**STX SURGES ON REPORT OF LIKELY UNIT STAKE SALE**
Shares in STX Corporation rose more than 5 percent following a local media report that the cash-strapped company was close to a deal to sell a controlling stake in Singapore-listed affiliate STX OSV Holdings.
STX Corp in August chose Italian government-owned ship builder Fincantieri SpA as the preferred bidder for a 50.8 percent stake, valued at about $800 million.
A STX Corp official said on Tuesday that the stake sale appears imminent but declined to comment further.
