 -  The benchmark S&P 500 slipped 9 points on Friday to close the year at 3,839, down nearly 20% in 2022.
-  The Dow fell 73 points to close the year at 33,147, down about 9% in 2022.
-  The tech-heavy Nasdaq fared worst of all in 2022: It fell 11 points on Friday to close the year at 10,466, down about 33% since January.
