Here are five things you must know for Wednesday, Jan. 24:

1. -- Dollar Slides, U.S. Stocks March Higher

U.S. stock futures were higher on Wednesday, Jan. 24, getting a boost from the dollar's decline on global foreign exchange markets.

The U.S. dollar plunged to a fresh three-year low Wednesday after Treasury Secretary Steve Mnunchin told an audience in Davos, Switzerland, that a weakening greenback would be good for American trade. The comments followed a warning from Commerce Secretary Wilbur Ross, who told a panel at the World Economic Forum in the Swiss Alpine village that a decision to slap tariffs on solar panels and washing machines from China and South Korea were the first of more trade measures to come from Washington as Donald Trump accelerates his 'America First' trade policy.

The U.S. dollar index, which benchmarks the dollar against a basket of six global currencies, fell 0.47% to 89.64, the lowest since December 2014.

U.S. stocks ended mixed on Tuesday, Jan. 23, as investors turned their attention to corporate earnings. The Dow Jones Industrial Average fell 0.01% but the S&P 500 and Nasdaq closed at record highs as Netflix Inc. (NFLX) - Get Report jumped 10% after the streaming giant's subscribers surged in the fourth quarter. 

The economic calendar in the U.S. on Wednesday includes the PMI Composite Flash for January at 9:45 a.m. ET, Existing Home Sales for December at 10 a.m., and Oil Inventories for the week ended Jan. 19, at 10:30 a.m.

3. -- iPhone X Estimates Are Slashed 

Apple Inc. (AAPL) - Get Report shares were up 0.2% in premarket trading on Wednesday despite an analyst at JPMorgan Chase & Co. saying that iPhone X demand was weakening.

Analyst Narci Chang slashed iPhone X sales estimates by 33%, and forecast iPhone X production will be down 50% sequentially this quarter.

In a research note, Chang said that "high-end smartphones are clearly hitting a plateau this year."

The note added that the weaker demand would hit the bottom line of European suppliers to the world's biggest tech company.

JPMorgan lowered its rating on AMS AG (AMSSY) , a key supplier which produces optical sensors for smartphones, to neutral from overweight and said that weakness in orders for Apple's flagship iPhone X would likely persist into the second half of the year. AMS shares slumped 6.6% in Frankfurt trading. Other stocks in Apple's European supply chain tumbled, with STMicroelectronics NV (STM) - Get Report falling 3% in Paris and Dialog Semiconductor PLC  (DLGNF) , which is listed in Frankfurt, falling 3.9%.
