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

1. -- U.S. stock futures were rising as investors await durable goods data and hang on to hope for a more final Greek debt deal.

European stocks rose on Tuesday after Greece offered concessions to its international creditors at an emergency summit, stoking hopes of a debt deal within the next two days. The Athens Composite Index jumped 3.75%, and the German DAX and French CAC 40 were each up 1%.

Asian stocks rose, as Japan's Nikkei 225 index hit a 15-year high, helped by a falling yen against the dollar. The Topix also strongly rose. Hong Kong's Hang Seng and China's Shanghai Composite also both bounced upward.

2. -- The economic calendar in the U.S. on Tuesday includes durable goods order data at 8:30 a.m., the comparable store sales Redbook at 8:55 a.m., the Federal Housing Finance Agency house price index at 9 a.m., the Purchasing Managers' Manufacturing Index Flash at 9:45 a.m., new home sales data at 10 a.m., and the Richmond Fed Manufacturing Index at 10 a.m.

3. -- U.S. stocks on Monday rose as investors expressed palpable relief at a prospective Greek debt deal. 

The Dow Jones Industrial Average (DIA) rose 0.58% to 18,119.78. The S&P 500 (SPY) closed up 0.61% to 2,122.85. The Nasdaq (QQQ) jumped 0.72% to 5,153.97.

4. -- Software maker Oracle (ORCL) is expanding its cloud offerings, said its founder and Executive Chairman Larry Ellison. The move means Oracle is competing more directly with Amazon (AMZN). In a webcast, Ellison mentioned that Oracle would compete with Amazon on price.

Amazon Web Services is the largest cloud provider, followed by competitors Microsoft (MSFT) and IBM (IBM). The new Oracle offering is called Oracle Cloud Platform.

In premarket trading, Oracle was rising by 0.31%. Amazon was up 0.28%.

5. -- After the eurozone countries agreed to extend emergency financing to Greece on Monday, Greek Prime Minister Alexis Tsipras will need to find ways to appease the euro member states with reforms that will satisfy the country's creditors. On Tuesday, the European Central Bank agreed to additional emergency financing for Greece as well, according to reports.

Yet big issues remain to be resolved, as Greece is being asked to make concessions on pensions, the sales tax rate and other sticking points. Any deal requires the approval of a resistant Greek parliament.

Investors were hopeful for a resolution, boosting the Athens Stock Exchange General Index by 9% on Monday.

6. -- Chinese online company Alibaba (BABA) will join with its related company Ant Financial to invest a total of about $1 billion in Koubei, a food-ordering and delivery app. The move will help Alibaba more directly compete with Tencent (TCEHY), which runs China's popular food-ordering app Ele.me.

Alibaba is targeting the "O2O" market, or online-to-offline, in which apps allow users to order real-life services or goods electronically. The investment will likely also boost Alibaba's online payments platform, which is one of the biggest parts of its business.

In premarket trading, Alibaba was up 0.42%.

7. -- Swiss agricultural products company Syngenta (SYTagain rejected a $45 billion takeover offer from Monsanto (MON), saying that Monsanto's bid was unsatisfactory. The deal would also likely run into trouble with regulators, Syngenta said. However, Syngenta did say that it wasn't opposed to a takeover offer if it would satisfy shareholders. In a video, Syngenta Chairman Michel Demare said the current offer undervalued the company and presented few synergies to entice shareholders.

Monsanto's offer was at a 43% premium to Syngenta's pre-offer share price, but Syngenta says that's too low given how currency exchange and emerging market prices have made the company look shakier than it is.

Syngenta reports earnings Tuesday.

8. -- A privacy group filed a complaint with the Federal Trade Commission claiming that citizen taxi company Uber's new privacy policy would allow the company to track customers even when they weren't on rides. If the GPS locator is running on a mobile phone, Uber could continue to track the user's location, the complaint said.

Uber has run into privacy problems before when it tracked the location data of journalists reporting on the company.

Meanwhile, a California ruling that Uber would need to treat its drivers as employees, not contractors, might not be terribly detrimental to the company, an Uber investor told Reuters. Although the ruling might hurt Uber's valuation, the company is established enough that it could pay lower wages to drivers, satisfy employment requirements and still make a profit, the investor said.

9. -- Big-box store Wal-Mart (WMTrenewed its contract with Green Dot (GDOT) to manage its prepaid debit cards. The deal will span five years and will allow Green Dot to run Visa (V) and Mastercard (MA) branded cards for Wal-Mart.

Green Dot shares rose 29.7% in premarket trading on the news of the deal.

10. -- Earnings results include Blackberry (BBRY), Carnival (CCL), Darden Restaurants  (DRI) and IHS  (IHS), all before the opening bell.
