Holdings data comes from the latest SEC Form N-PORT-P filing for this fund, covering the reporting period ended Feb 28, 2026. Market values are reported in US dollars, and each weight represents the position's share of reported fund assets. Cash, derivatives, and rounding can mean displayed weights do not total 100%. Funds rebalance and file on a schedule, so this page may not reflect intraday or post-filing changes.
