Borse Dubai plans to sell part of stake in the Nasdaq in a deal potentially worth some $1.6 billion

A Dubai sovereign wealth fund that's the single-largest shareholder in the Nasdaq stock index plans to sell a third of its shares in the exchange, a deal potentially worth some $1.6 billion that saw the value of the firm fall in aftermarket trading Wednesday. The announcement from Borse Dubai, owned by the Investment Corp. of Dubai, would make it the second-largest holder in the Nasdaq, a technology-heavy exchange that's one of the three main indexes in the United States. “Today’s offering is being conducted to enhance the capital structure and liquidity within the Borse Dubai Group," said Essa Kazim, chair and CEO of Borse Dubai, in a statement released after the Nasdaq closed Tuesday.
