Last week’s rally for Apple shares was driven by indications that a phase-one trade deal between the US and China was likely. Monday’s rally was likely driven by news that that had happened. Apple shares hit new intraday and closing highs on Monday. Shares Monday hit as high as $280.79 before closing close to a dollar under that. Apple’s official closing price was $279.86 - nearly five-dollars higher than Friday’s close of $275.15.
