Here are five things you must know for Wednesday, Sept. 13:

1. -- U.S. stock futures pointed to a weak start for Wall Street on Wednesday, Sept. 13, after the three major U.S. indexes closed at record highs during the previous trading session.
 
Stocks jumped on Tuesday, Sept. 12, as the promise of tax reform from the Trump administration fueled gains in the financials sector. 

The Dow Jones Industrial Average gained 0.28% to finish at a new high of 22,118.86. The S&P 500 gained 0.34%, settling at a new record high of 2,496 after an all-time closing high a day earlier. The Nasdaq also notched a new record, its first since Sept. 1, after rising 0.34% to 6,454. 

"Financial markets seem to have abruptly stopped worrying about the end of the world, with stocks soaring again, bond yields pushing higher, and safe haven currencies such as the JPY selling off," said Rob Carnell, Asia head of research at ING, in a note. "It won't last. But until the next risk-off event appears, we might as well enjoy it and can focus back on the underlying macro story."

The economic calendar in the U.S. for Wednesday includes the Producer Price Index for August at 8:30 a.m. ET, and Oil Inventories for the week ended Sept. 8, at 10:30 a.m.
 
Earnings reports are expected from Cracker Barrel Old Country Store Inc. ( CBRL) and United Natural Foods Inc.  ( UNFI) .
 
2. -- Apple Inc. ( AAPL)  shares listed in Germany declined by 2.5% and U.S. shares fell 0.64% in premarket trading on Wednesday as investors reacted to news that the tech giant's new $1,000 iPhone X won't launch until the new fiscal year.

Sales of the new anniversary iPhone edition likely will begin in early November, well in time for the peak of the U.S. holiday shopping season but still likely to push a good portion of the phone's revenue into the December to March quarter, the second of the company's next financial year.

"Apple is hoping the later availability date for iPhone X will not affect iPhone 8 sales this quarter," said IHS Markit in a research note. "Apple's lower iPhone 8 pricing should limit the impact, but it remains a risk. iPhone X is the future of smartphone design, but it's also available in the future too."

On Tuesday, Apple unveiled the state of the art iPhone X as well as its new iPhone 8 and iPhone 8 Plus models. The iPhone 8 and 8 Plus will be released at the end of September.

Apple's iPhone X boasts an all-glass edge-to-edge display with no home button. The phone comes equipped with all new facial recognition software, called Face ID, which can both unlock the device and process payments.
 
The phone also comes with a 12MP dual-lens cameras optimized for augmented reality, and a customization emoji software called Animoji that can mimic users' expressions.
 
The iPhone X will also boast wireless charging, and give fans of photography portrait mode in both the front and rear cameras.
 
The X comes in both 64GB and 256GB models, and will begin at $999. Customers can order the phone starting Oct. 22 and it will begin to ship on Nov. 3.

3. -- Bitcoin prices fell below $4,000 mark for the first time in a month on Wednesday as investors continued to dump the cryptocurrency following a clampdown on cryptocurrencies in China and accusations of fraud from one of Wall Street's most influential bankers.

Bitcoins were marked at $3,966 each on the Bitsmap exchange in London, the lowest since Aug. 13 and down about 5% from Tuesday night's levels following a series of disparaging comments from JPMorgan Chase & Co. (JPM) CEO Jamie Dimon, who called the virtual currency concept a "fraud" and said he'd fire any of his traders for dealing in it. So far this month, however, bitcoin prices have fallen nearly 20%, or more than $1,000, from the all-time peak the virtual currency reached on Sept. 1.

"The currency isn't going to work," Dimon told the Delivering Alpha investor conference in New York. "You can't have a business where people can invent a currency out of thin air and think that people who are buying it are really smart."

"My daughter bought a bitcoin and it immediately went up, now she thinks she's a genius," Dimon said.

"It's just not a real thing," Dimon said. "Eventually, it will be 'the emperor has no clothes.'"
