Harbor AlphaEdge ETF Underperforms in Q1 as Value Lags Growth

Harbor AlphaEdge Large Cap Value ETF posted a 0.68% return in the first quarter of 2026, trailing both of its primary benchmarks, the fund's commentary showed. The underperformance comes as large-cap growth stocks outpaced value by a wide margin, reversing the trend that favored cheap stocks through much of 2025.

The fund uses a quantitative process that weights valuation, momentum and quality factors. A tilt toward financials and energy – sectors that lagged the S&P 500 in the quarter – may have contributed to the shortfall. Recent stock market analysis highlighted the ongoing rotation into mega-cap technology names, which the ETF's model underweighted.

Harbor Capital did not immediately release sector-level attribution. The full commentary, including top contributors and detractors, is typically published within two weeks after quarter end.

The broader context: the S&P 500 rose roughly 2.5% in Q1, while the Russell 1000 Value index gained about 1.8%. The ETF's return of less than half those benchmarks will prompt scrutiny of the quant model's current factor exposures. For a fund built on systematic factor timing, the Q1 result tests the premise that a rules-based approach can consistently outperform across shifting market regimes.

The fund's strategy documentation notes that the AlphaEdge process rebalances quarterly. The next rebalance occurs in early April, incorporating updated factor signals. That will be the first chance to see whether the model shifts its sector and style bets in response to the growth-heavy environment.
