Trading in New York Stock Exchange-listed stocks on Monday were exhibiting panic-like-selling behavior as global stocks confronted a sharp selloff that has been attributed partly to concerns about the collapse of Chinese developer Evergrande. The NYSE Arms Index, a volume weighted breadth measure that tracks the ratio of advancing stock to declining stocks over the ratio of advancing volume over declining volume, was showing a reading of 2.088 for NYSE-listed shares.

was trading 2.8% lower at 14,616.
