NEW YORK (AP) — U.S. stocks are nudging lower on Tuesday, and oil prices are rising again. It’s a modest return to form for financial markets after worries had seemed to calm on Wall Street Monday.

Calm returned to Wall Street, and U.S. stocks rallied, while oil prices gave back some of their initial spurts following Israel’s attack on Iranian nuclear and military targets at the end of last week.

By Johann M Cherian and Amanda Cooper LONDON (Reuters) -Stocks fell, while oil and gold rose on Tuesday, as fighting between Israel and Iran entered a fifth day, raising investor concerns over the risk of a broader regional conflict in a week packed with key central bank decisions.
