Market analysts note Dow futures stabilized as Treasury yields eased slightly. Lower yields typically improve equity valuations, lifting dividend-heavy Dow constituents. The quiet trading came as a midnight deadline approached, when the U.S. government could shut down because of Washington’s latest political impasse. That’s because history has shown that past shutdowns have had limited impact on the economy and stock market, and many economists and professional investors expect something similar this time around. US stocks edged lower on Tuesday morning as the chance of a government shutdown and new lumber tariffs weighed on equities. With weekly jobless claims coming in below expectations, Dow futures ticked higher, signaling renewed faith in labor market strength. Economists warn that sustained tightness could prolong restrictive monetary policy.
