Apple's stock has regained some $82 billion in market capitalization in just the last seven weeks, closing today just shy of $610, the first time the stock has ended the trading day over $600 per share since late April. It hit a low of $530 per share in mid-May but has steadily climbed back since then, and is trading above $610 in after-hours activity this evening. Predictions of strong foreign sales may be behind the recent rise.
