A Review of the 2025 U.S. Stock Market
The U.S. stock market concluded 2025 with notable gains, as the S&P 500 rose approximately 17%, the Dow Jones Industrial Average grew around 13%, and the Nasdaq Composite climbed over 20%. While macroeconomic factors set the stage, the primary engine of the market remained the expansion of artificial intelligence.
Semiconductor and Hardware Leaders
Nvidia (NVDA) continued its historic run by becoming the first public company to reach a $4 trillion market valuation. The company ended the year up roughly 36%, fueled by its dominant position in the AI chip market. Observers noted that while the stock price grew, the pace was more moderate compared to the explosive gains of 2024.
Micron Technology (MU) emerged as a standout performer in the semiconductor space, with its stock price more than doubling in 2025, up about 239%. The company benefited from a massive ramp-up in high-value data center products and strong pricing for DRAM memory chips.
AMD (AMD) also saw significant growth, finishing the year up about 78%. The stock experienced significant dips in the spring but rallied strongly in the fourth quarter of the calendar year 2025.
Lam Research (LRCX), a key provider of equipment used to manufacture chips, saw its stock rise by roughly 137%. The company's success is closely tied to its leadership in "etch and deposition" technology, which is critical for building the complex layers in modern semiconductors.
Software and Cloud Innovators
Palantir Technologies (PLTR) was one of the top performers of 2025, with its stock gaining about 129%. The company’s focus on helping businesses integrate AI into their daily operations through its Artificial Intelligence Platform (AIP) resonated deeply with the market.
Alphabet (GOOG) experienced a strong year as its share price grew by approximately 64%. The company's performance was driven by a recovery in digital advertising and the expansion of its Google Cloud margins. Investors were particularly encouraged by Alphabet’s leadership in proprietary AI chips and the generative AI race.
Global Commerce and Commodities
Alibaba (BABA) saw a resurgence in 2025, with its stock price rising about 73%. This recovery followed several difficult years.
Newmont (NEM) reflected the "everything rally" of 2025 by gaining roughly 167%.
