Rebon, a Dutch investment fund, and its wholly owned subsidiary Cobra, has bought a 9.9% stake in Commerzbank, Germany's fourth largest investment bank.

Martin Kohlhaussen, Commerzbank's chairman was quick to point out that Rebon's investment would help to put a stop to rumours of a takeover of Commerzbank by another bank. He said that Rebon's stake would add to shareholder stability.
