Oil resumes slide after brief rebound on short-covering

(Reuters) - Global crude prices fell again on Thursday, a day after a short-covering rally, as traders placed new bets that the market would resume a six-month rout on worries about a supply glut.

In early trade, oil extended gains from the previous session, when short-covering lifted prices more than $3 a barrel.

But in late morning trade in New York, benchmark Brent and U.S. crude fell more than $1 a barrel to session lows. They then retraced some losses, with Brent down around $60 a barrel while U.S. crude was down near $55.

"We're continuing to search for a bottom, and might even see another significant drop before the year-end," said Gene McGillian, an analyst at Tradition Energy in Stamford, Connecticut.
