The Vanguard Group has extended its interest in Norwegian Cruise Line beyond the $1bn mark at a time other major shareholders have been selling stock.

Vanguard, already the second largest investor in the company, has reported a larger stake of 10.14%, up from around 8% back in April this year.

An SEC filing shows the investor to boast 22,312,533 shares in Norwegian, which are worth $1.08bn based in present trading levels.

As TradeWinds reported earlier this month two major shareholders of Norwegian Cruise Line have dumped their remaining holdings.

The Miami owner saw Apollo Global Management and Genting's Star NCLC Holdings sell stock worth $962m.

Vanguard stands alongside T. Rowe Price Associates as the largest shareholders in Norwegian Cruise Line.

Its shares were trading up around 1.5% at $48.57 each on Tuesday.
