Stocks declined on Friday, led by technology names, with the Dow Jones Industrial Average erasing earlier gains in the holiday-shortened week.

The blue-chip Dow shed more than 500 points, falling for the first time in six sessions. The S&P 500 fell 1.6% with all 11 sectors in the red. The Nasdaq Composite slid 2.2% as Tesla dropped 5%, and Nvidia declined more than 3%. Amazon, Microsoft and Alphabet each fell at least 2%.

With Friday's sell-off, the Dow turned negative on the week, while the tech-heavy Nasdaq sat near flat. The S&P 500 is up just 0.2% this week after posting its best Christmas Eve performance since 1974 on Tuesday, according to Bespoke.

A rise in Treasury yields this week could be putting pressure on equities. The yield on the benchmark 10-year Treasury rose another 2 basis points Friday to 4.603% after the rate hit its highest level since May in the previous session.

"I think what you're seeing today is a lack of faith," Alan Rechtschaffen, UBS Global Wealth senior portfolio, said on CNBC's "Market Movers." "I think there's a lot of noise about tariffs, there's a lot of concern about productivity."

Still, some investors remain hopeful that stocks will rise into the new year, spurred by the so-called "Santa Claus rally." This refers to the market's tendency to rise in the final five trading days of the year and the first two in January. Since 1950, the S&P 500 has returned 1.3% on average during this period, outpacing the market's average seven-day return of 0.3%, according to LPL Financial. 

"The nation is experiencing a collective sigh of relief after navigating through a contentious election cycle and unusual market dynamics to end 2024 with strong year-to-date gains," said Todd Ahlsten, chief investment officer at Parnassus Investments. "Looking ahead to 2025, the markets are expected to broaden and improve."

In December, the Nasdaq is on pace for a 2% advance, lifted by a jump in Tesla and Alphabet shares, as well as by a rally in Apple that's brought the iPhone maker closer to a $4 trillion market cap. The S&P 500 is down 1.5% on the month. The Dow is on pace for its worst month since April, with a roughly 4.7% decline.

Megacap tech among Friday's worst performers

Megacap technology stocks were among the worst performers during Friday's session.

Nvidia slumped about 3%, while Amazon, Broadcom, Microsoft, Apple, Alphabet and Meta Platforms dropped at least 2% each. Tesla shed about 5%.

The group is on pace for a mixed week-to-date performance, with Nvidia, Tesla and Meta Platforms on track for gains, with Broadcom up more than 8%. Microsoft has slumped more than 2%, while Amazon is down 1.5%.

Broadcom shares have surged nearly 48% this month and are poised to notch their best month on record.

AT&T among the names added to Citi's focus list heading into 2025

AT&T may be poised for outperformance over the next year, according to Citi.

The stock was recently added to the firm's focus list that contains its bottom-up, highest conviction ideas for North America. Shares have already outperformed the broader market this year, rising more than 36% year to date.

For AT&T, analyst Michael Rollins believes the market is underappreciating the company's opportunity to sustain strong annual performance in its mobility segment as well as expand financial contributions within its consumer wireline segment.

"AT&T has a multi-year opportunity to deepen its focus on converged mobile + broadband services and improve financial performance," he wrote in a recent note to clients.

Medical device maker Boston Scientific was another name added to the list. That stock has also outperformed the broader market, notching year-to-date gains of nearly 57%.

South Korea-tied stocks retreat

U.S.-listed shares of South Korean stocks pulled back on Friday after lawmakers pushed out their second head-of-state since martial law was briefly put into place earlier this month.

The iShares MSCI South Korea ETF (EWY) slid more than 1%, notching a new 52-week low. Notably, U.S.-listed shares of Korea Electric Power slid more than 2%, while Posco Holdings shed more than 1.5%. Coupang and KT Corp were also among the decliners.

Those drops came after acting President Han Duck-soo was impeached. It comes just weeks after former President Yoon Suk Yeol faced the same fate following his decision to place the country under martial law for the first time in more than four decades.

S&P 500 likely to rally another 16% in 2025, Capital Economics markets economist says

The S&P 500 is likely to end next year near 7,000, or nearly 16% above where the index closed Thursday, according to a forecast reiterated by Capital Economics chief markets economist John Higgins between last week's Fed meeting and Christmas.

The London-based researcher is sticking with the projection even though "we think Fed policy will be a bit less accommodative than we had previously projected," and a sell-off in bonds drove last week's weakness in stocks.

The sanguine view is based on a belief that "the 10-year TIPS yield — which is typically used as a proxy for this risk-free component because equities are 'real' assets — won't end next year higher than it is now," Higgins wrote. 

"What's more, we still aren't expecting a major deficit-financed fiscal expansion in the U.S. that could bring out the bond vigilantes and drive up Treasury term premia substantially from still-low levels by the standards of the past," Capital Economics said. In addition, forward 12-months earnings per share for the S&P 500 "will continue to grow a bit next year."
