  • iStock/Thinkstock(NEW YORK) -- The U.S. stock market, which has lost more than $3 trillion in the last 15 days, ended the week with a dramatic late-day rally in which the Dow Jones Industrial Average finished up 331 points after tripping and falling more than 500 points earlier in the session.The Dow gave traders a whipsaw day with a series of stomach-churning nosedives and precipitous spikes before bargain hunters moved in during the final two hours of trading and sent the market soaring into the closing bell.The Dow closed up 1.38 percent to 23,190.The other major indexes also traded up. The S&P 500 jumped 38 points to close at 2,641, and the Nasdaq vaulted 97 points to 6,874, up 1.44 percent from the previous day.It was only the second day in the past six trading days that the Dow finished in the green. Friday's rally came a day after the Dow tumbled 1,032 points. The week started with the index sinking a record 1,175 points.Overall, the Dow ended the week down 5 percent.Since the Dow hit a record high of 26,616 on Jan. 26, the U.S. stock market has lost a whopping $3.1 trillion, Yousef Abbasi, global market strategist for JonesTrading, told ABC News.The seesaw day on the market came after the Asian and European markets both closed in negative territory. Japan's Nikkei 225 fell 508 points, or 2.32 percent, to 21,382, and China's Shanghai composite sank 4.02 percent to 3,130. The Pan-European STOXX 600 was off .70 percent and Britain's FTSE was down 34 points, or .49 percent.The Dow and S&P 500, which also soared to a record high of 2,872 on Jan. 26, have both pulled back more than 10 percent in the past two weeks, thrusting the market into a full correction.Fueling the topsy-turvy market have been indications of inflation on the horizon, including whether rising wages and an increase in the number of jobs added to the economy will prompt the U.S. Federal Reserve to accelerate a rise in interest rates."It's always encouraging when you end the week on an up note and you see buying into the close," Randy Frederick, vice president of trading and derivatives for Charles Schwab, told ABC News.But Frederick said he was still jittery about the market, citing a key indicator of volatility. He said the CBOE Volatility Index, also known by its ticker symbol VIX, closed at 29.06, way above its long-term average of 19.5."I'm not convinced this is over yet," Frederick said of turbulence in the market. "We're still looking at some sizable movement in the market in the coming days."

  • Justin Sullivan/Getty Images(NEW YORK) -- Apple's newest product, a smart speaker called HomePod, hit stores today and the reviews are generally positive.The HomePod was set for a December 2017 release, but Apple delayed it to 2018, saying that it needed more time to perfect it.Priced at $349, it's much more expensive than the Amazon Echo and Google Home, which are roughly a third of the price.Apple CEO Tim Cook introduced the HomePod at a keynote address in June 2017, saying that it would "reinvent home music."The Hardware"The music quality is second to none."The HomePod comes in two colors -- white and space gray -- and features a high-excursion woofer with a custom amplifier."HomePod is a premium speaker with much better music and sound quality than the Amazon and Google alternatives," Jim Martin, editor of Tech Advisor, a site that covers consumer technology, told ABC News.Jim Dalrymple, an Apple expert at Loop Insights, a tech news site, said he was "pleasantly surprised by how well the music in the room seemed to just kind of envelope you.""The music quality is second to none," he added. "Music is the reason I would buy HomePod."The HomePod uses spatial awareness to adjust the audio accordingly."I've heard the Echo and, to be honest, it kind of sounded like music from a tin box," said Dalrymple. "Any speaker can blast music but the "HomePod puts music around the room."The six microphones built into the device lets Siri hear a user even from a distance.Dalrymple claims the HomePod responded to his voice from at least 20 feet away.A waveform display appears at the top of the cylinder base, letting a user know that Siri is listening, and it doubles as a control pad.Built with an A8 chip that acts as the brain of the speaker, the HomePod easily transforms from speaker to home assistant.The Intelligence"I think Siri could be expanded."Siri can send messages, give news updates, check the weather and control smart devices that are synced with the HomePod and other Apple products, the same features of the Amazon Echo and Google Home.But it could do more."I think Siri could be expanded and will be in the future," said Dalrymple. "I would like to see Siri do more in the Apple ecosystem so I could control things like the calendar.""HomePod is an Apple-only device, so it is much more limited in what it can control in terms of smart home gadgets," said Martin."It won't work with Android at all," he added, noting that Amazon's and Google's devices can.And the HomePod won't play music from popular streaming services like Pandora or Spotify.It exclusively plays tunes from Apple's own music subscription service, Apple Music, which costs $10 a month and offers over 45 million songs."[You] really need an Apple Music subscription to make the most of Siri's capabilities," said Martin.However, there's a way to get another music streaming service to play through the HomePod."You can play any music or audio through the HomePod from your iPhone or iPad via AirPlay," said Martin. "So it can play Spotify without the deep integration and control with Siri."Both experts agree that the HomePod is a powerful music player, but it still has some kinks that Apple could fix in future models.Copyright © 2018, ABC Radio.

  • Alexander Hassenstein/Getty Images(PYEONGCHANG, South Korea) -- Thousands of drones were used to put on a light show during the opening ceremony for the 2018 Winter Olympics in Pyeongchang, South Korea, Friday morning for the first time, according to Intel, which is overseeing the event.A total of 1,218 drones outfitted with LED lights were used to paint a "colorful illustration in the sky," setting a new Guinness World Record on the number of drones flown at the same time, according to an Intel spokeswoman. Intel holds the current record after 500 drones were flown simultaneously for a light show in Krailling, Germany, on Oct. 7, the spokeswoman said.The drones are controlled through an automated software program, though they do have one pilot for backup, Intel said.In addition to the opening ceremony, the drones will be used throughout the games, creating light-filled formations every night from Feb. 10 -24 during the nightly victory ceremonies."It's something that we wanted to integrate that experience into the Olympics on a daily occasion, because not everyone is going to be at the opening ceremony, and we want to give everyone in Korea a chance to see these shows," said Natalie Cheung, the general manager for Intel's drone light shows.An athlete on a snowboard; a bird of prey in flight; and, of course, the five interlaced Olympic rings are among the aerial illustrations that viewers can anticipate seeing during the shows.The drones are lightweight and are the only ones of their kind, built specifically for outdoor light shows, according to Intel.Because Intel's drones had never flown in such cold temperatures, members of the drone light show team ventured to the Alps to test how they would operate in minus 10-degree Celsius weather."We were a little bit more creative about this," Cheung said. "We changed our operations so that we had literally minutes for us to bring the drones outside the temperature-controlled room into the fields so we could fly. We needed to make sure the batteries were warm enough so the drones could fly."Intel is the official drone partner of the Olympics.
