1. Inauguration day

Donald Trump is set to be sworn in as the 45th president of the United States on Friday. Trump will take the oath of office around noon.

Since his election, he has shown an uncanny ability to move markets. Investors have pushed U.S. and global stock markets higher in response to his pro-business rhetoric.

The Dow Jones industrial average has surged 7.6% since the election and even traded near 20,000 points before easing back down. The S&P 500 jumped 5.8% while the Nasdaq added 6.7% over the same period.

But the Republican has also introduced a heavy dose of uncertainty to markets. Trump has made a habit of targeting and calling out specific companies on Twitter.

He's criticized Boeing, Lockheed Martin, United Technologies, GM and Ford, as well as foreign car companies Toyota and BMW.

He has also threatened tariffs on companies building their products in Mexico instead of the U.S. and slammed China's trade policies.

2. Global market overview

U.S. stock markets hit record highs earlier this year and they're not far from those levels right now.

But U.S. stock futures suggest investors want more detail from Trump before they're ready to push shares even higher. The major indexes are holding steady right now.

European markets are mostly edging up in early trading, though the gains are modest.

Asian markets ended the day with mixed results.

A number of blue-chip companies are reporting quarterly results this morning, including General Electric and Procter & Gamble.

3. China growth hits 26-year low

Growth in the China’s gross domestic product (GDP) during 2016 hit its slowest pace in 26 years.

However, fourth quarter numbers showed a 6.8% expansion that beat expectations for it to remain unchanged at 6.7%, suggesting that growth in the world’s second largest economy may have bottomed out.

In other data out Friday in China, December retail sales jumped 10.9%, beating expectation for a 10.7% rise, though industrial production for the same month increased by 6.0%, just below forecasts for a 6.1% advance.

4. Dollar rises but gains limited

The dollar erased losses against other major currencies on Friday, but gains were expected to remain limited until Donald Trump’s inauguration speech, due later in the day.

The greenback found support late Thursday when Federal Reserve Chair Janet Yellen said the central bank should continue to raise interest rates, but slowly.

Speaking at a conference in San Francisco, Yellen said that "allowing the economy to run markedly and persistently ‘hot’ would be risky and unwise," before adding: "I consider it prudent to adjust the stance of monetary policy gradually over time."

But sentiment on the U.S. dollar remained vulnerable ahead of Donald Trump’s inauguration speech amid sustained uncertainty over the new U.S. administration’s fiscal and economic policies.
