Choi Il-ho — Vice President, Chesley Investment Advisory

Summary

Choi Il-ho, Vice President at Chesley Investment Advisory, argues that US investors should focus on AI infrastructure and semiconductors rather than the Magnificent Seven, which are underperforming. He details his concentrated portfolio in SOXX, Micron, SanDisk, semiconductor equipment leaders, and networking stocks, citing strong earnings momentum and rising CapEx. He also warns that M7 stocks face headwinds from heavy spending and diminishing shareholder returns.

  • The speaker recommends focusing on the Philadelphia Semiconductor Index (SOXX) as the key benchmark.
  • He holds 30% in SOXX, 20% in Micron, 10% in SanDisk, and positions in Lam Research, Applied Materials, ASML, Lumentum, and Ciena.
  • Earnings estimates for semiconductor stocks are rising sharply, with some seeing triple- or quadruple-digit growth.
  • The M7 (Apple, Microsoft, Amazon, etc.) is underperforming and should be avoided as a group.
  • AI CapEx from big tech continues to increase, supporting the semiconductor supply chain.
  • Market style has shifted from large-cap growth to mid/small-cap semiconductor beneficiaries.
  • The speaker uses a flexible approach, recently pivoting his entire portfolio from diversified holdings to semiconductors.
  • Macro risks (rates, oil, credit) are viewed as manageable, and any correction is seen as a buying opportunity for semiconductor core holdings.
Trade Ideas

Semiconductor index has strong earnings momentum.
The Philadelphia Semiconductor Index (tracked by SOXX) is the best benchmark for the current market because it contains 30 global leaders across the semiconductor value chain (CPU, GPU, memory, networking, equipment) and its earnings estimates are rising sharply. He holds 30% of his portfolio in SOXX.

Memory sector earnings surging, own 20%.
Micron Technology is a core memory holding (20% of portfolio) because the memory segment has a stronger impact within semiconductors, with earnings growth forecast at 455% this year and the stock up 163% year-to-date.

Memory exposure with strong momentum.
SanDisk is held at 10% of portfolio as an added memory exposure, benefiting from the same strong memory demand cycle that drives Micron.

CapEx cycle supports equipment leaders.
Lam Research, Applied Materials, and ASML are global leaders in semiconductor equipment that benefit from sustained capital expenditure by chipmakers. He holds them for steady earnings momentum as CapEx cycles continue.

Data demand boosts networking specialists.
Lumentum and Ciena are niche holdings that specialize in data-solution networking equipment, benefiting from the need to move large amounts of data quickly as AI drives data center expansion.

M7 underperforming, avoid as basket.
The M7 basket (Microsoft, Apple, Nvidia, Alphabet, Amazon, Meta, Tesla) is underperforming the broad market this year, with only 5.9% return vs SOXX up 72%. High capital expenditure needs reduce shareholder returns, making the group unattractive as a whole.
