Equity markets are lower across the globe, led by China. Earnings worries sent China’s Shanghai Composite Index down 6.7 percent. Hong Kong’s Hang Seng fell 1.9 percent and Japan’s Nikkei lost .4 percent.

Stocks are mostly lower across Europe. France’s CAC 40 Index and Germany’s DAX are both down .8 percent.

Construction spending and auto sales numbers are due out Tuesday. The economic calendar remains busy during the second half of the week, concluding with key monthly jobs data Friday.

Bonds are in wait-and-see mode. The benchmark ten-year Treasury bond is flat this morning and still yields 3.44 percent.
