NEW YORK ( TheStreet) -- Here are 10 things you should know for Wednesday, Sept. 11:

1. -- U.S. stock futures were pointing to a mostly flat open for Wall Street on Wednesday.

European shares were trading mixed early Wednesday. Asian stocks finished flat. Japan's Nikkei 225 index gained 0.01% and China's Shanghai Composite Index gained 0.2%.

2. -- The economic calendar in the U.S. Wednesday includes wholesale inventories for July at 10 a.m. EDT.

3. -- U.S. stocks on Tuesday gained as China extended a trend of strong economic data and the possibility of a diplomatic resolution over Syria appeared to outpace the likelihood of a military strike.

The S&P 500 gained 0.73% to close at 1,683.99 while the Dow Jones Industrial Average advanced 0.85% to 15,191.06. The Nasdaq added 0.62% to finish at 3,729.02.

4. -- President Obama, in a national address Tuesday night, said diplomacy suddenly holds ''the potential to remove the threat of chemical weapons'' in Syria without the use of force. But he also vowed the U.S. military will be ready to strike against President Bashar Assad if other measures fail.

Obama said, for now, he has asked congressional leaders to postpone a vote on legislation he has been seeking to authorize the use of military force against Syria.

The president offered reassurances that even the failure of diplomacy -- in promised talks at the U.N. or elsewhere -- would not plunge America into another war.

''I will not put American boots on the ground in Syria,'' he promised in his 16-minute speech. ''I will not pursue an open-ended action like Iraq or Afghanistan. I will not pursue a prolonged air campaign like Libya or Kosovo.''

''This would be a targeted strike to achieve a clear objective: deterring the use of chemical weapons and degrading Assad's capabilities,'' he said.

5. -- Apple ( AAPL - Get Report) unveiled its latest iPhone hardware on Tuesday, launching its new iPhone 5s and 5c offerings at the company's headquarters in Cupertino, Calif.

Apple's shares had run up in anticipation of the news, but in keeping with the company's recent launches, sold off following the announcement. The tech giant's stock closed down 2.28% on Tuesday to $494.64. The stock was trading lower in premarket trading Wednesday

Described as the "most forward thinking phone ever," by Phil Schiller, Apple's senior vice president of worldwide marketing, the 5s contains a new 64-bit A7 chip and M7 "motion coprocessor" which eases the burden on the A7 for better power efficiency.

The iPhone 5s will be available in the U.S. on Sept. 20. The 16GB model is priced at $199, while the 32GB and 64 GB models are priced at $299 and $399, respectively.
