iShares National Muni Bond ETF rises 0.18% to $103.43, up 1.06% for the week

Four straight weekly gains in a national muni bond fund points to steady demand for tax-exempt fixed income rather than a risk-on rotation, and the approach toward the prior September close is the level that frames the near term. The move matters most for income-oriented holders of muni exposure, where weekly consistency often reflects rate expectations more than fund-specific news. Whether the streak extends past that September high, or stalls there, is the open question worth watching.
