FRANKFURT (Reuters) - Capital Group has increased its stake in Commerzbank <CBKG.DE> to 4.82% from 2.93%, a regulatory filing showed, making the Los Angeles-based investor one of the German bank's largest shareholders.
Capital Group earlier this month bought a big stake in rival Deutsche Bank <DBKGn.DE>, marking a vote of confidence in that troubled lender.
Shares in Commerzbank briefly jumped on the news of the Capital investment, making up some of its earlier losses, but were still trading 5% lower early afternoon in Frankfurt amid a global selloff.
Commerzbank declined to comment. Capital Group did not immediately respond to a request for comment.
The activist investor Cerberus also owns a big stake in both banks.
Both Commerzbank and Deutsche Bank were in talks to merge last year but called off the negotiations. Cerberus had been pushing for a merger, people with knowledge of the matter said at the time.
