Here are five things you must know for Tuesday, June 11:

1. -- Stock Futures Point to a Sixth Straight Day of Gains

U.S. stock futures rose on Tuesday, pointing to a sixth straight day of gains for Wall Street, despite Donald Trump saying he was ready to levy additional tariffs on China if a trade deal wasn't reached at the G-20 summit later this month.  

The president told CNBC on Monday that he would raise tariffs on China if his Chinese counterpart, President Xi Jinping, didn't attend the G-20 meeting. All indications are that Xi will be at the summit in Japan.

China, for its part, said it would respond firmly if the United States insists on escalating trade tensions.

"China does not want to fight a trade war, but we are not afraid of fighting a trade war," said Chinese Foreign Ministry spokesman Geng Shuang.

"If the United States only wants to escalate trade frictions, we will resolutely respond and fight to the end," he added.

The spokesman wouldn't be drawn on confirming a Xi-Trump meeting at the G-20, saying information would be released once it was available to the ministry, Reuters reported.

Contracts tied to the Dow Jones Industrial Average rose 116 points, futures for the S&P 500 were up 13.30 points, and Nasdaq futures gained 48 points.

The economic calendar in the U.S. on Tuesday includes the Producer Price Index for May at 8:30 a.m. ET.

Earnings reports are expected Tuesday from Dave & Buster's Entertainment (PLAY) - Get Report  and H&R Block (HRB) - Get Report  .

2. -- Tesla Jumps Ahead of Annual Meeting

Tesla (TSLA) - Get Report  was rising 5.4% to $215.52 in premarket trading Tuesday ahead of the electric carmaker's annual shareholder meeting.

Shares jumped more than 4% Monday after Baird analyst Ben Kallo said he believes the selloff of Tesla shares before its rally last week was overblown.

Kallo also said he expects positive news from Tesla at its annual meeting. The firm maintained its $340 price target on the stock.

"Weak demand remains at the forefront as a bear argument, and while it appears Model S+X demand has softened, we continue to believe Model 3 demand is underestimated," Kallo wrote. "Positive updates in recent weeks, including leaked emails and reports of strong deliveries, appear to have improved sentiment on demand, which we view positively."

CEO Elon Musk will lead Tesla's annual meeting Tuesday in Mountain View, Calif., at 5:30 p.m. ET.

"After what has been a brutal six months for Tesla and its shareholders, we expect Tuesday to be a positive event as Musk and the Tesla team showcase the strides they have made so far on production and new Model designs (Model Y on the docket for next year) to further catalyze demand, while also highlighting some of the challenges ahead which they expect to navigate," said Wedbush's Daniel Ives.

3. -- Shutterfly to be Acquired for $1.74 Billion

Shutterfly (SFLY) - Get Report , the digital imaging company, reached a deal to be acquired by private-equity firm Apollo Global Management  (APO) - Get Report for $1.74 billion.

Shutterfly will be bought for $51 a share in cash, a premium of about 1.5% to Shutterfly's closing price on Monday of $50.25. The stock declined 2.2% to $50.01 in premarket trading on Tuesday.

"We look forward to working closely with Apollo as we continue to build a compelling service that enables deeper, more personal relationships for our customers, and to advance our digital and manufacturing capabilities to support sustainable growth," said William Lansing, Shutterfly's chairman.

Apollo also will buy Snapfish, which it plans to combine with Shutterfly to create a bigger player in online-photo services, according to The Wall Street Journal.

The acquisition of Snapfish, which like parent District Photo is closely held, would be contingent on the Shutterfly acquisition closing. District Photo would have a substantial minority stake in the combined company, a person familiar with the matter told the Journal.

Shutterfly also announced Monday it named Ryan O'Hara president and CEO, effective June 24. O'Hara served for more than four years as CEO of Move Inc.

4. -- Intel to Buy Networking Startup Barefoot Networks

Intel  (INTC) - Get Report will buy startup Barefoot Networks as it looks to compete with Broadcom  (AVGO) - Get Report in cloud computing.

Intel called Barefoot Networks "an emerging leader in Ethernet switch silicon and software for use in the data center," and said the deal would support Intel's focus on "end-to-end cloud networking and infrastructure leadership, and will allow Intel to continue to deliver on new workloads, experiences and capabilities for our data center customers."

Intel is the largest chipmaker in the U.S. but it doesn't make chips that manage communications via Ethernet, an area that is dominated by Broadcom.

Intel's acquisition of Barefoot Networks is expected to close in the the third quarter. The terms of the deal weren't disclosed.

Intel rose 2.4% to $47.13 in premarket trading.

Broadcom, meanwhile, jumped 2.6% to $282 after reaching a two-year deal to supply Apple  (AAPL) - Get Report with radio-frequency components for smartphones, tablets and smartwatches.

5. -- House Puts Big Tech on Trial

The House Judiciary Committee on Tuesday will begin its investigation into the market dominance of the technology sector's biggest names, starting with a look at the impact of the companies' platforms on news content, the media and the spread of misinformation online, The Associated Press reported.

The committee last week unveiled a sweeping "top-to-bottom" review of unnamed tech companies, the first such probe by Congress, as reports of a dual effort from the Department of Justice and the Federal Trade Commission to tackle the perceived dominance and potential abuses of tech giants such as Apple, Facebook (FB) - Get Report , Alphabet (GOOGL) - Get Report and Amazon (AMZN) - Get Report .

"These are monopolies," Rep. David Cicilline said on "Fox News Sunday."

Cicilline, a Rhode Island Democrat, will lead Tuesday's subcommittee hearing and said the panel will broadly investigate the digital marketplace and "the dominance of large technology platforms," with an eye toward legislative action to increase competition.

"We know the problems; they're easy to diagnose," Cicilline said. "Shaping the solutions is going to be more difficult."
