The current technical setup near resistance requires monitoring for breakout confirmation.
XLU trades at $41.39, up 0.58% today, with technical indicators showing a mixed but overall bullish signal. The ETF recently hit 52-week lows around $39.13 amid sector-wide pressure from rising interest rates.
