"We don't think that's something for us," Dijsselhof said in an interview on Wednesday when asked about Allfunds. "We've also had a look at it, but not our cup of tea."

Dijsselhof said SIX is in contact with private equity firms, including Allfunds largest shareholder Hellman & Friedman, as it scans the market for possible acquisitions.

The comments come two months after Reuters reported that SIX, the operator of the Swiss and Spanish stock exchanges, was in the early stages of exploring a takeover of Amsterdam-listed Allfunds.
