Report Industry Investment Rating - Aluminum: Cautiously bullish - Alumina: Cautiously bearish - Aluminum alloy: Cautiously bullish [10] Core Viewpoints - At the transition between the off - season and peak season of aluminum consumption, macro and micro factors resonate. The Fed's September interest - rate cut expectation is rising again, and the overall non - ferrous metals market is strongly oscillating. The aluminum supply side is stable, and consumption is shifting from the off - season to the peak season. The long - term logic of limited supply and stable consumption growth remains unchanged. For alumina, the supply is in continuous surplus, and attention should be paid to the decline rate of spot prices and potential short - term disturbances. For aluminum alloy, consumption is transitioning from the off - season to the peak season, and seasonal repair trends are emerging [6][8][9] Summary by Related Catalogs 1.
