Sept 30 (Reuters) - Cboe Global Markets ( CBOE ) has

rehired industry veteran Rob Hocking to lead its derivatives

business, it said on Tuesday, as the exchange operator

strengthens its ranks under new CEO Craig Donohue.

Hocking will succeed Cathy Clay, who is leaving the

Chicago-based company for a new opportunity. He will join the

firm's executive leadership team and report to Donohue, who took

helm at Cboe in May.

Prior to this, Hocking, who comes with more than two decades

of experience in global derivatives market, had worked as the

global head of product innovation at Cboe.

The company's derivatives business houses its futures and

options markets in the U.S. and Europe, as well as trading

products such as the S&P 500 index options and VIX franchises.

Cboe has also hired industry veteran Brian McElligott to

lead its data business. He had previously spent more than a

decade at derivatives exchange operator CME Group ( CME ).

Cboe's data business has registered robust growth over the

past couple of quarters, driven by strong international demand.

Roughly 45% of the new recurring sales were from outside the

U.S. in the second quarter.

Hocking and McElligott will be based in Chicago and start in

their new roles on October 1.
