US futures are slightly higher this morning as earnings season goes into full swing. So far the majority of earnings have come in better than expected on the bottom line but geopolitical tensions around North Korea continue to loom. In economic data, the Empire State index hit 5.2 in April compared to 16.4 in the previous month. Asian markets closed mostly lower led by the Shanghai index despite a beat in Chinaâ€™s GDP. Markets in Europe are trading lower led by the CAC. Later today, the NAHB survey will be released.
