AI Chip Supply Chain Stocks Surge in 2024: Are Investors Chasing Overheated Profits?

The AI Gold rush has spilled over into semiconductor supply chain stocks, with equipment makers like Teradyne, Lam Research, and KLA Corp. posting staggering gains of 40-90% this year. But as valuations approach nosebleed levels, analysts warn this momentum may be built on shaky foundations. Here's why the smart money is watching order books rather than stock charts.
Why Are Chip Equipment Stocks Outperforming the Broader Market?
In what's becoming the year's most unexpected tech rally, semiconductor equipment stocks have left even AI darling Nvidia in the dust. Teradyne's shares have doubled since April, while Lam Research and KLA Corp. have delivered 68% returns - making them top performers in the Philadelphia Semiconductor Index. The secret sauce? Testing gear for memory chips used in AI systems has become the industry's hottest commodity.
As Microsoft and Alphabet pour billions into AI infrastructure, chipmakers are scrambling to expand capacity. But with established players like Nvidia trading at premium valuations, investors have turned to the picks-and-shovels suppliers. "It's classic late-cycle behavior," notes BTCC analyst Mark Chen. "When the gold miners get expensive, you buy the equipment vendors."
Memory Chip Demand Fuels the Fire
The real action is happening in memory hardware - typically tech's most boring sector. Micron Technology's 90% surge this year tells the story: high-bandwidth memory (HBM) has become the unsung hero of the AI revolution. Equipment suppliers feeding this boom are reaping the rewards:
| Company | 2024 Gain | P/E Ratio | Key Customers |
|---|---|---|---|
| Teradyne | 100%+ | 32x | Samsung, SK Hynix |
| Lam Research | 68% | 30x | Micron, TSMC |
| KLA Corp | 68% | 30x | Micron, Intel |
Susquehanna's Mehdi Hosseini recently raised Teradyne's price target to $200 (49% upside), betting on wafer testing demand from TSMC. But here's the rub - these stocks now trade at 30-32x earnings, surpassing even the Philadelphia index average.
Valuation Warnings Flash Red
The party shows signs of getting out of hand. Lam Research recently saw a 14-day winning streak (a company record) before KeyBanc downgraded it, noting earnings haven't kept pace with the stock surge. Morgan Stanley and CFRA similarly cooled on KLA Corp. "Valuations assume perpetual order growth," warns Vaughan Nelson's Adam Rich, who oversees $17 billion. "Any pause in capex spending could trigger violent mean reversion."
Historical context matters: these stocks traded at 20x earnings just months ago. Now they're testing 30x - still below Broadcom's 36x multiple, but well above historical norms. The BTCC research team notes that similar valuation expansions in 2018 preceded 40% corrections when memory chip prices softened.
FAQs: AI Chip Supply Chain Investment
Why are semiconductor equipment stocks rallying?
The AI boom has created massive demand for testing and manufacturing equipment, particularly for high-bandwidth memory chips used in AI systems. As chipmakers expand capacity, equipment suppliers are seeing record orders.
How risky are these stocks at current levels?
With P/E ratios between 30-32x, these stocks price in perfect execution. Any slowdown in AI investment or chip inventory correction could spark significant pullbacks, as seen in past semiconductor cycles.
Which company has the most upside potential?
Analysts are particularly bullish on Teradyne (49% upside to $200 target) due to its expansion into wafer testing and potential TSMC contract wins. However, this assumes memory chip demand remains robust through 2025.
