The company, which is in 21 trendlyne stock screeners, saw its net profit YoY grow five-fold, and also saw operating profit margins expand to 34.1% compared to 12.62% in the June quarter the previous year.  Institutional, FII and mutual funds increased their shareholding between the March and June quarters.  

The aluminium firm noted that its Damanjodi unit is now the lowest cost producer of alumina worldwide, helping boost operating margins and profits. At the same time, NALCO's alumina sells at more than 10% premium over the average CRU index. The company's share price is rising on high volumes today.
