BUENOS AIRES, July 29 Argentina's MerVal stock
index reversed losses and rose 5.1 pct on Tuesday on
increased optimism about last-minute debt talks in New York
aimed at avoiding an Argentine default, traders said.
Argentine negotiators were expected to hold further talks
with a mediator on Tuesday. Meanwhile, holders of Argentina's
euro-denominated exchange bonds urged a U.S. judge to issue a
last-minute stay on his debt ruling that risks toppling the
country into default on Thursday.
