignation of Thomas Seifret as chief financial officer. The no. 2 chip maker behind Intel ( INTC) said Seifret, who joined AMD in 2009 and served as interim CEO in 2011, is leaving to pursue other opportunities. The stock was last quoted at $3.60, down 10.2%, on volume of 1.71 million, according to Nasdaq.com. Meantime, Apple ( AAPL) was making waves in late trades after the iconic company saw its shares crest above $700 for the first time ever in extended trades. The stock ran as high as $701.79 -- a new all-time peak -- after the bell, and last traded at $701.44, up 1.7%, on volume of more than 530,000. The move follows a 1%-plus jump in regular trades after Apple confirmed the iPhone 5 was an unmitigated success, selling more than 2 million units during its first 24 hours of pre-orders. -- Written by Michael Baron in New York. >To contact the writer of this article, click here: Michael Baron.
