Merchant banking firm Grail Partners has bought a minority stake in Sausalito, Calif.-based quantitative hedge fund shop Creighton Capital Management.Details of the transaction were not disclosed, though Grail managing partner John Siciliano will join Creighton Capital’s management committee.

“Their strategy is based on a statistical model of equity markets which reflects a very different approach than the typical factor-based strategies of most quant managers,” Siciliano said. “We look forward to assisting Creighton Capital in bringing their strategies to a marketplace that is demanding an alternative to traditional quantitative investment firms.”

Creighton Capital was founded in 2004 by its namesake, James Creighton, a former global chief investment officer of Barclays Global Investors, Northern Trust and Deutsche Asset Management.
