Wall Street finished the trading week on a weaker note as investors digested a fresh batch of economic data and corporate earnings results.
For the week, the S&P (SP500) lost -1.4%, while the tech-heavy Nasdaq Composite (COMP:IND) dipped -2.1%, and the blue-chip Dow (DJI) fell -1.2%. The Dow crossed 50,000 points for the first time in its history this week, marking a major milestone for the long-running U.S. stock market index.
On the economic front, data showed mixed signals in January, as the CPI rose 0.2% month over month—below the +0.3% consensus estimate and easing from December’s 0.3% increase—according to the Bureau of Labor Statistics. At the same time, nonfarm payrolls increased by 130,000, significantly exceeding the +70,000 consensus forecast and well above December’s revised gain of 48,000 (previously reported as +50,000).
On the earnings front, results continued to drive sharp stock-specific moves.
Here’s what caught investor attention this week:
Kraft Heinz (KHC) announced alongside its quarterly earnings that it is pausing its previously planned separation into two standalone companies. Instead, management will focus on strengthening the existing business through increased investment.
Hims & Hers (HIMS) fell sharply after the company reversed course and abandoned its planned launch of a low-cost, compounded version of Novo Nordisk’s (NVO) Wegovy weight-loss drug amid regulatory pressure and legal threats.
Google parent Alphabet (GOOG) (GOOGL) has tapped the debt markets by issuing a large amount of bonds to help fund its massive artificial intelligence build-out, including an unusually long-dated 100-year bond as part of a global bond sale. The Sundar Pichai-led tech giant stunned Wall Street earlier this month when it said it would spend between $175B and $185B on capital spending in 2026, as it looks to ramp up artificial intelligence momentum across the entire company.
Moderna (MRNA) shares fell after the FDA issued a refusal-to-file letter for its investigational influenza vaccine, mRNA-1010, saying the application lacked an adequate, well-controlled trial due to an inappropriate control arm, though the agency flagged no safety or efficacy issues. Moderna called the decision inconsistent with prior FDA communications, requested a meeting to discuss next steps, and said it does not expect any impact on its 2026 guidance.
Roku (ROKU) shares jumped on Friday after the streaming platform beat Wall Street expectations with its fourth-quarter results and issued an upbeat 2026 growth outlook. The company reported a net profit of $80.5M, or $0.53 per share, in Q4, reversing a net loss of $35.5M a year earlier. Revenue rose 15.8% year over year to $1.39B. Growth was fueled by record fourth-quarter premium subscription net adds, driven in part by holiday promotions.
Pinterest (PINS) fell on Friday after the company warned about revenue headwinds in the short term driven by large retailer ad pullbacks due to tariffs. The company said tariffs will further reduce ad spending in Europe and North America, and its impact will be “slightly more pronounced” in the current quarter. For Q1, revenue was guided in the $951M to $971M range, or 11%-14% growth, coming below the consensus estimate of $980.6M.
Fastly (FSLY) shares more than doubled this week after the company beat fourth-quarter expectations. The content delivery network reported adjusted EPS of $0.12 on revenue of $172.6M (+22.8% Y/Y), topping estimates of $0.06 and $161.4M. Remaining performance obligations rose 55% Y/Y to $353.8M, marking a record level.
Astera Labs (ALAB) shares fell nearly 24% over the week even as the tech company reported fourth-quarter results that topped Wall Street’s forecast. For the period ending Dec. 31, Astera said it earned an adjusted $0.58 per share as revenue soared 91.8% year-over-year to come in at $270.6M.
Cisco Systems (CSCO) fell ~10% over the week even as the networking giant posted second-quarter results and guidance that topped Wall Street’s forecast. However, rising memory costs and margin had some investors expressing concern. For the period ending Jan. 24, Cisco said it earned an adjusted $1.02 per share as revenue rose 10% year-over-year to $15.35B. Looking to the third-quarter, Cisco said it expects sales to be between $15.4B and $15.6B, above the $15.2B analysts were expecting.
Nebius (NBIS) fell after the AI infrastructure provider reported Q4 revenue growth of 547% Y/Y to $227.7M but missed consensus estimates, while costs surged. Operating expenses jumped 169% Y/Y to $462.2M, driving an adjusted net loss of $173M vs. a $69M loss a year earlier, overshadowing the headline growth.
