The chief executive officer at Instinet, the agency broker owned
by Japanese investment bank Nomura, is preparing to step down
later this year, according to people familiar with the
mater. 

Instinet CEO Jonathan Kellner joined the company in 2007 as its
head of US sales trading and took on the top position at the firm
in 2014.

Recently, Financial News reported that Ralston Roberts, a
electronic trader executive from Goldman Sachs,was joining
Instinet as chief operating officer. Roberts is cited as a
potential replacement for Kellner, the people said. 

A spokesperson for Instinet declined to comment. 

Elsewhere at Instinet,
the firm has been scooping up a number of former KCG
employees, including William Wiley, as head of
strategy; Brian Bulthuis, as an executive director; and Denise
Fiacco in the quant trading strategy group. 

Many of those hires were part of a broader effort at the
firm to broaden its focus on quant research and development to

improve the quality of trade execution. 

Instinet provides algorithmic trading products, trading
analytics, and other execution services, working out of offices
in New York, London, San Francisco, Edinburgh, and Hong
