The macro factor driving PWB forward is straightforward: enterprise spending on artificial intelligence infrastructure remains robust, and the companies building that infrastructure are printing money.

The JPMorgan Active Growth ETF ( NYSEARCA:JGRO) delivered a 14.2% return over the past year, trailing the S&P 500's 17.9% gain by nearly 4 percentage points. For investors paying a 0.44% expense ratio for active management, underperformance raises a key question: what should you watch to understand whether this fund can close the gap?

This concentrated approach explains both the fund's recent gains and its vulnerability to tech sector rotation. When Tech Dominance Becomes a Double-Edged Sword The biggest factor shaping JGLO's future is whether mega-cap technology stocks can sustain market leadership or if returns are broadening.
