Overview
Bank of America is flagging the materials sector as a potential beneficiary of multiple overlapping demand trends, even as the group occupies just 2% of the S&P 500's market capitalization - a share close to its lowest level in 30 years. The bank's chief strategist, Michael Hartnett, argues that a cluster of macro forces could lift materials out of its relative underweight position.
Key drivers highlighted by BofA
Hartnett lists several specific forces that he says support a bullish case for materials:
- Heightened geopolitical competition for natural resources.
- An expanding AI capital expenditure cycle that BofA quantifies at roughly $750 billion and growing.
- Global defense spending approaching $3 trillion.
- A U.S. housing shortage that exceeds 4 million units.
- What the strategist calls a stealth appreciation in the Chinese renminbi.
Strategic positioning - the 'hubris and humiliation' barbell
Hartnett frames materials as a prototypical holding for the ‘‘humiliation’’ side of BofA's ‘‘hubris and humiliation’’ barbell approach. The strategy pairs long exposure to market leaders - notably AI and chip-related names - with beaten-down cyclical sectors that could benefit from the later stages of a nominal GDP upswing. In this construct, materials join other underloved areas such as consumer sectors, China, and U.K. equities in the humiliation bucket. The strategist cautions that ‘‘humiliated bonds won’t work’’ within this pairing, indicating that fixed income is not a suitable complement to the strategy in his view.
BofA's broader 2026 outlook
Beyond materials, the bank expects 2026 outperformers to include commodities, emerging markets, technology, and small and mid-capitalization stocks. BofA characterizes commodities, emerging markets, and small caps as undergoing bullish secular turning points. The bank also points to a marked expansion in U.S. nominal GDP - a 75% surge projected between 2020 and 2027 - and cites consensus views of 5.5% nominal growth for the current year alongside S&P 500 earnings per share forecasts rising about 20%.
Monetary policy dynamics and market structure risks
Hartnett also notes a shift in the balance of central bank policy: for the first time since November 2023, developed market central bank rate hikes are outpacing cuts. He interprets this as a potential source of short-term market vulnerability, specifically flagging the risk of a double-top pattern in the NYSE index in the coming weeks - an index the bank uses as its preferred market barometer - as policymakers move to dampen the nominal expansion.
Recent investor flows
Flow data reported by the bank show a noticeable move to defensive positions in the most recent week. Cash funds recorded inflows of $136 billion - the largest weekly cash inflow since January. Bond funds took in $25.9 billion, extending their run to 54 straight weeks of inflows. By contrast, aggregate stock fund inflows were modest at $2.6 billion.
Regional and sectoral flows were more pronounced. Emerging market equities experienced outflows of $11.6 billion - the biggest weekly withdrawal since January - while China-focused funds saw their sixth consecutive weekly outflow of $9.8 billion, totaling $47.5 billion over that six-week span. European markets endured a four-week outflow streak totaling $11.3 billion. U.S. equities diverged from international weakness, recording a sixth straight week of inflows amounting to $9.3 billion. Consumer-focused funds registered their largest redemptions since December at $1.1 billion.
Sentiment and positioning
BofA's Bull & Bear Indicator climbed to 7.2 from 6.6. While the reading remains within neutral territory, it is edging closer to the bank's 8.0 threshold that signals elevated sell-side caution.
Data and decision-making
BofA underscores the importance of data-driven decision-making for identifying investment opportunities. The bank highlights that systematic analysis of flows, macro indicators, and sector fundamentals can provide clearer signals than gut instinct alone when assembling portfolios for 2026.
Conclusion
Bank of America’s analysis places the materials sector among the most underowned potential beneficiaries of a constellation of macro forces - from AI-driven capital spending to defense budgets and housing shortfalls - while also warning of market structure and policy risks that could complicate near-term outcomes. Investor flows toward cash and bonds in the most recent week reflect heightened risk aversion even as the bank highlights opportunities in commodities, emerging markets, technology, and smaller-cap stocks for the year ahead.
