[BRIEFING.COM] The S&P 500 (-1.54%) is in second place on Friday afternoon, down about 90 points.
Elsewhere, S&P 500 constituents Omnicom (OMC 97.08, -7.96, -7.58%), Moderna (MRNA 36.99, -2.78, -6.99%), and Warner Bros. Discovery (WBD 9.19, -0.67, -6.80%) pepper the bottom of the average. OMC and MRNA weakness has been attributed in part to news that President-elect Trump will nominate Robert Kennedy Jr. as Secretary of the Dept. of Health and Human Services.
Meanwhile, Palantir Technologies (PLTR 64.66, +5.48, +9.26%) is atop the standings after announcing it will transfer its listing to the Nasdaq from the NYSE.
