| Factors Affecting Performance [Text Block] | Management’s Discussion of Fund Performance
SUMMARY OF RESULTS
Fundamental All Cap Core Fund (Class A/JFCAX) returned 24.58% (excluding sales charges) for the year ended July 31, 2024. The U.S. economy’s resilience, stabilized and potentially lower interest rates, plus investor enthusiasm for artificial intelligence (AI) helped fuel the market and fund’s gain.
TOP PERFORMANCE CONTRIBUTORS
The information technology sector was among the strongest performers in the portfolio in the annual period | A sizable stake in semiconductor company NVIDIA Corp., a leader in AI, surged, boosting the fund’s result.
The financials sector also stood out to the upside | An allocation to private equity company KKR & Co., Inc., which rallied sharply, notably aided fund performance.
The consumer discretionary sector further boosted the fund’s result | A sizable position in e-commerce leader Amazon.com, Inc. posted a steep gain.
TOP PERFORMANCE DETRACTORS
Consumer staples stocks generated a weak return in the fund | Of note was a position in natural foods and organic personal products company Hain Celestial Group, Inc., which plunged during the period.
Certain consumer discretionary stocks notably detracted from performance | They included recreational vehicle company Polaris, Inc. and luxury winter clothing company Canada Goose Holdings, Inc., each of which fell sharply.

| Factors Affecting Performance [Text Block] | Management’s Discussion of Fund Performance SUMMARY OF RESULTS Multi-Asset Absolute Return Fund (Class A/JHAAX) returned 3.18% (excluding sales charges) for the year ended July 31, 2024. The most significant factors affecting fund performance during the period included a meaningful rally in global equity markets, led primarily by growth-oriented stocks in developed markets, and a shift from interest-rate increases to easier monetary policy by many of the world’s central banks—with notable exceptions in the U.S. and Japan. TOP PERFORMANCE CONTRIBUTORS Developed market stocks | Equities in developed countries were among the best performers, adding to the fund's performance. Cash | A small cash and cash-equivalents position provided a noteworthy level of interest income. Credit-related bonds | Selected, tactical positions in credit contributed modestly to performance. TOP PERFORMANCE DETRACTORS Defensive equity strategy | This strategy, which includes long positions in lower-risk stocks and short positions in broad equity indexes, detracted from performance as lower-risk stocks underperformed the broader market. Foreign currency exposure | The fund’s defensive long/short positions in high-quality foreign currencies were a drag on performance, due in large part to the Japanese yen’s depreciation against most major currencies. The views expressed in this report are exclusively those of the portfolio management team at Nordea Investment Management North America, Inc., and are subject to change.
