The Nasdaq Composite closed lower on Thursday for a fifth consecutive session — its longest losing streak since October 2022.

The tech-heavy Nasdaq Composite dipped 0.56% to end at 14,510.30. Since the Dec. 27 close, the index has lost nearly 4%. The S&P 500 slid 0.34%, marking a fourth day of declines, finishing at 4,688.68. The Dow Jones Industrial Average was the outlier, eking out a 10.15-point gain, or 0.03%, to close at 37,440.34.

Mega-cap tech stocks such as Apple are underperforming to start the year, as overstretched valuations and uncertainty around when the Federal Reserve will begin to cut rates have investors worried that markets have gotten overly optimistic.

Apple stock is down more than 5% this week. Shares of the tech giant fell more than 1% on Thursday following a downgrade by Piper Sandler, two days after Barclays also lowered its rating on the name.

The recent performance on Wall Street comes in stark contrast to how the market ended 2023. The S&P 500 ended last year up more than 24% while enjoying its best weekly win streak going back to 2004.

But Steven Wieting, chief investment strategist of Citi Global Wealth, doesn't believe that the recent pullback will have many long-term repercussions on the market.

"Whether any of this lasts, I wouldn't really look to the last few days as mattering very much," he told CNBC. "It's really a statistical coin toss."

In fact, Wieting thinks the S&P 500 could end the year around the 5,000 level, which would indicate more than 6% upside from here.

Nasdaq closes lower for fifth straight day

The Nasdaq Composite closed lower for the fifth trading day in a row.

The tech-heavy index slid 0.56% to settle at 14,510.30, while the S&P 500 finished 0.34% lower to close at 4,688.68. The Dow Jones Industrial Average, on the other hand, gained 10.15 points, or 0.03%, to end at 37,440.34.

Sunrun CEO says rate cuts, IRA tax benefits are major tailwinds in 2024

Sunrun sees major tailwinds in 2024 from expected interest rates cuts, falling hardware costs and tax benefits from the Inflation Reduction Act, CEO Mary Powell told CNBC Thursday.

The solar company's stock has fallen more than 28% over the past 12 months as elevated rates have made installations more expensive for households, dampening demand.

Powell said Sunrun had factored in a higher cost of capital into its outlook for 2024, so lower rates would act as a catalyst. The solar installer's stock is up more than 60% over the past three months as the Federal Reserve has kept rates steady. The central bank has indicated three cuts this year.

"We're actually doing much better already in the last few months with what has happened with rates and the outlook for '24," Powell told CNBC's Brian Sullivan at Goldman Sach's energy conference in Miami.

IRA tax credits for middle and lower income households will start flowing in the economy this year which will act as a tailwind, Powell said.

Sunrun is focused on generating cash in 2024 with a forecast of $200 million to $500 million by the end of the year, she said.

Bernstein says Lilly's direct-to-consumer site will be a 'niche market'

Eli Lilly stock is off its high for the day heading into the close. Earlier, the stock climbed to $636.41, a 52-week high, after the drugmaker announced plans to sell some of its drugs, including anti-obesity drug Zepbound, directly to consumers. The site, LillyDirect, will focus on chronic conditions such as migraine, diabetes and weight loss, with the company saying that these patients face hurdles to treatment. The goal will be to connect patients to doctors and ship medicines to patient homes via third-party pharmacies.

But Bernstein analyst Lance Wilkes, who covers health insurance companies, said the effort isn't a threat to pharmacy benefit managers.

"We see drug company specific dispensing as a niche market, given that this will likely cater to cash pay customers, would not be a single pharmacy contact for a consumer given its lack of other drug company products, and would not likely be able to identify drug interactions (a function PBMs perform and provide to pharmacies)," Wilkes wrote in a research note.

Wilkes is anticipating "slow, but expanding coverage" of drugs like Zepbound, driven by the desire to improve patient health and lower costs over time as the motivation to pay for medications that can cost $10,000 or more annually.

Oil prices fall as U.S. fuel inventory build up overshadows Mideast tensions

Oil prices fell on Thursday as a huge U.S. fuel inventory buildup overshadowed worries about supply disruptions from mounting tensions in the Middle East.

The West Texas Intermediate contract for February lost 51 cents, or .7%, to settle at $72.19 a barrel. The Brent contract for March shed 66 cents, or .84%, to settle at $77.59 a barrel.

U.S. gasoline stocks increased by 10.9 million barrels to 237 million barrels total for the week ending Dec. 29, according to data from the Energy Information Agency. Motor fuel supplied to the market, an indicator of demand, fell by 1.2 million barrels per day to nearly 8 million barrels per day total.

The U.S. inventory build shifted focus away from mounting tensions in the Middle East. Crude prices rose more than 2% on Wednesday as militant attacks disrupt shipping in the Red Sea and a Libyan oilfield was shutdown due to protests.

Solar stocks slumping in 2024; Enphase, Sunrun downgraded Thursday at KeyBanc

Solar stocks are slumping to start 2024, continuing last year's miserable performance. The latest catalyst was a downgrade of Enphase Energy and Sunrun at KeyBanc Capital on Wednesday.

Enphase fell to sector weight at KeyBanc, where analysts led by Sophia Karp said "the timing of recovery in demand is uncertain due to a poorly quantifiable inventory glut in the channel." The oversupply has lasted longer than originally anticipated, and an improvement isn't immediately visible, they said.

Sunrun also dropped to sector weight at KeyBanc after a recent rally fueled by falling Treasury yields drove its stock close to the broker's price target. That left Sunnova Energy as KeyBanc's only stock in the industry rated overweight, "as it presents a greater margin of safety," the bank said.

So far in 2024, Sunrun has slumped 12% (down 18% in 2023), SolarEdge Technologies is off 11% (-67% in 2023), Enphase is lower by 10% (-50% in 2023) and Sunnova has lost more than 9% (-15% in 2023). The Invesco Solar ETF has fallen more than 6% in 2024 after slumping 26% last year.

Spending on holiday items rose 0.3% year-over-year in December, according to Bank of America

Bank of America credit and debit card data showed that total card spending per household rose 1% in the week ending Dec. 30 as compared to one year ago.

Analyst Shruti Mishra added that while shopping on holiday items fell 1.3% in the week ending Dec. 30, spending on holiday items rose 0.3% in the five weeks from Thanksgiving to Dec. 30 as compared to the same time period in 2022.

Investors will still want to hold mega-cap growth stocks, says Citi's Scott Chronert

Citi equity strategist Scott Chronert remains bullish on technology stocks, despite their pullback so far in 2024.

"We continue on the view that you want to be a holder of growth in the mega-cap growth cohort of the market," he said on CNBC's "Squawk on the Street" on Thursday morning. "With the [communications services] downgrade we're lightening on the internet component of that but remain quite constructive on tech, particularly on software."

Sector-wise, Chronert is also overweight industrials and financials.

Financials are a good sector to focus more on cyclical behavior over growth, he said. In particular, bank stocks have strong fundamentals and currently look relatively attractive in a "pretty aggressively valued" market, Chronert added.

Wells Fargo's Christopher Harvey points to investor repositioning as reason for market pullback

After a tremendous year-end rally in 2023, equities have struggled out the gate to start 2024.

Wells Fargo analyst Christopher Harvey pointed to investor reshuffling as the reason behind the latest market pullback.

"The market is two for two this year and many are trying to divine the meaning," he wrote in a Thursday note. "The evidence points to a hangover from year end hedge fund repositioning supporting our 2024 risk aversion bias."

Bank of America kicking 2024 off with an 'all-time low valuation for China consumer'

Deflation, a weak macroeconomic backdrop, lagging stimulus and low consumer and business confidence have all contributed to Bank of America's bearish outlook for the Chinese consumer.

In this environment, analyst Chen Luo wrote that companies that deliver higher functional and emotional value may be more resilient, as will sectors with more favorable supply-side dynamics.

"The shift from growth to value is ongoing, with more attention paid to FCF/dividend yield," he added. "Staples, should they continue to underperform, could become interesting in 2H24, due to likely rising yield, even cheaper valuation after rollover to 2025 and easier comps."

Luo highlighted New Oriental Education & Technology Group and TAL Education Group as his two preferred names, upgrading the latter to a buy rating from neutral.

Mobileye sheds 25% on revenue warning, Bank of America downgrades to underperform

Mobileye's stock sank 25% after the Intel-backed self-driving technology company warned of a pullback in customer orders in the first quarter of 2024, expecting revenue to fall 50% year over year for the period.

"We have become aware of excess inventory at our customers," Mobileye said in a preliminary full-year outlook.

Much of the excess inventory stems from Tier 1 customers stocking up on chips as supply chains struggled in 2021 and 2022 to circumvent shortages and lower production at original equipment manufacturer in 2023, the company said.

The news pressured other automotive chipmaking stocks NXP Semiconductors and On Semiconductor lost 3.2% and 2%, respectively. Analog Devices lost more than 1.5% and Intel shares were marginally lower.

Bank of America also downgraded the Israel-based company to an underperform rating, citing the inventory build up and disappointing outlook.

"We have been somewhat wary of the growth and implied valuation of the stock, but now growth (and profits) are even more uncertain," wrote analyst John Murphy.

Walgreens stock plummets 7% after dividend cut

Shares of Walgreens Boot Alliance plunged more than 11% on Thursday after the company slashed its quarter dividend by nearly half.

The decision to cut its dividend to 25 cents per share from 48 cents was taken to "strengthen [its] long-term balance sheet and cash position," CEO Tim Wentworth said in a statement. The stock was last down 6.5%.

The dividend reduction overshadowed strong quarterly results. The company earned an adjusted 66 cents per share on revenue of $36.71 billion, higher than the 61 cents per share on revenue of $34.86 billion expected by analysts polled by LSEG.

Online spending rose 4.9% to $222.1 billion this year, Adobe says

Adobe Analytics is out with more evidence of a strong holiday season. The firm said spending online rose 4.9% to a record $222.1 billion between Nov. 1 and Dec. 31.

What's more, the higher sales reflect stronger demand, not the impact of inflated prices. According to the Adobe Digital Price Index, e-commerce prices declined 5.3% across 18 product categories in December compared with the year-earlier period.

Adobe said retailers drew consumers in by tempting them with discounts — and not just on Cyber Monday and Black Friday. Daily spending online topped $4 billion on 11 days, which was a new high for that measure.

Shoppers were increasingly making purchases on their phones, with mobile orders topping desktop for the first time. Curbside pickup remained an in popular option, with roughly 1 in 5 orders using the service, especially in the days leading up to Christmas.

Investor optimism above average for 9th week in latest AAII poll

Individual investor optimism about the forward outlook for stocks remained above the historical average for a ninth consecutive week in the latest poll by the American Association of Individual Investors.

Bullishness toward stocks over the next six months rose to 48.6% in the latest week, up from 46.3% and the long-run historical average of 37.5%. Bearishness fell to 23.5% from 25.1%, the ninth straight week it's run below the historical average of 31%.

Neutral opinion on stocks fell to 27.9% in the latest poll from 28.6%, below an historical average of 31.5% for the 13th time in 14 weeks, AAII said.

Persistent bullishness and diminished bearishness are red flags for contrarian investors who try and go against the crowd. They figure that when more people say they're optimistic, most of the buying is already over and there's less cash on the sidelines to go into stocks.

Oppenheimer's Stoltzfus expects S&P 500 to rally 10% in 2024, positive earnings season

The new year may have kicked off with an equities pullback, but Oppenheimer chief market strategist and market bull John Stoltzfus believes that the S&P 500 could rally more than 10% in 2024.

Stoltzfus told CNBC's "Squawk Box" on Thursday morning that the S&P 500 could end the year at 5,200, which is 10.5% above the index's Wednesday closing level of 4,704.81. For this to happen, he anticipates that both valuations and price-to-earnings multiples will move higher.

For the upcoming earnings season, Stoltzfus expects investors to be surprised to the upside.

"We think analysts have been remarkably conservative in anticipating how companies are going to perform," he said. "Companies have used technology to weather that and navigate what would normally be a pretty tough environment when the Fed is at a Fed Funds hike cycle."

Stoltzfus added that he's also optimistic on the U.S.'s economic outlook this year.

"When you consider 11 hikes and four pauses insofar and no recession [along with] the resilience that's seen in business and the consumer as well as in labor, all this looks remarkably good," he said. "We might actually skirt a recession and now we're even beginning to think perhaps we do get a soft landing, which would be remarkable."

Services sector growth picks up slightly in December, S&P says

The S&P Global services sector PMI came in at 51.4 in December, slightly above a November print of 50.8. Economists polled by Dow Jones expected the number to come in at 51.3.

"Some New Year cheer is provided by the PMI signalling an acceleration of growth in the vast services economy, which reported its largest rise in output for five months in December," S&P Global Market Intelligence chief business economist Chris Williamson said.

"The improvement overshadows a downturn recorded in manufacturing to indicate that the overall pace of US economic growth likely accelerated slightly at the end of the year," he added.

Jobless claims total 202,000, well below estimate

The pace of layoffs decelerated in the final full week of 2023, a sign that the labor market is still tight, the Labor Department reported Thursday.

ADP report shows stronger than expected job growth in December

Private payroll growth topped estimates for growth in December, according to an ADP report Thursday showing a still-vibrant labor market.

Caixin China December services PMI expands at fastest rate since July

A private survey showed services activity continued to grow in China in December, with foreign demand for the country's services also rising.

The Caixin China General Services Business Activity Index rose to 52.9 in December compared with 51.5 in November, climbing for a 12th straight month. The survey also noted that the rate of growth was the fastest since July.

"Growth momentum across China's service sector continued to revive at the end of 2023," according to the survey report. "Employment registered a subtle uptick as businesses exercised caution in hiring. But the slight expansion was sufficient to absorb new orders, keeping backlogs of work unchanged."

A PMI reading above 50 indicates expansion in activity, while a reading below that level points to a contraction.

Australia stocks extend slide, hit two-week lows

Australia stocks continued to slide after hitting a record high earlier this week, falling to two-week lows on Thursday.

The S&P/ASX 200 fell 0.53% to trade near 7,495 — its lowest level since Dec. 19 — retreating from an all-time high of 7,632.70 hit on Tuesday.

Aussie markets fell, tracking a somber global mood after minutes of the U.S. Federal Reserve's meeting in December showed interest rate cuts were likely in 2024, but provided little clarity on when that might happen.

Bets that the Reserve Bank of Australia will no longer be raising rates have buoyed the country's stock market — but those hopes have been partly driven by the Fed's dovish shift.

The Aussie dollar strengthened 0.1% against the U.S. dollar in early trading.
