(P1) The materials sector is poised for a long-term upward trend, according to a new report from Bank of America, as a confluence of factors including AI-driven capital spending and a 30-year low valuation create a compelling investment case. The sector currently represents just 2% of the S&P 500's total market capitalization.
(P2) "Global geopolitical competition for resources, the AI capital expenditure boom, surging defense spending, and the US housing shortage are collectively pushing the materials sector to a long-term upward inflection point," Michael Hartnett, chief investment strategist at BofA Securities, said in a note to clients.
(P3) The call is underpinned by several large-scale economic trends. The report notes that capital expenditures on AI infrastructure have reached $750 billion and continue to climb, while global defense spending is approaching $3 trillion. In the US, a housing deficit of over four million units is expected to drive construction demand.
(P4) Hartnett recommends a "bubble barbell" strategy, pairing "fever assets" like AI and chip stocks with "humiliated assets" such as undervalued cyclicals. Within this framework, the materials sector is presented as the optimal counterweight to the current chip craze, with technical indicators like the steel ETF (SLX) testing its 2008 pre-financial crisis highs.
The Barbell Strategy in a "Bubble-Stagflation" Market
Hartnett's "bubble barbell" strategy is designed for what he terms a "bubble-stagflation" environment. He notes the rare simultaneous occurrence of stocks and gold both posting double-digit annual gains for four consecutive years. Historically, this combination has only appeared during periods of war, peace, bubbles, and stagflation, suggesting the buildup of deep structural risks.
The strategy involves simultaneously holding both high-growth, high-risk assets and deeply undervalued, cyclical assets. This allows investors to participate in the upside of the current AI-driven market while hedging against a potential downturn with assets that are out of favor and have a significant valuation cushion.
AI Capex and Industrial Demand
The AI boom is a significant, if indirect, driver for the materials sector. As hyperscale data center construction accelerates, the demand for raw materials from copper for wiring to aggregates for concrete is expected to increase. Bank of America has highlighted companies like Caterpillar (CAT) as beneficiaries, with the machinery giant in a "sweet spot" to gain from increased industrial activity.
While the top 10 AI-related stocks now account for a concentrated 40% of the S&P 500's market value, a level approaching historical bubble peaks, the investment in the underlying infrastructure is just beginning. This creates a tangible demand floor for the physical assets and raw materials supplied by the materials sector.
