Shares of Jet Airways today tanked more than seven per cent on bourses on Monday, eroding Rs412 crore from its market capitalisation, amid reports that Etihad may revise its deal to buy a stake in the Indian carrier.

According to reports, Etihad Airways Chairman Sheikh Hamed bin Zayed al-Nahayan said the Abu Dhabi-based carrier needs to revise its deal to buy a stake in the Indian carrier and it was too soon to say when a final agreement between the two carriers would be struck.

Reacting to the news, shares of the company opened on a weak note and then lost further ground and touched  intra-day low of Rs563.30 on BSE, lower by 8.90 per cent from its last closing price.

At the end of today's trade, the scrip however, gained some lost ground and was trading at Rs570.75, down 7.70 per cent from its previous closing price.

In just a single day trading, the company lost a Rs412 crore from its market worth. At the end of today's trading, the stock's market capitalisation decreased to Rs4,927 crore, from Rs5,339 crore in the previous trading session (February 15).

On the National Stock Exchange as well, the stock opened at Rs615 and touched intra-day low of Rs563.20, down 8.85 per cent from its previous closing price.

At the end of trade, the stock was trading at Rs573, down 7.27 per cent from its last closing price.

Etihad is likely to buy 24 per cent equity in Jet Airways valued at about Rs1,800 crore. If the deal is carried through, it would be the first investment by a foreign carrier in an Indian airline.
