Not much U.S. macro news today...

... much like every single Monday. Tella Opeyemi and I argued in a 2009 paper this might be a reason for the so-called Monday effect, which is a tendency for stocks to exhibit poor performance on average on Mondays.

Our hypothesis is supported by the fact that this effect is statistically significant for stocks but also for other risky asset classes and risk-free Treasury bonds. "Investors seem to decrease their exposure to all asset classes on average on Monday, and increase their cash holdings, maybe awaiting economic and financial reports released later in the week."
