Why is BIST 100 down at midday?

The decline followed stronger-than-expected US inflation and heavy technology selling in global markets. The pressure was also visible at the open, when BIST 100 started at 12,053 points, down 0.5 percent, Anadolu Agency reported.

The index had closed at 12,118 points on October 14 after falling 1.1 percent. The same backdrop pushed banking and industrial shares lower in the previous session, Hibya said.
