U.S. futures are holding gains despite a weaker retail sales report. Optimism overseas improved sentiment this morning after China reported strong manufacturing data. On the U.S. data front, February retail sales fell 0.2%, while analysts were looking for a 0.3% gain. Retail sales ex-auto and gas fell 0.6%, with analysts expecting a 0.4% gain. Markets will get a look at additional data later this morning with the release of March PMI manufacturing index and the ISM manufacturing index, as well as business inventories from January and construction spending from February. European shares are higher, with material stocks leading, after strong data out of China gave that sector a boost. Asian markets closed broadly higher with Chinese stocks leading after PMI data out of China showed expansion in March.
