Inflation concerns pressure global equities, while earnings and news momentum still provide support

BofA's high-frequency monitor shows global equities fell 0.6% last week, with the U.S. holding up relatively better and Energy and Tech Hardware leading; however, rising inflation could prompt central banks to hike rates, which is the main risk.

Report interpretation

Overview

This report is BofA Securities' global quantitative high-frequency monitor released on 2026-05-18. It focuses on price momentum, earnings momentum, and news momentum across global equities, regions, sectors, styles, and themes. The core conclusion is that global equity markets pulled back on inflation concerns, but the earnings cycle remains solid, Global News Pulse has improved, and AI- and technology-related themes continue to provide support.

Core views

Global equities fell 0.6% last week, mainly because inflation worries offset optimism from earnings and AI themes. Regionally, the United States rose 0.2% and led, while Emerging Markets fell 2.5% and lagged. At the sector level, Energy and Tech Hardware performed best, while Utilities, Materials, and Real Estate saw larger declines. At the theme level, Space and Renewable Energy led last week, but the Triple Momentum composite ranking still shows Gold, Rare Earths, and Robotics as the strongest, with Luxury Lifestyle and SaaS the weakest. The report warns that if inflation pushes central banks to resume rate hikes, it could become the main headwind for the market.

Analysis framework

The report uses a high-frequency quantitative monitoring framework that combines market performance, breadth, earnings revisions, news pulses, style, region, country, sector, and theme rankings to assess global equity markets. The Triple Momentum framework cross-checks earnings momentum, price momentum, and news momentum to evaluate the relative standing of themes, sectors, regions, and individual stocks.

Methodology notes

  • Quantitative momentum frameworkTriple Momentum

    Composite ranking of earnings momentum, price momentum, and news momentum

    The report uses Triple Momentum to compare global themes, sectors, regions, countries, and individual stocks. Charts typically place earnings momentum on the y-axis and price momentum on the x-axis, while color or bubble size represents news momentum, allowing identification of the assets with the strongest or weakest composite momentum.

  • Earnings revision frameworkEarnings Revision Ratio

    Ratio of the number of stocks with upward earnings revisions to those with downward revisions

    Using IBES consensus estimates, the report measures on a monthly basis, or month-to-date, the ratio of stocks with upward revisions to those with downward revisions in earnings forecasts, in order to track earnings expectation trends across global regions, sectors, and styles.

  • News sentiment frameworkGlobal News Pulse / NewsAlpha

    High-frequency indicator based on news mentions and news momentum

    The report uses Global News Pulse as an indicative measure to track changes in the news backdrop across regions, sectors, countries, and themes. It is not designed as a benchmark and should not be used as a performance benchmark for financial instruments.

Impact & implications

The key investment takeaway is that the market is not broadly deteriorating: the earnings cycle and news backdrop still offer support, but the advance has become more concentrated, breadth has weakened, and inflation and rate risk have again become the key variables pressuring valuations and risk appetite. In the near term, investors may want to focus on Energy, Tech Hardware, Semiconductors, and the stronger Triple Momentum themes of Gold, Rare Earths, and Robotics, while watching for downside risk in high-valuation, rate-sensitive, and weaker-momentum themes.

Risks

  • Continued inflation upside and the resulting risk of central-bank rate hikes is the main market risk explicitly highlighted in the report.
  • Weaker market breadth, with the equal-weighted index lagging the market-cap-weighted index by a wide margin, suggests that the rally may be overly concentrated.
  • Quantitative screens and news pulses are indicative measures only and should not be treated as benchmarks or as measures of financial instrument performance.
  • Short-term trading ideas and quantitative rankings may not be suitable for all investors, and related strategies may incur significant losses.
  • The securities or financial instruments discussed in the report may be subject to market risk, liquidity risk, foreign-exchange risk, and derivative risk.
  • BofA Securities and its affiliates may have business relationships or potential conflicts of interest with the issuers discussed in the report.

What to watch

  • Whether inflation data continues to reinforce expectations for central-bank rate hikes.
  • Whether the global earnings revision ratio keeps improving, and in particular whether the recent three-week improvement in the Value style can continue.
  • Whether the performance gap between the ACWI market-cap-weighted index and the equal-weighted index continues to widen.
  • Whether Triple Momentum leadership in Energy, Tech Hardware, and Semiconductors remains intact.
  • Whether the composite momentum in Gold, Rare Earths, and Robotics can translate into subsequent price performance.
  • Whether weak-momentum themes such as SaaS and Luxury Lifestyle continue to lag.
  • Changes in Global News Pulse at the country, sector, and theme level, especially in regions with elevated news pulse such as Mexico and Taiwan.
