Here are five things you must know for Tuesday, Jan. 22:

1. -- Stocks Slump on Global Growth Concerns

U.S. stock futures fell on Tuesday, Jan. 22, and global stocks retreated as investors reacted to warnings on global economic growth.

China's economy grew at its slowest pace in nearly three decades last year, official data indicated Monday, as domestic demand and export growth suffered from government moves to crack down on crippling pollution with tighter rules on building and emissions. The ongoing trade war with the United States also had a knock-on effect through global supply chains, many of which originate from China, the world's biggest exporter.

Confirmation of the China slowdown was followed by the second cut in three months to global growth forecasts from the International Monetary Fund, which cited concerns over unresolved trade conflicts between Washington, Brussels and Beijing and slowing activity in Europe.

The IMF said it sees the world economy growing at 3.5% this year and 3.6% in 2020, clipping 0.2 and 0.1 percentage points, respectively, from its prior estimate.

"After two years of solid expansion, the world economy is growing more slowly than expected and risks are rising," IMF Managing Director Christine Lagarde said. "Does that mean a global recession is around the corner? No. But the risk of a sharper decline in global growth has certainly increased," she said, urging policymakers to brace for a "serious slowdown."

Contracts tied to the Dow Jones Industrial Average fell 182 points, futures for the S&P 500 declined 20.75 points, and Nasdaq futures were down 63.75 points.

Stock markets in the U.S. were closed Monday for Martin Luther King Jr. Day. Last week, the Dow rose 3%, the S&P 500 gained 2.9% and the Nasdaq jumped 2.7%.

The economic calendar in the U.S. Tuesday includes Existing Home Sales for December at 10 a.m. ET.

2. -- J&J, IBM and Travelers Are Highlights of Tuesday's Earnings Calendar

Johnson & Johnson (JNJ) - Get Report posted stronger-than-expected fourth-quarter earnings and forecast a modest increase in full-year sales for 2019 as the consumer healthcare group looks to rebound from last month's steep share price declines triggered by a report that alleged it knew for decades that its iconic baby powder sometimes contained asbestos and failed to alert authorities. The stock fell slightly in premarket trading.

Halliburton Co. (HAL) - Get Report  earned 41 cents a share on an adjusted basis in the fourth quarter, topping Wall Street forecasts by 4 cents. Revenue of $5.94 billion also beat forecasts. Shares rose 0.9%.

Stanley Black & Decker Inc. (SWK) - Get Report earned $2.11 a share on an adjusted basis, 1 cent better than analysts' estimates. Revenue of $3.63 billion topped forecasts of $3.62 billion. The stock fell 0.8% in premarket trading.

Travelers Cos. (TRV) - Get Report reported fourth-quarter adjusted earnings of $2.13 a share, beating forecasts of $2.10.

International Business Machines Corp. (IBM) - Get Report  is expected to report earnings after the closing bell Tuesday.

Jim Cramer said he thinks this week's most important earnings reports might seem like odd ones -- Halliburton and Stanley Black & Decker. They'll be important, Cramer said, because both stocks stand for sectors that have been under real pressure.

Halliburton has a lot to live up to after Schlumberger NV  (SLB) - Get Report reported a quarter with bountiful cash flow and put to rest the notion that its dividend is problematic, according to Cramer.

As for Stanley Black & Decker, its earnings report might settle the issue of how the U.S. housing spend is fairing.

3. -- UBS Profit Misses Estimates Amid Slowdown in Wealth Management  

UBS Group AG (UBS) - Get Report , Switzerland's biggest investment bank, posted weaker-than-expected fourth-quarter earnings because of a slowdown in its key wealth management business.

UBS reported nearly $8 billion in net client outflows from its wealth management division, a figure that echoed record withdrawals from investment funds in the United States and elsewhere, over the final three months of 2018. The exodus helped push net income 2% higher from the same period last year to $862 million but well shy of the bank's own forecast of $985 million. Wealth management profits fell 22% to $769 million, the bank said.

"In wealth management, of course, when I look at our results, they are not up to our expectations or ambitions, but when you look region-by-region in Asia you still see 5% year-on-year growth despite the risk-averse sentiment from clients," CEO Sergio Ermotti told Bloomberg television. "If I look at the U.S., we had net outflows, but if I look at invested assets, we have been performing better than our peers.

"Overall, it's reflective of the sentiment we saw in Q4: less leverage and more people going into cash," he added.

UBS shares traded in the U.S. fell 5% in premarket trading. 

4. -- Starbucks Expands Delivery Service to 6 Additional U.S. Cities

Starbucks Corp. (SBUX) - Get Report  announced Tuesday the expansion of its delivery service pilot to an additional six U.S. cities.

The expansion, in partnership with Uber Eats, begins in San Francisco. Starbucks said it remains on track to bring Starbucks Delivers to nearly one-quarter of its U.S. company-operated stores, with expansion to select stores in Boston, Chicago, Los Angeles, New York and Washington, D.C in the coming weeks. 

Starbucks tested the delivery service in 200 stores in Miami beginning fall 2018.

Later this month, London will be the first European city to trial Starbucks Delivers, the company said.

The coffee giant said about 95% of its core menu items will be available for order using the Uber Eats mobile app. Delivery orders come with an initial $2.49 booking fee.

5. -- France Fines Google $57 Million Under New EU Privacy Law 

A French commission fined Alphabet Inc.'s  (GOOGL) - Get Report  Google about $57 million (€50 million) for an alleged "lack of transparency, inadequate information and lack of valid consent regarding" personalized, or targeted, ads.

The fine came from the regulator known as the National Data Protection Commission, or CNIL. It was the first penalty for a U.S. tech giant under the new European data privacy rules that took effect last year, according to the Associated Press.

The fine against Google also was the biggest regulatory enforcement action since the European Union's General Data Protection Regulation, or GDPR, went into force in May. The rules are aimed at clarifying individual rights to personal data collected by companies, which are required to use plain language to explain what they're doing with it.

Google said in a statement it was "deeply committed" to transparency and user control as well as GDPR consent requirements.

"We're studying the decision to determine our next steps," the company said.
