The US Federal Reserve’s (Fed) decision to lower the federal funds rate by 0.50% at its September meeting, as well as the tone of the accompanying statement, reflected the Fed’s confidence in its ability to continue to ease policy in the future. Natural resources equities, despite overall gains, trailed the broader equity markets. ■ Among natural resources sectors, metals & mining stocks were strong performers for the period. Several energy exploration & production and midstream energy companies also reported strong gains. ■ Relative to the Lipper Global Natural Resources Index, the Fund’s performance was led by its exposure and stock selection with its metals & mining stocks as well as stock selection in the energy sector.
