LISBON, May 29 (Reuters) - ** Shares in Portuguese pulp
producer Altri ALSS.LS slump 5.3% to 5.855 euros, as ongoing
trade tensions between Washington and Beijing are hurting paper
sector.
** Altri leads decliners on Lisbon's PSI20 .PSI20 index,
down 1.25%.
** "The pulp sector has been under strong pressure, with the
trade war decreasing investor demand," says Carla Maia, a trader
at XTB brokerage in Lisbon.
** After rising nearly 24% in the first three months of the
year, Altri shares have changed course, shedding more than 15%
of their value since the beginning of April.
