Oil prices fell and stocks climbed in early trading on Monday, indicating optimism among investors about the limits of economic fallout from the ongoing Israel-Iran conflict. The Dow Jones Industrial Average surged 415 points, or 1%, erasing much of the losses suffered on Friday as back-and-forth strikes broke out between the two countries.

As Israel and Iran exchanged more attacks, stock markets mostly rose even as worries remained about possible oil supply interruptions.
