* Monte Paschi shares jump around 20 pct

MILAN, March 5 Shares in Italy's third biggest
lender Monte dei Paschi di Siena soared 20 percent in
heavy volume on Wednesday, prompting speculation the bank's top
investor may have found a buyer for part or all of its stake in
Three sources close to the situation and a financial source
said the banking foundation that has just over 30 percent of the
lender could have sold a stake. None of them however said they
knew or were certain this had happened.
The foundation and the bank declined to comment.
Monte dei Paschi shares closed 19.2 percent higher at 0.22
