These Were the Best-Performing Asset Classes in May. Can They Continue to Lead?
May saw broad gains across asset classes, led by U.S. equities. The Vanguard Total Stock Market ETF (VTI) rose 5.2% and the S&P 500 gained 5.3%, extending its Oct. 2022 bull market. Tech outperformed: the Nasdaq-100 (QQQ) climbed 10.6%, with Micron +89%, AMD +41%, and Oracle +40%. Developed international stocks rose 4.3% (VEA) and emerging markets 1.6% (VWO). Commodities fell 7.5%, with crude oil down 12.2%.
Reinforces momentum/relative-strength positioning in Nasdaq/large-cap tech exposure.
Nasdaq-100 proxy QQQ is cited up 10.6% in May, with mega-cap tech strength attributed to AI infrastructure spending.
Near-term positive bias for QQQ-linked trades if AI capex narrative persists.
Background
The piece reviews May’s best-performing asset classes and argues that mega-cap tech/semis should keep leading into June due to AI data-center infrastructure spending.
Why it matters
It provides a directional narrative (AI capex → semis/equipment/software) but does not cite new company-specific events (earnings, guidance, contracts, trials).
Market relevance
Primarily a risk-on/momentum read-through for U.S. tech and AI-linked semis; limited new tradable information beyond performance attribution.
Market effects
Reinforces AI infrastructure capex read-through across semis (memory, compute) and equipment, supporting a tech/semis momentum trade.
Developed-market outperformance is attributed to semiconductor exposure (Korea + ASML), implying relative strength in those regions.
AI capex narrative is presented as a global driver for semiconductor supply chains, while commodities (oil) are a drag.
Alternative perspectives
The article is largely a momentum recap; the very large MU/AMD/ORCL run-ups raise mean-reversion risk if AI capex expectations cool.
No mention of valuation, earnings revisions, or supply/demand constraints; without new catalysts, continuation may be fragile and sentiment-driven.
