Crude oil futures extended gains in early Asian trade on Monday on short-covering demand, with both Brent and U.S. crude near$32.50 a barrel. Oil prices surged 10 percent on Friday, one of the biggest daily rallies ever, as bearish traders who had taken out record short positions scrambled to close them, betting the market’s long rout may finally be over. Brent (LCOc1) had climbed 33 cents a barrel to $32.51 as of 08:37 p.m. EST on Sunday after touching $32.69 a barrel earlier the session.
