[BRIEFING.COM] The S&P 500 (-0.32%) is today's top lagging major average, down about 18 points.

Briefly, S&P 500 constituents Lockheed Martin (LMT 437.64, -29.10, -6.23%), MGM Resorts (MGM 31.25, -1.28, -3.93%), and Weyerhaeuser (WY 29.12, -0.99, -3.29%) hold decent losses. LMT falls after the Trump administration chose embattled aerospace and defense company Boeing (BA 180.10, +7.27, +4.21%) to lead the next generation of fighter jet programs, while MGM falls despite the March Madness tournament getting underway.

Meanwhile, Super Micro Computer (SMCI 42.20, +3.10, +7.93%) is atop the standings after JP Morgan upgraded the stock to Neutral amid stronger demand and supply improvements.
