What's driving the market?

A sinking dollar has grabbed the limelight to start 2018, kicking off the new year the same way it ended, slumping.

The ICE U.S. Dollar Index fell for a fifth straight session, down 0.3% at 91.886 to trade around its lowest level since September. The weakness came as investors expressed doubts that major U.S. tax reforms written into law late December would have on economic growth, interest rates and inflation.

Outside the U.S., Iran was in focus after nine people were reported dead after overnight clashes between protesters and security forces. The protests started last week over rising inflation and corruption, but focus has since shifted to a wider discontent ( with Iran's ruling system and Supreme Leader Ayatollah Ali Khamenei. The wave of unrest is now seen as the largest since a disputed 2009 presidential election.

In North Korea, leader Kim Jong Un said in a speech on Monday that Pyongyang had completed its nuclear weapons program (, which he claimed would allow a missile to reach any point in the continental U.S. Kim, however, also suggested he was willing to engage in talks with South Korea, saying North Korea would be open to sending a delegation to the Winter Olympics in the South next month.

What are strategists saying?

"There's an unusual combination of strength in economies around the world, a pretty strong backdrop for commodities and exports. There's so much going right, even before the jolt of pro-business tax reform, that we think equity markets will continue to be strong in major markets in 2018," said Humberto Garcia, head of asset allocation for Bank Leumi USA.

"We think a lot about what could trigger the next downturn, and political issues are something that come up. However, with all the economic strength we see, we think that even if you had a scare, markets would recover fairly quickly," he said.

Optimism over U.S. markets have been rising despite valuations that are seen as stretched by many measures.
