After decent rally, perhaps time for a pause

NEW YORK (Reuters) - Stocks could struggle to extend their seven-week winning streak as the quarterly earnings period draws to a close and the market bumps into strong technical resistance.

Many analysts say the market could spend the next few weeks consolidating gains that have lifted the benchmark Standard & Poor's 500 <.spx> by 6.6 percent since the start of the year.

The S&P 500 ended up 0.1 percent for the week, recovering from a late sell-off on Friday after a Bloomberg report about slow February sales at Wal-Mart triggered a slide in the retailer's shares. It was the index's seventh week of gains.

Odds of a pullback are increasing, with the market in slightly overbought territory, said Bruce Zaro, chief technical strategist at Delta Global Asset Management in Boston.

"I do suspect the closing of the earnings season will lead to at least a pause and possibly a pullback," Zaro said. The S&P 500 could shave 3 to 5 percent between now and early April, he said.

Fourth-quarter earnings have mostly beaten expectations. Year-over-year profit growth for S&P 500 companies is now estimated at 5.6 percent, up from a January 1 forecast for 2.9 percent growth, and 70 percent of companies are exceeding analyst profit expectations, above the 62 percent long-term average, according to Thomson Reuters data.

On Thursday, Wal-Mart, the world's largest retailer, is due to report results, unofficially closing out the earnings period. Investors will be keen to see its quarterly numbers, especially after the Friday's news report that rattled investors.

The S&P 500 has gained 4.3 percent since Alcoa kicked off the earnings season on January 8.

The approaching March 1 deadline for across-the-board federal budget cuts unless Congress reaches a compromise adds another reason for caution, especially with recent economic data indicating the recovery remains bumpy.

Manufacturing output fell 0.4 percent last month, the Federal Reserve said on Friday, but production in November and December was much stronger than previously thought.

TESTING RESISTANCE

The S&P 500 has been trading near five-year highs, and it notched its highest level since November 2007 this week. But the gains have pushed the benchmark index almost as far as it is likely to go in the near term, with strong resistance hovering around 1,525 and 1,540, one analyst said.

As a result, the index is set to move sideways, said Dave Chojnacki, market technician at Street One Financial in Huntington Valley, Pennsylvania. "We just don't have the volume or the catalyst right now" to go above those levels, he said.

At the same time, other analysts say, the market has not shown significant signs of slowing, including a break below 15- and 30-day moving averages.

Such moves would be needed to show that momentum is slowing or that the market is at risk of a correction, said Todd Salamone, director of research for Schaeffer's Investment Research in Cincinnati, Ohio. The S&P 500's 14-day moving average is at 1,511 while the 30-day is at 1,494. The index closed Friday at 1,519.

Recent M&A activity, including news this week of a merger between American Airlines and US Airways Group , helped provide some strength for the market this week and optimism that more deals may be on the way.

In the coming days, the market will focus on minutes from the latest Federal Reserve meeting, due to be released on Wednesday, which could provide support if they suggest the Fed will remain on its current course of aggressive monetary easing.

The Fed minutes released in January spooked markets a bit when they revealed that some Fed officials thought it would be appropriate to consider ending asset purchases later in 2013. U.S. Treasury yields rose on that news, though market worries about a near-term end to quantitative easing have since faded.

Among other companies expected to report earnings next week are Nordstrom , Hewlett-Packard and Marriott International

The Saturday Profile: Mary Beard, Classics Professor, Battles Internet Attacks

JANUARY was a busy month for Mary Beard, a Cambridge academic who is the closest thing, if it exists, to a celebrity classics professor.

In just a few weeks, Ms. Beard, who has helped popularize the study of antiquity through television and a lively blog, “A Don’s Life,” turned 58; finished a draft of her book on Roman laughter; became an officer of the Order of the British Empire; and attended the funeral of a lifelong friend and editor, Peter Carson.

But little could have prepared her for the furor she faced after she appeared on a weekly BBC debate show last month and, while discussing immigration, expressed the unpopular view that Britain’s social services would not be overburdened when restrictions on Bulgarian and Romanian movement around Europe are lifted next year.

Her remarks, made on Jan. 17, unleashed a torrent of vicious, crude and personal online attacks, many targeting her unadorned style and her long, unkempt gray hair. Anonymous attackers also superimposed a picture of her face on a pornographic image. But rather than retire to her fainting couch (it is in her Newnham office, should she need it), or accept what happened as the cost of being a public figure in the Internet age, Ms. Beard decided to fight back.

Adopting what she said was a “high-risk strategy,” Ms. Beard reproduced on her blog some of the most unsavory remarks and the mocked-up image, which she has since removed.

“I wanted people to see how bad it is,” she said in an interview at Cambridge’s Newnham College, which she attended and where she has taught for nearly 30 years. “You never know what it’s like, because no mainstream paper will print it, nobody on the radio will let you say it, and so it came to look as if I was worried that they said I hadn’t done my hair.

“What was said was pornographic, violent, sexist, misogynist and also frightfully silly,” she said.

The comments would prove fatal for “Don’t Start Me Off,” an off-color online forum that became a bulletin board for her worst abusers. The site was eventually shuttered by its moderator, Richard White, who, in an about-face unexpected from an online provocateur, sent Ms. Beard a lengthy apology.

“I am genuinely sorry for any upset I may have caused you,” he wrote her privately. “I say this not because I’ve been ‘rumbled’ or because I think it’ll help my cause, but because it’s the right thing to do.”

Peter Stothard, the editor of The Times Literary Supplement, which publishes Ms. Beard’s blog, said her response was a quintessential case of “Mary being Mary.”

“She dealt with it in an extraordinary way,” Mr. Stothard said. “I don’t think it was necessarily bound to work, but it seems that it did. It’s a rare victory.”

The blog, which usually gets between 20,000 and 25,000 hits a week, drew about 85,000 visitors the week she addressed the controversy.

AT first glance, the professor is an unlikely candidate for such impassioned attention. Her gray hair, which she described as “mad,” hangs around her shoulders, which might be draped in a loose-fitting sweater or dress. She often uses tights to display a hint of her personality: on a recent Friday, they were black and adorned with shining plastic stars.

“I’ve chosen to be this way because that’s how I feel comfortable with myself,” Ms. Beard said. “That’s how I am. It’s about joining up the dots between how you look and how you feel inside, and I think that’s what I’ve done, and I think people do it differently.”

Ms. Beard first grew interested in classics as a precocious teenager with a talent for Latin and Greek and a taste for archaeological digs, where days spent excavating usually ended at the local pub, she said. But she would become a classics star at Cambridge, which was mostly male when she first showed up as a student in 1973. Now one of the university’s most high-profile professors, she extended her reach to a nation when “Meet the Romans with Mary Beard,” a short series, was first shown on BBC 2 last spring.

In three episodes, Ms. Beard appears as the viewer’s excitable and well-read guide to ancient Rome. She bikes around the city, perches atop ruins, pulls Roman artifacts out of storerooms and explains that a strange-looking tomb monument was built to recall a Roman bakery, a description that makes both bakeries and monuments seem fascinating.

“Classics isn’t about the ancient world. It’s partly about the ancient world, but it’s about our conversation. It’s how we try to talk to antiquity,” she said, elaborating on her mission to bring the subject to the masses. “A lot of people will always say, ‘I really know nothing about the ancient world.’ But there’s lots and lots of things people know. Partly they’ve been encouraged to think they’re ignorant about it. In some ways, the job to do is show people that they know much more than they’d like to admit.”

“Meet the Romans” showcased Rome, but it also put Ms. Beard’s appearance on display. When the show first aired, the Sunday Times critic A. A. Gill suggested she “really should be kept away from cameras altogether.” Since then, British columnists have debated whether her style is the result of laziness and inattention or unwillingness to conform to traditional standards of beauty.

NOT easily dissuaded, Ms. Beard is in talks for another Rome-based show. That is in addition to her typical agenda, filled with books to write, classes to teach and lectures to prepare.

Ms. Beard joined The Times Literary Supplement as its classics editor in 1992, eight years after writing her first book. She has since published more than a dozen; the most successful, “The Fires of Vesuvius: Pompeii Lost and Found,” was published in the United States in 2010. But Ms. Beard admits that the first time anyone ever heard of her was after the attacks of Sept. 11, 2001, when she wrote in The London Review of Books that some felt America “had it coming.”

The remarks drew global criticism. Though she does not regret them, Ms. Beard said she would choose different words now.

“Thinking back to then, what I wanted to say I would still want to say, which is that ghastly acts of terrorism are not unconnected to Western foreign policy,” in Britain as well as the United States, she said. “If I was making that point now, I wouldn’t write in those words; I would say something much more like what I just said.

“What politicians do is they never get the rhetoric wrong, and the price they pay is they don’t speak the truth as they see it,” she said. “Now, I will speak truth as I see it, and sometimes I don’t get the rhetoric right. I think that’s a fair trade-off.”

Ms. Beard is called “wickedly subversive” on her blog. It is a phrase routinely cited when she comes up in British newspapers, but, looking slightly embarrassed, she insists it was an editor’s choice, not hers.

“I’m always keen on understatement, you know?” she said with a laugh. “I’d just put ‘classicist.’”

Molly Sims: I Nursed a Little Vampire!

Mom & Babies
Celebrity Baby Blog

02/15/2013 at 01:00 PM ET

Following the birth of her baby boy, Molly Sims was ready to sink her teeth into breastfeeding.

The only problem? Her son Brooks Alan had beaten her to it.

“Early on in the hospital, they really want you to breastfeed, so I’m trying everything,” the model mama, 39, shared during a Wednesday appearance on Anderson Live.

“And I’m like, ‘Gosh, this really, really hurts.’ And they’re like, ‘Oh, we know.’”

Determined to find the root of the pain, Sims went searching in her newborn’s mouth — and was shocked at her discovery.

“I’m like, ‘Is there any way a baby could be born with a tooth?’” she recalls. “And they went, ‘Oh sweetie, I know you’re a model, but … babies aren’t born with teeth!’”

She continues: “Come to find out, my baby was born with a tooth!”

Courtesy ANDERSON LIVE

Despite countless attempts to successfully nurse — “I did nipple shields, nipple guards, supplemental nursing system, it was horrible,” the new mom says — Sims eventually decided to call it quits.

“He was literally like a vampire on me for three months — it was unbelievable,” she says with a laugh. “Cut to I’m not breastfeeding and I’m proud of it.”

Now Brooks, 7 months, has moved on to other milestones — including crawling — and is already taking after his dad, Scott Stuber.

“He has the hairline of my husband. It’s like an Eddie Munster kind of hairline. It’s not so attractive, but [he'll] end up growing into it,” Sims says.

American Idol's Top 40 Revealed

TV Watch

American Idol

By Steve Helling

02/14/2013 at 10:00 PM EST

From left: Randy Jackson, Mariah Carey, Ryan Seacrest, Nicki Minaj and Keith Urban

Michael Becker/FOX.

American Idol really, really wants a woman to win this season. At the beginning of Thursday's episode, they reminded us that a female singer hasn't won the show since 2007, when Jordin Sparks bested Blake Lewis for the top prize. Let's put this into perspective: The last time a woman won, George W. Bush was still president, J.K. Rowling was still writing the Harry Potter series, and no one had any idea who Snooki was. Well, maybe a few people knew her.

After Ryan Seacrest all but begged us to vote for a female, we finally got to see the level of the women's talent. Angela Miller sat at the piano and sang her own song, "You Set Me Free." It was a show-stopping performance, prompting judge Keith Urban to rave.

"If that was recorded right there, I would play it in my car," he said. "That was just a beautiful song."

Miller was followed by Candice Glover, who gave an strong version of Alicia Keys's "Girl on Fire." Janelle Arthur also impressed with a pleasant version of Carrie Underwood's "I told You So."

Shubha Vedula had the nerve to sing a Mariah Carey song in front of Mariah Carey and did a great job.

And then there was Zoanette Johnson. (At some point, she needs to drop her last name and just be known as Zoanette.) She played the drums as she sang a song she had improvised onstage the previous night. It was a rambling tune about her Idol experience. It was manic and baffling. And then she came to an abrupt stop and yelled at the background singers.

"Slow it down! C'mon guys," she pleaded. "I need this to be right." At some point, she lost a drumstick.

It's fun to imagine what Simon Cowell's reaction would be to her performances.

Kez Ban, the season's other memorable contestant, was quickly cut from the competition after singing her original song. There is clearly only room for one unpredictable contestant this season – and her name is Zoanette.

As the show wound down, the judges cut the field down to 20 women, and then brought in the remaining 28 male singers to cut them down to 20. That's when the judges had Josh Holiday sing "Georgia on My Mind." He split his pants from crotch to knee.

But Holiday and 39 others are season 12's top 40. One of them will be the next American Idol. Will it be a girl?

Study: Fish in drug-tainted water suffer reaction

BOSTON (AP) — What happens to fish that swim in waters tainted by traces of drugs that people take? When it's an anti-anxiety drug, they become hyper, anti-social and aggressive, a study found. They even get the munchies.

It may sound funny, but it could threaten the fish population and upset the delicate dynamics of the marine environment, scientists say.

The findings, published online Thursday in the journal Science, add to the mounting evidence that minuscule amounts of medicines in rivers and streams can alter the biology and behavior of fish and other marine animals.

"I think people are starting to understand that pharmaceuticals are environmental contaminants," said Dana Kolpin, a researcher for the U.S. Geological Survey who is familiar with the study.

Calling their results alarming, the Swedish researchers who did the study suspect the little drugged fish could become easier targets for bigger fish because they are more likely to venture alone into unfamiliar places.

"We know that in a predator-prey relation, increased boldness and activity combined with decreased sociality ... means you're going to be somebody's lunch quite soon," said Gregory Moller, a toxicologist at the University of Idaho and Washington State University. "It removes the natural balance."

Researchers around the world have been taking a close look at the effects of pharmaceuticals in extremely low concentrations, measured in parts per billion. Such drugs have turned up in waterways in Europe, the U.S. and elsewhere over the past decade.

They come mostly from humans and farm animals; the drugs pass through their bodies in unmetabolized form. These drug traces are then piped to water treatment plants, which are not designed to remove them from the cleaned water that flows back into streams and rivers.

The Associated Press first reported in 2008 that the drinking water of at least 51 million Americans carries low concentrations of many common drugs. The findings were based on questionnaires sent to water utilities, which reported the presence of antibiotics, sedatives, sex hormones and other drugs.

The news reports led to congressional hearings and legislation, more water testing and more public disclosure. To this day, though, there are no mandatory U.S. limits on pharmaceuticals in waterways.

The research team at Sweden's Umea University used minute concentrations of 2 parts per billion of the anti-anxiety drug oxazepam, similar to concentrations found in real waters. The drug belongs to a widely used class of medicines known as benzodiazepines that includes Valium and Librium.

The team put young wild European perch into an aquarium, exposed them to these highly diluted drugs and then carefully measured feeding, schooling, movement and hiding behavior. They found that drug-exposed fish moved more, fed more aggressively, hid less and tended to school less than unexposed fish. On average, the drugged fish were more than twice as active as the others, researcher Micael Jonsson said. The effects were more pronounced at higher drug concentrations.

"Our first thought is, this is like a person diagnosed with ADHD," said Jonsson, referring to attention deficit-hyperactivity disorder. "They become asocial and more active than they should be."

Tomas Brodin, another member of the research team, called the drug's environmental impact a global problem. "We find these concentrations or close to them all over the world, and it's quite possible or even probable that these behavioral effects are taking place as we speak," he said Thursday in Boston at the annual meeting of the American Association for the Advancement of Science.

Most previous research on trace drugs and marine life has focused on biological changes, such as male fish that take on female characteristics. However, a 2009 study found that tiny concentrations of antidepressants made fathead minnows more vulnerable to predators.

It is not clear exactly how long-term drug exposure, beyond the seven days in this study, would affect real fish in real rivers and streams. The Swedish researchers argue that the drug-induced changes could jeopardize populations of this sport and commercial fish, which lives in both fresh and brackish water.

Water toxins specialist Anne McElroy of Stony Brook University in New York agreed: "These lower chronic exposures that may alter things like animals' mating behavior or its ability to catch food or its ability to avoid being eaten — over time, that could really affect a population."

Another possibility, the researchers said, is that more aggressive feeding by the perch on zooplankton could reduce the numbers of these tiny creatures. Since zooplankton feed on algae, a drop in their numbers could allow algae to grow unchecked. That, in turn, could choke other marine life.

The Swedish team said it is highly unlikely people would be harmed by eating such drug-exposed fish. Jonsson said a person would have to eat 4 tons of perch to consume the equivalent of a single pill.

Researchers said more work is needed to develop better ways of removing drugs from water at treatment plants. They also said unused drugs should be brought to take-back programs where they exist, instead of being flushed down the toilet. And they called on pharmaceutical companies to work on "greener" drugs that degrade more easily.

Sandoz, one of three companies approved to sell oxazepam in the U.S., "shares society's desire to protect the environment and takes steps to minimize the environmental impact of its products over their life cycle," spokeswoman Julie Masow said in an emailed statement. She provided no details.

Wall Street ends slightly higher, helped by acquisitions

NEW YORK (Reuters) - The S&P 500 eked out a small gain for a third straight session on Thursday, helped by a flurry of merger activity, though investors see no catalysts to lift the market further with major averages near multi-year highs.

The market's slowed advance took the S&P 500 to its highest intraday level since November 2007 on Wednesday. While the index notched its third straight day of gains, none was more than 0.2 percent.

Shares of H.J. Heinz Co jumped 20 percent to $72.50 after it said Warren Buffett's Berkshire Hathaway and 3G Capital will buy the food company for $72.50 a share, or $28 billion including debt. Berkshire's class B shares rose 1.3 percent to $99.21.

Also supporting the market was data showing the number of Americans filing new claims for unemployment benefits fell more than expected in the latest week. The CBOE Volatility index <.vix> fell 2.4 percent, dropping to 12.67.

"While I'm not bearish, I don't see many upside motivations at these levels," said Donald Selkin, chief market strategist at National Securities in New York, who cited the low level of the VIX as a sign the market was overbought.

Equities have struggled to break above current levels where they have been hovering for almost two weeks. The S&P 500 is up more than 6 percent so far this year.

"We need to digest some of our gains to go higher, but people are so eager to buy on the dips that we're not even seeing dips anymore. People are just chasing the market higher," said Selkin, who helps oversee about $3 billion in assets.

Stocks fell earlier after a report the euro zone's gross domestic product contracted by the steepest amount since the first quarter of 2009. In addition, Japan's GDP shrank 0.1 percent in the fourth quarter, crushing expectations of a modest return to growth.

The Dow Jones industrial average <.dji> was down 9.52 points, or 0.07 percent, at 13,973.39. The Standard & Poor's 500 Index <.spx> was up 1.05 points, or 0.07 percent, at 1,521.38. The Nasdaq Composite Index <.ixic> was up 1.78 points, or 0.06 percent, at 3,198.66.

Constellation Brands soared 37 percent to $43.75 after AB InBev's deal to take over Mexican brewer Grupo Modelo was revised to grant Constellation perpetual rights to distribute Corona and other Modelo brands in the United States. U.S. shares of AB InBev gained 5.1 percent to $92.77.

American Airlines and US Airways Group said they plan to merge in a deal that will form the world's biggest air carrier, with an equity valuation of about $11 billion. US Airways shares fell 4.6 percent to $13.99.

Weakness in Europe contributed to a 5 percent drop in revenue from the region for Cisco Systems , which nonetheless beat estimates as it reported its results late Wednesday. The company's shares dipped 0.7 percent to $20.99.

General Motors Co reported a weaker-than-expected fourth-quarter profit, also citing bigger losses in Europe alongside lower prices in its core North American market. The stock was off 3.3 percent to $27.73.

Only five more stocks rose than fell on the New York Stock Exchange, while 51 percent of Nasdaq-listed shares closed higher.

Volume was light, with about 6.36 billion shares changing hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, below the daily average so far this year of about 6.48 billion shares.

Lady Gaga Cancels Born This Way Ball Tour Due to Severe Injury

02/13/2013 at 08:50 PM EST

It's a somber week for Lady Gaga – and her Little Monsters.

Following Tuesday's Facebook announcement that she was "devastated and sad" because she couldn't walk and had to postpone several Born This Way Ball concerts, the pop star, 26, has officially canceled the remaining dates of her world tour.

"After additional tests this morning to review the severity of the issue, it has been determined that Lady Gaga has a labral tear of the right hip," the singer's rep told PEOPLE Wednesday in a statement. "She will need surgery to repair the problem, followed by strict down time to recover. This unfortunately, will force her to cancel the tour, so she can heal."

Refunds for the cancelled performances will be available at point of purchase starting on Thursday.

"I hope you can forgive me, as it is nearly impossible for me to forgive myself," she wrote the previous day of postponing the dates. "I hate this. I hate this so much. I love you and I'm sorry."

Get well, Gaga!

Clues to why most survived China melamine scandal

WASHINGTON (AP) — Scientists wondering why some children and not others survived one of China's worst food safety scandals have uncovered a suspect: germs that live in the gut.

In 2008, at least six babies died and 300,000 became sick after being fed infant formula that had been deliberately and illegally tainted with the industrial chemical melamine. There were some lingering puzzles: How did it cause kidney failure, and why wasn't everyone equally at risk?

A team of researchers from the U.S. and China re-examined those questions in a series of studies in rats. In findings released Wednesday, they reported that certain intestinal bacteria play a crucial role in how the body handles melamine.

The intestines of all mammals teem with different species of bacteria that perform different jobs. To see if one of those activities involves processing melamine, researchers from the University of North Carolina at Greensboro and Shanghai Jiao Tong University gave lab rats antibiotics to kill off some of the germs — and then fed them melamine.

The antibiotic-treated rats excreted twice as much of the melamine as rats that didn't get antibiotics, and they experienced fewer kidney stones and other damage.

A closer look identified why: A particular intestinal germ — named Klebsiella terrigena — was metabolizing melamine to create a more toxic byproduct, the team reported in the journal Science Translational Medicine.

Previous studies have estimated that fewer than 1 percent of healthy people harbor that bacteria species. A similar fraction of melamine-exposed children in China got sick, the researchers wrote. But proving that link would require studying stool samples preserved from affected children, they cautioned.

Still, the research is pretty strong, said microbiologist Jack Gilbert of the University of Chicago and Argonne National Laboratory, who wasn't involved in the new study.

More importantly, "this paper adds to a growing body of evidence which suggests that microbes in the body play a significant role in our response to toxicity and in our health in general," Gilbert said.

Wall Street pauses after rally to five-year high

NEW YORK (Reuters) - Stocks drifted in light volume on Wednesday, ending little changed, as investors remained cautious after the S&P 500 index briefly hit its highest intraday level since November 2007.

The S&P 500 was buoyed by General Electric after cable company Comcast Corp said it will buy from GE the the part of NBCUniversal it didn't already own for $16.7 billion.

Comcast's stock hit the highest since 1999 before closing up 3 percent at $40.13 and GE gained 3.6 percent to $23.39.

The S&P 500 is up 6.6 percent so far this year, partly due to stronger-than-expected corporate earnings and a better economic outlook. The Dow industrials is about 1 percent away from an all-time intraday high, reached in October 2007.

Volume has been weak in recent days with the S&P moving sideways around 1,520. The index is about 3 percent away from closing at a record high.

A scarcity of sellers after a consistent string of gains is a positive sign and shows the uptrend is intact, King Lip, chief investment officer at Baker Avenue Asset Management in San Francisco, said.

"Last year we had double-digit returns in the first quarter. It's fairly possible we can move higher from here," he said.
