5 Momentum Stocks to Buy for January After a Mixed December

Read MoreHide Full Article

Key Takeaways

  • U.S. stock momentum to continue in January despite a mixed December, supported by earnings and Fed policy.
  • HOOD is accelerating growth via AI tools, new banking features, crypto expansion and global market reach.
  • CIEN is seeing strong AI-driven demand, lifting revenue outlook on cloud and service momentum.

Wall Street’s rally of U.S. stocks in 2023 and 2024 continued in 2025, albeit at a slow pace. In 2025, the three major stock indexes — the Dow, the S&P 500 and the Nasdaq Composite — were up 13%, 16.4% and 20.4%, respectively.

However, the last month of last year was mixed. The Dow and the S&P 500 were up 0.7% and 0.3%, respectively. On the other hand, the tech-heavy Nasdaq Composite fell 0.5%. Concerns about the continuation of artificial intelligence (AI) trade resulted in profit booking on AI-centric technology behemoths.

Nevertheless, U.S. stock market momentum is likely to continue in January supported by the strong fundamentals of the domestic economy, solid fourth-quarter 2025 earnings projections, the Fed’s accommodative monetary policies and the evaporation of trade and tariff-related issues. 

At this stage, it will be prudent to invest in stocks with a favorable Zacks Rank that have momentum in January. Five such stocks are: Robinhood Markets Inc. (HOOD - Free Report) , MongoDB Inc. (MDB - Free Report) , Samsara Inc. (IOT - Free Report) , Ciena Corp. (CIEN - Free Report) and Core & Main Inc. (CNM - Free Report) . Each of our picks currently sports a Zacks Rank #1 (Strong Buy) and has a Zacks Momentum Score of A or B. You can see the complete list of today’s Zacks #1 Rank stocks here.

Driven by strong cloud and service provider momentum, CIEN gained 2 points of optical market share year to date and expects further gains in 2026. 

Networking Platforms revenue rose 22% to $1.05 billion, driven by 19% Optical growth on a 72% RLS surge and 49% growth in Routing and Switching from DCOM demand. CIEN lifted its fiscal 2026 revenue outlook to $5.7-$6.1 billion, nearly 24% growth at the midpoint, up from the prior 17%, on strong demand from cloud, DCI, and AI infrastructure.
