Stock Market Update

[BRIEFING.COM] The Dow Jones Industrial Average trades almost 600 points lower than its prior close. The DJIA is sitting on a 1.1% decline this week. 

Walmart (WMT 97.53, -6.46, -6.2%) is the worst performer in terms of percentage decline after its earnings report, which was accompanied by disappointing fiscal Q1 and full-year guidance. WMT is among the least influential stocks in the price-weighted average, though. 

The outsized decline in its top-weighted component Goldman Sachs (GS 635.15, -32.72, -4.9%) has played a bigger role in the weighing down the Dow. There's no specific catalyst for the selling in GS.
