Driven by fervent market enthusiasm for artificial intelligence and persistently high hardware demand, Wall Street's semiconductor sector has experienced a historic surge, with chip stocks achieving their strongest start to a year since the internet bubble of the millennium.
According to compiled data, the Philadelphia Semiconductor Index, which tracks 30 leading U.S.-listed chip companies, has risen approximately 75% year-to-date, positioning it for its best annual return since 1999.
Over the past two months, the index's total market capitalization has increased by over $5 trillion, a sum equivalent to 1.5 times the total market value of the UK's FTSE 100 index. This growth is underpinned by continuously improving market expectations for the future profitability of chip firms.
Prices for core AI chips and production equipment needed for new global wafer fabs have skyrocketed, with major suppliers struggling to meet the surging procurement demands of Silicon Valley tech giants.
This year, Meta, Alphabet (Google's parent company), Amazon, and Microsoft have collectively planned investments totaling $725 billion to build data centers and hardware infrastructure required for the AI era.
Charles Lemonides, founder of the ValueWorks hedge fund, stated, "The procurement demands from major cloud service providers are now fully materialized. The semiconductor and memory sectors are currently highly profitable, and this favorable trend is expected to continue for several years."
Strategists at Bank of America reiterated this week their strong confidence in the continued strength of the AI infrastructure sector. In a client research note, they wrote that current supply constraints, coupled with underestimated demand from governments, enterprises, and industrial sectors globally, sustain the industry's growth momentum.
AI labs OpenAI and Anthropic remain in a loss-making state due to heavy investments in data centers, yet both institutions are expected to achieve valuations exceeding $1 trillion when they go public later this year.
JPMorgan Chase CEO Jamie Dimon remarked at a conference on Tuesday, "Market enthusiasm is high at the moment, speculative sentiment is strong, and the current market conditions are favorable."
However, he also noted that similar periods of market frenzy preceded the major downturns of 1972, 1986, 2000, and 2007. Dimon added, "This situation makes me uneasy."
Since OpenAI launched the ChatGPT chatbot in 2022, the U.S. stock rally has long been dominated by the "Magnificent Seven" tech giants: Alphabet, Amazon, Apple, Meta, Microsoft, NVIDIA, and Tesla. This year, in addition to these seven, several chip stocks have also become major drivers of the market's ascent.
NVIDIA remains the world's highest-valued publicly listed company, with a total market capitalization of $5.1 trillion.
However, year-to-date, NVIDIA's three main competitors—Intel, Advanced Micro Devices, and ARM Holdings—have seen their stock price gains significantly outperform NVIDIA's. The market widely anticipates a gradual diversification of the AI infrastructure market, shifting away from sole reliance on NVIDIA's graphics processing units (GPUs) towards a greater emphasis on central processing units (CPUs), which has propelled the share prices of these three companies.
Intel raised its CPU demand forecast in its April earnings report, leading its stock price to surpass the historical high set during the internet bubble. The company's fortunes turned around last year following a 10% stake acquisition by the U.S. government and subsequent multi-billion dollar investments from NVIDIA and SoftBank.
NVIDIA's primary rival, Advanced Micro Devices, has recently secured substantial chip supply orders from Meta Platforms and OpenAI, resulting in a year-to-date stock price increase of over 120%.
SoftBank's ARM Holdings has undertaken a significant strategic shift: moving beyond designing hardware architectures for other manufacturers to developing its own chips that directly compete with NVIDIA's products. Bolstered by this strategic pivot, its stock price has surged over 160%. This UK-based company, whose major clients include NVIDIA, expects this transformation to help quadruple its revenue over the next five years.
The global supply-demand gap driven by data centers has also significantly benefited the memory chip sector. This week, major high-bandwidth memory manufacturers Micron Technology and SK Hynix both entered the trillion-dollar market capitalization club.
UBS stated that even after Micron's stock price surged approximately 860% over the past year, it could potentially double again within the next 12 months.
Semiconductor equipment manufacturers Lam Research and KLA have also seen substantial stock price gains.
Nelson Yu, Head of Equities at AllianceBernstein, commented, "Current market demand remains exceptionally high, and price increases have not dampened procurement enthusiasm."
However, he also cautioned that if the economy enters a recession, the massive spending plans of large technology companies would likely be scaled back, as even industry giants have procurement budget limits.
He added, "It's not straightforward to label the current market conditions a bubble. AI has indeed created tangible market demand. But, as with all commodities, there is a risk that price increases could eventually suppress demand."
