China's new stimulus measures continued to push markets higher Tuesday morning. Stocks were extending Monday's rally as a surge in global markets bolstered market optimism. However, mixed earnings from key large-caps were undermining confidence. United Technologies (UTX) gained after reporting a 20% rise in quarterly profit, though revenue missed. The aerospace company affirmed previous sales and earnings guidance for the full year in spite of a stronger dollar. Harley-Davidson (HOG) plummeted as sales of new motorcycle declined due to aggressive discounting. The company also reduced shipment forecasts for the year.
