How did U.S size and style leadership evolve in 2025?
Prediction: Large caps could outperform small caps, mirroring 2017, where easing regulatory expectations initially boosted smaller companies before rate dynamics reasserted themselves.
Outcome: Right
The B1000 Index is up 17% this year, outpacing the B2000 Index’s 14% gain. Market moves in the US have largely been the result of strong gains in some of the largest names such as the Magnificent 7.
Prediction: Growth could continue to outpace Value, as it did in 2017.
Outcome: Right
The B1000 Growth Index advanced 17.3%, beating the B1000 Value Index at 16.9%. The equity style leadership pattern from 2017 repeated, with investors rewarding earnings durability and high-quality balance sheets throughout bouts of market volatility.
Which sectors and innovation themes led the market in 2025?
Prediction: Materials might benefit from tariff dynamics, similar to the strong performance from that sector in 2017.
Outcome: Wrong
Instead of leading, the Materials sector lagged. The Bloomberg 500 Materials (B500MA) Index returned just 11.3%, trailing the broad B500, while Communications (B500C) was the standout at +33.3%. Tariff expectations and industrial-metal dynamics did not repeat the 2017 pattern, underscoring the importance of distinguishing between tariff speculation versus tariff implementation.
Which innovation themes led or lagged equity markets in 2025?
Prediction: Solar, digital finance, and broader innovation-driven themes could experience strong performance—reflecting their 2017 surge.
Outcome: Mixed to Right
- Solar (BSOAP): Right. Up 33.9%, closely tracking 2017’s strong results. Even though the underlying solar industry still faces challenges, investors responded to both positive catalysts and changing expectations throughout the year.
- Future of Finance (BFFAP): Right. Up 46.1%, echoing 2017’s structural-disruption enthusiasm. Many crypto linked stocks, such as Robinhood and Cipher Mining, have benefited from increased regulatory clarity and stronger investor participation in digital asset markets.
- Digital Payments (BDPAP): Wrong. While the index is up 15.8% this year, it trailed global equities. Payment companies have been under antitrust scrutiny and litigation over swipe fees and merchant network practices. Some investors also viewed the loosening of crypto regulations as increasing the risk of disruption to traditional card payment models.
Which global regions led equity performance in 2025?
Prediction: Despite early selling pressure, Emerging Markets could ultimately outperform—just as it did in 2017— raising questions on whether trade-war fears were overstated.
Outcome: Right
Both the Bloomberg Emerging Market (EM) Index and the Bloomberg China (CN) Index outperformed the B500 by over 10%. Even developed markets (DM Index) beat the U.S. by 2.5%. Fears of renewed trade tensions proved excessive, much as they did in 2017. Moreover, with U.S. equity concentration remaining a key concern for many investors, demand for additional portfolio diversification has strengthened. In fact, of the 47 countries included in the Bloomberg World Index (WORLD), only 5 produced negative returns in 2025.
How did currency movements influence equity returns in 2025?
Prediction: In 2017, the dollar weakened against other major currencies, as many investors were concerned about U.S. fiscal and monetary policy.
Outcome: Right
The DMXUHU (hedged) Index gained 20.5%, trailing the unhedged DMXUN Index at 28.1%. Even with post-election dollar strength (+4% vs EUR, +3% vs JPY and GBP), the return benefit of foreign-currency exposure mirrored the pattern seen in 2017’s weaker-dollar environment. Uncertainty related to U.S. fiscal policy has left some investors less inclined to hold dollar assets.
Which equity factors mattered most in 2025?
Prediction: Companies with strong fundamentals either through core-earnings strength (BCORE) or disciplined capital returns (BSHARP) would attract greater investor interest.
Outcome: Mixed
The market leaders of 2024 largely maintained their strength into 2025, resulting in a strong year for the momentum factor. Although conventional factor-based methods outside of momentum offered limited excess return, some alternative or updated factor approaches demonstrated more meaningful results.
- BCORE: Right. Up 27.0%, confirming that investors rewarded earnings resilience in a volatile environment. The index consists of names like Applovin, which reported strong financial results, with big year-over-year revenue growth and expanding profitability.
- BSHARP: Wrong. While the index is up 9%, its muted relative performance may reflect investors preference for higher growth names over dividends and buybacks.
As 2025 draws to a close, markets have rewarded investors who recognized the familiar rhythms reminiscent of 2017, a period where patience, discipline, and thoughtful thematic positioning proved their worth.
What will 2026 bring for equities? Will leadership finally broaden? Will investors grow more confident in an environment where moderate growth and steady policy can support continued returns? And will security selection and thematic exposure regain prominence as dispersion picks up? Look out for our 2026 equity outlook in January, where we will weigh these questions and highlight the themes that are poised to shape the year ahead.
