The former global co-head of equities at Nomura and the ex-global co-head of equities distribution at JP Morgan have teamed up to launch the Asian arm of interdealer broker Mariana Capital Markets, Financial News can reveal.

Rachid Bouzouba, until March 2011 the global co-head of equities at Nomura, has joined Mariana as a founding partner, along with Adrian Valenzuela, who most recently worked at Barclays and before that was global co-head of equities distribution at JP Morgan.
