1110(Dow Jones) OZL sp fall this morning could be explained by a squaring of long positions by margin lenders, as a few have decided not to support such position for their retail customers, according to a market participant,who didn't want to be named. So share fall is more technical than due to any renewed speculation on OZ's ability-or not-to arrange debt extension. Last down21% or 12.5c to 46c. End quote.
