NEW YORK (TheStreet) -- Here are 10 things you should know for Tuesday, July 29:

1. -- U.S. stock futures were up Tuesday across the indices, as investors geared up for a major earnings day and applauded Monday's news of mergers like that of Zillow and Trulia .

European stocks were slipping Tuesday, as investors looked for safety from the conflict in Ukraine and sanctions against Russia.

2. -- The economic calendar in the U.S. on Tuesday includes earnings reports from 346 companies, Marriott , Coach , Merck and Twitter among them. An update from the Case-Shiller Home Price Index will arrive today. Investors are preparing for this week's Federal Reserve policy announcement and second-quarter GDP figures on Wednesday and July government jobs report on Friday.

3. -- U.S. stocks on Monday were mixed, on news of Dollar Tree buying out Family Dollar for $8.5 billion, and rumors that U.S.-based Hospira was in talks to buy out French yogurt-maker Danone's medical and nutritional business.

The Dow Jones Industrial Average closed up 0.13% to 16,982.59. The S&P 500 rose 0.03% to 1,978.91. The Nasdaq sank 0.1% to 4,444.91. 

4. -- Inversion, the newly popular practice in which U.S. companies buy foreign competitors in order to reincorporate offshore and save on taxes, is in the headlines again. Yesterday U.S. injectable drug maker Hospira was reported to be in talks with French yogurt-maker Danone to buy Danone's medical and nutritional business for about $4 billion -- and possibly to save on the tax bill.

Jamie Dimon of JPMorgan Chase defended the practice, which the New York Times said will reap nearly $1 billion in fees for banks involved in the transactions. "You want the choice to be able to go to Walmart to get the lowest prices," Dimon said in a conference call with reporters. "Companies should be able to make that choice as well."

5. -- U.K. oil company BP warned that more oil sanctions in Russia could affect the company's bottom line. BP is the foreign oil company with the largest investment in Russia, and it holds a 20% share of OAO Rosneft, a Russian oil company.

BP reported a rise in second-quarter profit of 34%, with earnings of $3.6 billion -- up from $2.7 billion a year ago. The earnings beat estimates. BP did warn, though, that its production will likely be less in the third quarter due to maintenance.

6. -- The European Union will impose $50 billion in fines on Russia for its takeover of oil company Yukos, which a court in the Hague ruled to be illegal on Monday. However, the fine may be difficult to collect.
