NEW YORK (AP) — Shares ended an up-and-down week on a down word on Wall Road Friday, taking 0. 7% off the S&P 500. The benchmark index logged its first weekly loss to date this month. Worries concerning the worsening pandemic and the restrictions it’s bringing are outweighing optimism concerning the progress being made on creating coronavirus vaccines. Treasury yields fell barely and inventory markets around the globe made solely modest strikes.
