Stock Market Update

[BRIEFING.COM] The S&P 500 (+0.23%) is in last place on Friday afternoon, up about 15 points.

Briefly, S&P 500 constituents Dollar Tree (DLTR 125.49, +9.62, +8.30%), Moderna (MRNA 27.50, +2.01, +7.89%), and Omnicom (OMC 74.21, 4.04, +5.76%) pepper the top of the standings.  DLTR and MRNA move higher despite a dearth of corporate news, DLTR hitting a year-and-a-halt high for good measure, while OMC rallies in part based on a UBS target raise to $108 from $99.

Meanwhile, W.R. Berkley (WRB 67.63, -3.24, -4.57%) is one of today's worst performers, continuing its recent losses amid news that Mitsui Sumitomo Insurance Co., Ltd. acquired beneficial ownership of at least 12.5% of the Company's outstanding common stock; losses pile on today as investors may see the MSI purchase as already expected and offering limited new strategic upside, while recent analyst downgrades highlight weakening fundamentals and an overextended valuation.
