A lot of mixed signals brought the indexes down, except the Dow that was up nearly 500 before sliding to near breakeven. The Nasdaq was down about 250 by 3:30 before recovering about half of that in the final half hour. But mixed messages were on the one hand Trump proclaiming talks going well and on the other hand taking steps to widen the war. In other bad war news, Yemen has entered the conflict on the side of Iran.
