SINGAPORE, Aug 5 (Reuters) - Singapore"s DBS Group Holdings (DBSM.SI) flagged strong loan growth and weaker credit costs after posting a 37% jump in quarterly net profit, as Southeast Asia"s largest lender benefited from a rebound in its mainstay home market.

Bernstein, commenting on DBS. DBS shares rose as much as 1.2% to a record S$30.95 in a flat market. The stock is up 23% so far this year.
