Stocks began the session in negative territory and remained there throughout the entire session. The early weakness was attributed to oil prices, which were down early and never recovered during the day. The losses of more than 5% brings the loss over the past two days to more than 10%, pushing WTI crude back below $30 a barrel and squashing equities in the process. Any hope that oil prices would de-couple from stock prices will have to wait another day as the two continue to move in lockstep with each other. Even a solid earnings report from tech bellwether Alphabet (GOOG) could not help the market.

ECONOMIC EVENTS: In the U.S., the economic calendar was quiet.

In central bank news, the Reserve Bank of Australia and Reserve Bank of India both held their benchmark interest rates steady, as expected.
