The Dow Jones Industrial Average (DJI) is on track for its fifth-straight weekly loss at midday. Despite sporting a 98-point lead this afternoon, the uncertainty around Russia's invasion of Ukraine, and the subsequent surge in oil and commodity prices weighed on the blue-chip benchmark this week. Meanwhile, the S&P 500 Index (SPX) is hovering near breakeven, while the Nasdaq Composite (IXIC) is firmly in the red, as both indexes head for their second consecutive weekly loss.

In other news, U.S. President Joe Biden is looking to revoke Russia's "most favored nation" trade status, while lawmakers propose to remove the country from the World Trade Organization (WTO).
