Stocks went into reverse just before lunchtime on Wall Street Monday. But nobody could figure out why.There weren't any major earnings or economic reports that came out. Yes, there was a big drop in construction spending for December. But it was largely expected. And it was an "old" report whose release was delayed by the government shutdown.Still, the Dow, which was up as much as 130 points shortly after the market opened, was down 400 points by mid-afternoon before cutting those losses nearly in half. The Dow finished the day with a 207-point drop.Boeing, the biggest component of the Dow and the best stock in the blue chip average so far this year, was one of the worst performers, falling nearly 2%. UnitedHealth, McDonald's, Walgreens, Verizon and Nike were among the biggest drags on the Dow too.Paul Nolte, a portfolio manager with Kingsview Asset Management, told CNN Business that he thinks investors are growing tired of talk about an imminent agreement on a trade deal between the United States and China and want more specifics."This is, what the 38th time, that we are 'close' to a trade deal?" Nolte quipped. "You can only cry wolf so many times. We need something more tangible than we're close."Mike O'Rourke, chief market strategist with JonesTrading, told CNN Business he agreed. He said investors may simply be looking for an excuse to sell considering that the Dow, S&P 500 and Nasdaq are all sporting double-digit percentage gains this year."We've gone up sharply on the potential for a deal. But now that the finish line is in sight people are selling the news," O'Rourke said, adding that a pullback is healthy since the"behavior of the past couple of months was atypical."Market slide is much ado about nothingBut Steve Chiavarone, global allocation portfolio manager and equity strategist with Federated Investors, said the sharp pullback Monday is puzzling because most of the economic headlines are still good. He said Monday's sell-off was merely "noise."He pointed out that bond yields have pulled back now that it looks like the Federal Reserve is not going to raise rates again this year. Earnings for the fourth quarter were mostly solid. And if the trade war does end, then the profit picture could improve further.What's more, economists are expecting another solid month of jobs growth when the employment report for February is released Friday.Others argued that investors are just growing nervous for technical reasons, namely that some of the major market indexes have recently topped round number milestones, such as the Dow crossing 26,000 and the S&P 500 passing 2,800."We've tested some of those October and November highs," said William Delwiche, investment strategist with Baird. "It's purely technical and that's probably why we started to see a little loss of momentum."But William Lynch, director of investments at Hinsdale Associates, summed up the mystifying midday move down best."I have no idea why stocks fell. I don't have a clue. I'm as perplexed as you are," he said.Sometimes stocks just go down, especially after they've enjoyed a strong run. It's as simple as that.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company. All rights reserved. 3246

Robert Kraft bought the New England Patriots in 1994 from an owner who wanted to move the team to St. Louis and call them the Stallions."My objective in buying the Patriots is to help bring a championship to New England," Kraft said when he took over the team. Kraft paid 2 million, then a league record, for a team that averaged fewer than seven wins a season and had never won a Super Bowl.Since Kraft bought the team, the Patriots have won the Super Bowl six times under quarterback Tom Brady and head coach Bill Belichick. The trio has been among most successful in the history of professional sports.Kraft has become a titan of pro sports, helping turn the NFL into the country's most valuable league. He is a close friend to President Donald Trump.And the Patriots today are worth .7 billion, the 820

SpaceX completed the last big test of its crew capsule before launching astronauts in the next few months, mimicking an emergency escape shortly after liftoff Sunday.No one was aboard for the wild ride in the skies above Cape Canaveral, just two mannequins. The nine-minute flight ended with the Dragon crew capsule parachuting safely into the Atlantic, after separating and speeding away from the exploding rocket.“I’m super fired up,” Elon Musk, the company’s founder and chief executive, told reporters. “It’s just going to be wonderful to get astronauts back into orbit from American soil after almost a decade of not being able to do so. That’s just super exciting.”NASA astronauts have not launched from the U.S. since the space shuttle program ended in 2011. Musk and NASA Administrator Jim Bridenstine said the next Crew Dragon could launch with a pair of NASA astronauts in the second quarter of this year — as early as April.The Falcon 9 rocket blasted off as normal, but just over a minute into its supersonic flight, the Dragon crew capsule catapulted off the top 12 miles (20 kilometers) above the Atlantic. Powerful thrusters on the capsule propelled it up and out of harm’s way, as the rocket engines deliberately shut down and the booster tumbled out of control and exploded in a giant fireball. The capsule reached an altitude of about 27 miles (44 kilometers) before parachuting into the ocean just offshore to bring the test flight to a close. Everything appeared to go well despite the choppy seas and overcast skies. Within minutes, a recovery ship was alongside the capsule.Recycled from three previous launches, the SpaceX rocket was destroyed as it burst apart in flight and slammed in pieces into the sea. SpaceX normally tries to recover its boosters to drive down launch costs, landing them upright on a floating platform or back at the launch site.NASA’s commercial crew program manager, Kathy Lueders, said the launch abort test was “our last open milestone” before allowing SpaceX to launch Doug Hurley and Robert Behnken to the International Space Station. Their launch date will depend, in part, on whether NASA decides to keep them for months at the orbiting lab, versus just a week or two. A longer mission will require more training before flight.The astronauts monitored Sunday’s flight from the firing room. Hurley said it was “pretty neat to see” the capsule aboard the recovery ship within two hours. By all early accounts, the test was successful.“We’ll see what the data show and go from there,” Hurley said. “But it certainly is a confidence builder from the standpoint if you ever got into that situation, that Dragon can get us away from the booster quickly.”The astronauts also will have access to speed before liftoff. During a launch dress rehearsal Friday, Hurley and Behnken rode in a white Tesla Model X from Kennedy Space Center’s crew quarters to the launch pad, their sleek white and black spacesuits matching the electric sports car with wing-like doors. Musk, who also runs Tesla, used the cars to get around the space center Sunday.Delayed a day by bad weather, Sunday’s launch from Kennedy brought together hundreds of SpaceX, NASA and Air Force employees on land, at sea and in the air. Tourists and locals alike packed the adjoining visitor complex and nearby beaches to see the dramatic fiery spectacle of an out-of-control rocket. Musk brought along his own family, including his brother.NASA hired SpaceX and Boeing a decade ago to transport astronauts to and from the space station for billions of dollars. Both companies struggled with technical problems, adding years of delay and forcing NASA to shell out hundreds of millions of dollars extra for Russian rocket rides.After multiple cargo deliveries for NASA, SpaceX successfully flew an enhanced crew capsule to the space station last March without anyone on board, but it exploded a month later during ground testing. The emergency escape thrusters — the kind used in Sunday’s test — had to be retooled. In all, SpaceX has tested these powerful Super Draco thrusters some 700 times.Last month, meanwhile, Boeing’s Starliner crew capsule ended up in the wrong orbit on its first test flight and had to skip the space station. The previous month, only two of the Starliner’s three parachutes deployed during a launch abort test.Lueders said it’s too soon to know whether Boeing will need to send another Starliner to the space station without a crew or go straight to launching astronauts later this year. An investigation team is still looking into why the Starliner’s automated timer was off by 11 hours during the December test flight.The importance of launch escape was demonstrated in 2017 when two astronauts, an American and a Russian, were pulled to safety during a failed launch from Kazakhstan. They experienced up to seven times the force of gravity during the abort, but walked away from the accident.The SpaceX in-flight abort system, Musk pointed out, should be gentler for the crew and is good from the launch pad all the way to orbit.Musk said the Dragon’s escape system should work — in principle — even if the capsule is still attached when the rocket erupts in a fireball. He said that could look like “something out of ‘Star Wars’” with the capsule flying right out of a fireball.“Obviously we want to avoid doing that,” he quickly added, taking note of all the NASA personnel around him.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Students across the country are spelling their way to greatness in the Scripps National Spelling Bee program. Students are in the process of advancing from classroom to school to region to earn a spot in the national finals in National Harbor, Maryland, in May 2020. Spellers who win their school spelling bee but don’t advance past their region can keep their dream alive of competing in the national spotlight. For the third year in a row, the Bee is offering its RSVBee program. It is a participation pathway that qualifies more spellers for the national finals. It is the only way students living in unsponsored regions can advance and is an additional opportunity for the best spellers in the country to compete on the national stage.The Bee created RSVBee with an eye toward fairness, accessibility, maintaining the integrity of the competition and delivering a quality Bee Week experience for all. The Scripps National Spelling Bee has more than 250 sponsors across the country who support the program and make it possible for local students to advance. Still, there are unsponsored sections in the U.S., and some of its sponsored regions have grown so large and competitive that RSVBee is the Bee’s answer to address access and fairness. “We’ve known for many years that large numbers of excellent spellers have had limited access to the national finals or no pathway at all,” said Paige Kimble, executive director of the Scripps National Spelling Bee. “We created RSVBee to address this very issue and make our iconic competition accessible to a wider population of children who love words and language and enjoy competitive spelling.” The Bee is narrowing the field of the national finals to about 400 competitors, down from last year’s 562, with the intent of providing spellers and their families with a more personalized, quality experience during Bee Week. Parents can apply on behalf of their child for one of about 140 total RSVBee invitations at 1975
