LONDON, Feb 1 (Reuters) - Raw sugar futures edged up on Thursday, steadying after falling sharply in the prior session when speculative short covering came to a sudden halt, while New York cocoa hovered near an eight-week high.
* March raw sugar was up 0.02 cent, or 0.2 percent, at 13.25 cents per lb by 1150 GMT.
* Prices tumbled more than 3 percent on Wednesday, as a recent bout of speculative short covering petered out, giving way to long liquidation, dealers said.
* "Investors obviously stopped buying back their short positions yesterday," said Tobin Gorey of the Commonwealth Bank of Australia. "A four-day recovery was lost in little more than four hours."
* The market was boosted this week by data showing speculators had extended their net short positions to a record, suggesting an aggressive selling spree may have run out of steam.
* But, with the short covering over for now, dealers said the focus was back on a large global surplus expected in the 2017/18 season, amid strong production in the EU, Thailand and Pakistan.
* March white sugar rose $0.40, or 0.1 percent, to $352.80 per tonne.
* Dubai's Al Khaleej Sugar Refinery, the world's largest port-based refinery, produced 1.8 million tonnes of white sugar in 2017, state news agency WAM said on Thursday.
* March New York cocoa climbed $6, or 0.3 percent, to$2,002 a tonne, hovering below an eight-week top of $2,012 touched in the prior session.
* Prices have recently been boosted by a weaker dollar and a stronger British pound, which has improved the arbitrage and encouraged buying in the New York market, dealers said.
* Currency moves continued to support New York prices on Thursday, but dealers noted the market remained vulnerable technically.
* "Despite sentiment being on the upside, settlements have been off the highs," Sucden Financial technical analyst Geordie Wilkes said in a note. "This suggests (a) tentative tone, and could prompt a test of trend support."
* March London cocoa was unchanged at 1,399 pounds a tonne.
* March robusta coffee was down $4 or 0.2 percent, at $1,743 a tonne.
* Indonesia's 2018 coffee output is seen at around 500,000 tonnes, down by about a fifth from a year earlier, the Association of Indonesian Coffee Exporters and Industries (AICE) told Reuters.
* The country's coffee bean exports from Lampung province plunged 71 percent in January year-on-year.
* March arabica coffee fell 0.15 cents, or 0.1 percent, to $1.2170 per lb. (Reporting by Ana Ionova; Editing by Susan Fenton)
