RDLAX Misses Benchmark as Factor Model Falters in Q1

The Columbia Disciplined Growth Fund (RDLAX) returned -10.50% for Class A shares and -10.44% for Institutional shares in the first quarter of 2026. The benchmark Russell 1000 Growth Index fell -9.78% over the same period. The roughly 72-basis-point gap traces directly to a breakdown in the fund’s stock-selection model.

Factor Model Weakness Drives Q1 Underperformance

The quarter exposed a sharp style rotation. The Russell 1000 Value Index gained +2.10% while growth stocks sold off, led by mega-cap technology names. In that environment the fund’s factor-based selection model recorded its weakest “catalyst theme” reading since inception. Two of the model’s factors detracted from relative returns. Cash flow surprise was identified as the weakest signal. This factor typically rewards companies where operating cash flow beats expectations. In Q1 the market did not reward that signal. Liquidity rotated toward value and defensive sectors, not toward growth-oriented cash flow stories.

The outcome raises a practical question for fund followers. If the factor model’s weights are calibrated for a regime that prizes cash flow momentum, a value-led quarter will naturally penalize the fund. The managers must decide whether to adjust factor exposures or hold through what may prove to be a temporary regime.

Adobe: AI Competition and Softer Billings Trigger Drawdown

Adobe was the top detractor, suffering a double-digit share-price decline. The trigger was softer near-term billings and guidance. The market repriced Adobe on expectations that AI competition would compress its monetization runway. Adobe had outperformed in prior periods, which made the valuation reset more severe.
