* STX Group shares tumble, banks also drop
* Autos hit by profit-taking after recent gains
SEOUL, June 5 (Reuters) - Seoul shares slid to their lowest close in almost four weeks on Wednesday, as concerns that the U.S. central bank might consider scaling back its stimulus programme prompted selling in growth-sensitive auto and technology stocks.
STX Group shares tumbled following media reports that shipping affiliate STX Pan Ocean will soon enter court receivership, with STX Pan Ocean becoming the biggest percentage loser on the KOSPI.
The Korea Composite Stock Price Index ended down 1.5 percent at 1,959.19 points, moving further away from the key 2,000-point level and marking its lowest close since May 13. South Korean financial markets will be closed on Thursday for a public holiday.
"The market was a bit alarmed by growing speculation the U.S. Federal Reserve may slow its stimulus programme," said Y.S. Rhoo, a market analyst at Hyundai Securities.
"There are questions about the prices of stocks and bonds ... whether they are a bit inflated," he said.
The U.S. Federal Reserve is poised to evaluate and potentially make changes to its massive stimulus, a top Fed official who is critical of the Fed's bond-buying programme said on Tuesday.
