Best-Performing Stocks and Sectors of 2025 — What 2026 May Bring

A powerful bull market in 2025 reshaped market leadership and set the tone for 2026.

The S&P 500 is on track to finish 2025 up more than 17%, extending a multi-year bull market driven largely by artificial intelligence spending and abundant capital. Beneath the index gains, however, leadership shifted in ways that offer important market context for traders and investors heading into 2026.

Key Points

• AI-linked infrastructure stocks dominated 2025’s best performers
• Gold and precious-metal miners surged alongside technology
• Consumer, retail, and managed-care stocks lagged amid policy and economic uncertainty

Winners of 2025: Where the Market Concentrated Capital

Technology stocks once again led the market, but 2025’s strongest performers extended well beyond mega-cap software platforms. The AI trade broadened decisively toward companies supplying the physical backbone of artificial intelligence.

Key areas of strength included:

• Data storage: Sandisk, Western Digital, and Seagate ranked among the S&P 500’s best performers as hyperscalers committed more than $440 billion to AI infrastructure.
• Semiconductors and equipment: Micron Technology and Lam Research posted triple-digit gains as demand surged across the chip manufacturing stack.
• AI-linked software: Palantir extended a multi-year rally as AI adoption spread across enterprise and government use cases.
• Retail trading platforms: Robinhood surged as market participation and crypto activity rebounded.
• Gold and miners: Gold prices climbed roughly 70% in 2025, lifting miners such as Newmont, Barrick Gold, and Agnico Eagle.
• Special situations: Warner Bros. Discovery rallied sharply on takeover speculation, underscoring how corporate events also shaped market reaction to news.

Which Sectors Fell Behind — and Why

Not every part of the market participated in the rally. Economic uncertainty and policy pressure weighed heavily on several defensive and consumer-focused groups.

Notable laggards included:

• Consumer staples: Tariffs and inflation concerns pressured companies such as Clorox, Campbell’s, and Constellation Brands.
• Retail and apparel: Weak U.S. demand dragged down names like Lululemon and Deckers Outdoor.
• Managed care: Health-insurance stocks underperformed amid regulatory uncertainty and pricing pressure.

These trends highlight how market sentiment in 2025 favored clear growth narratives and large capital-spending cycles over defensive positioning.

What 2025’s Leadership Signals for 2026

The clearest takeaway from 2025 is how concentrated capital became. Investors consistently favored companies tied to multi-year investment themes, particularly those linked to AI infrastructure and data-center expansion.

Looking toward 2026, attention is already shifting from headline AI beneficiaries to the “pick-and-shovel” companies that enable large-scale deployment:

• Data storage: Western Digital, Seagate Technology, and Sandisk support the growing demand for high-capacity data management.
• Power and energy infrastructure: Constellation Energy, Vistra, and GE Vernova are tied to the reliable electricity needed for always-on computing.
• Construction, cooling, and connectivity: Quanta Services and MasTec support data-center buildouts, while Vertiv and Eaton provide cooling and power management systems. Connectivity suppliers such as Amphenol and Corning help move data efficiently within these facilities.

Together, these areas illustrate how the AI trade is broadening beyond chips and software toward the infrastructure required to sustain long-term growth.

Gold’s strength alongside technology also signals persistent demand for hedges during periods of policy and geopolitical uncertainty — a dynamic that remains part of the broader market context heading into 2026.

What It Means for Investors

The stock market news explained by 2025’s winners is less about individual names and more about how markets reward durable growth drivers. AI spending, infrastructure buildouts, and hard-asset exposure attracted steady inflows throughout the year.

At the same time, sharp underperformance in consumer and health-care stocks shows how quickly sentiment can shift when policy risk rises. This divergence reinforces why market reaction to events played an outsized role in shaping returns.

As 2026 approaches, volatility risk in trading remains tied to how long AI-related spending holds up — and whether capital continues to favor concentrated themes over broader participation.

Conclusion

2025 delivered strong gains, but it was not an evenly shared rally. AI infrastructure, data storage, and gold defined the year, while consumer-oriented sectors struggled. These same forces will shape how markets react in 2026, as investors reassess where growth, resilience, and risk truly lie.
