Chi-X hoses down claims it may close down within a year BOUTIQUE stockbroker Evans & Partners has openly canvassed the prospect of Chi-X Australia closing its doors within 6-12 months as the rival exchange operator wrangles with the Australian Securities Exchange over market share figures. Evans & Partners, which is not on Chi-X's panel of brokers, said in a note to clients that Chi-X had failed to reach its assumed breakeven market share of 10 per cent to 15 per cent since its November 2011 launch.
