Markets rallied last week, but Moody’s U.S. credit downgrade, rising bond yields, and tariff concerns now pressure equities. Retail earnings and sentiment data loom large.

The Moody’s announcement sent the yield on a 30-year Treasury bond to a high of 5.01% at one point on Monday. Bond yields rise as bond prices fall. When a selloff hits and demand for bonds dries up, it sends bond prices lower. In turn, bond yields move higher.

Moody's on Monday downgraded the long-term ratings of top American lenders such as JPMorgan Chase , Bank of America and Wells Fargo , after pushing the U.S. out of top triple-A rating club over its burgeoning $36 trillion debt.
