Longest streak in history! The semiconductor index achieves a 16-day winning streak: Amid the full-scale explosion of AI infrastructure, who is the biggest winner?

Since the end of March, the US stock market has been witnessing a historic surge: the Philadelphia Semiconductor Index achieved an impressive '16 consecutive gains,' skyrocketing 39% in a single rally, marking the longest winning streak in nearly 30 years. If this trend continues, April is highly likely to become the best-performing month for this sector since the peak of the dot-com bubble in 2000.

Attributing this rally solely to 'market enthusiasm for AI' seems overly simplistic. When we look beyond the surface of the index's explosive rise and examine the top ten gainers year-to-date, a clear undercurrent of capital is emerging:The investment logic of smart money has evolved from the early 'GPU-only theory' and 'NVIDIA's solo performance' to a systematic reassessment of AI infrastructure.

A deeper analysis of the top 10 gainers on the PHLX Semiconductor Index reveals that this surge is not a one-player show but rather a systematic explosion encompassing all core aspects of AI infrastructure:

Testing and materials 'enablers' take the lead: $Teradyne (TER.US)$ With an astounding year-to-date increase of 99.08%, it tops the list, while $Entegris (ENTG.US)$ 's strong performance highlights extreme market optimism towards upstream semiconductor testing equipment and specialty materials during the ramp-up phase of AI chips.

Data transmission and network interconnection explode: $Coherent (COHR.US)$ and $Marvell Technology (MRVL.US)$ Following closely behind. The exponential growth in data throughput and transmission speed requirements for large AI models has driven valuation increases in optical communications and customized networking chip sectors.

Reevaluation of Core Computing Power and Manufacturing Architecture: $Arm Holdings (ARM.US)$ 、 $Intel (INTC.US)$and$GlobalFoundries (GFS.US)$ This reflects the market's recognition of the core position of underlying computing architecture, instruction sets, and wafer fabrication in the AI era.

The Essential Need for Storage and Power Management: $Micron Technology (MU.US)$ The rise demonstrates the undersupply of storage components such as high-bandwidth memory; while $Monolithic Power Systems (MPWR.US)$ and $ON Semiconductor (ON.US)$ the inclusion reveals the enormous demand for high-performance power management and power semiconductors behind AI-intensive computing.

Investment Insight: How to Capture the 'Profit Effect' at All-Time Highs?

Facing an epic 16-day rally, investors must overcome fear of heights while avoiding blind chasing.

Shift Perspectives, Embrace the 'Entire Supply Chain': Stop searching for 'the next NVIDIA'; expand asset allocation to testing materials, optical communications, advanced storage, and power management sectors. By constructing thematic baskets or related ETFs, one can more steadily capture systematic benefits from AI hardware upgrades.

Beware of profit-taking, Return to 'Earnings Validation': The unprecedented consecutive gains have inevitably accumulated substantial profit-taking pressure. As the earnings season progresses, the market will shift from 'valuation expansion' to 'earnings verification.' Any rumors about delays in HBM capacity delivery or order cuts for optical modules could trigger significant volatility.

Positioning core assets on dips: Core players within the supply chain that possess strong pricing power and whose order visibility extends into next year remain the preferred safe haven when funds pull back. Leveraging short-term market fluctuations to accumulate positions at key support levels in batches is currently the most cost-effective strategy.

In summary,As industry insiders have pointed out, driven by the strong push of artificial intelligence, the current demand in the semiconductor market is very robust. More importantly, across all sectors, large-scale infrastructure investments in AI are expected to continue into the foreseeable future.

From both a valuation and growth potential perspective, the industry still holds immense appeal. This momentum ignited by AI infrastructure not only brings a historic opportunity for semiconductor stocks as a whole, but its spillover effects are also becoming a core engine driving the sustained upward trajectory of the entire U.S. stock market.
