Shares of Hindalco Ltd., the Aditya Birla Group company, are the top losers on the Nifty 50 index on Thursday, November 7, after its unit Novelis, reported its quarterly results late Wednesday night. 

The bigger factor that resulted in the fall in share price was the fact that Novelis withdrew its short-term EBITDA per tonne guidance of $525. 

For the quarter gone by, Novelis' EBITDA per tonne stood at $498, down from $519 during the same quarter last year and $525 in the June quarter. 

Additionally, unfavourable mix from lower automotive shipments, along with less favourable metal benefit from higher scrap prices also impacted the company's EBITDA per tonne. 

The management of Novelis expects headwinds to persist in the current as well as the March quarter due to increasing aluminium scrap prices. 

Shares of Hindalco are trading 8% lower at ₹651.45. The stock is down over 15% from its recent peak of ₹772. The recent fall has trimmed Hindalco's year-to-date gains down to 7%.
