Morning Briefing: 10 Things You Should Know

NEW YORK ( TheStreet) -- Here are 10 things you should know for Tuesday, April 23:

1. -- U.S. stock futures were little changed Tuesday after a report showing that growth in China's manufacturing sector may have slowed in April.

The preliminary number for HSBC's Purchasing Managers Index fell to 50.5 from 51.6 in March. A print above 50 indicates expansion. The slowdown in China was blamed on a fall in new export orders, which can be indicative of global demand weakness.

2. -- The economic calendar in the U.S. Tuesday includes new-home sales for March at 10 a.m. EDT.

3. -- U.S. stocks on Monday finished higher.

The S&P 500 gained 0.47% to close at 1,562.50. The Dow Jones Industrial Average added 0.14% to 14,567.17, while the Nasdaq closed up 0.86% to 3,233.55.

4. -- Dzhokhar Tsarnaev, the surviving suspect in the Boston Marathon bombings, told investigators that his older brother, not any international terrorist group, masterminded the deadly attack, a U.S. government source told CNN.

Preliminary interviews with Tsarnaev indicate the two brothers fit the classification of self-radicalized jihadists, the source said, CNN reported.

5. -- Apple ( AAPL), the iPhone, iPad and iPod maker, is expected by analysts to post fiscal second-quarter earnings on Tuesday of $10.04 a share on revenue of $42.38 billion.

The key to Apple's earnings report will be guidance for the June quarter, as the tech giant gets ready to refresh its product lineup, with the oft-rumored iPhone 5S and new iPad and iPad mini tablets.

TheStreet will be live-blogging Apple's earnings on Tuesday beginning at 3:45 p.m. EDT.

6. -- Netflix ( NFLX), the online-entertainment company, posted earnings on Monday that beat Wall Street expectations.

The Los Gatos, Calif.-based company earned 31 cents a share on revenue of $1.02 billion in revenue. Analysts were looking for earnings of 19 cents a share on sales of $1.02 billion.

The company had more than 36 million streaming subscribers at the end of the quarter, up 3.05 million from the previous quarter.

7. -- AT&T ( AT&T), the largest telecommunications company in the U.S., is expected by analysts on Tuesday to post first-quarter earnings of 64 cents a share on revenue of $31.7 billion.

8. -- Chemicals giant DuPont ( DD) reported Tuesday first-quarter earnings that exceeded Wall Street expectations as robust seeds and agricultural chemicals sales helped buffer the impact of softening demand for its titanium dioxide paint pigment.

It also hiked its dividend by 5%.

The company booked earnings of $1.56 a share on revenue of $10.4 billion; analysts were looking for earnings of $1.52 a share on revenue of $10.41 billion.
