Australian retailing major Coles Myer has come under scrutiny this week. While analysts are receiving mixed reports about the company's e-tail performance, institutional investors are asking - who's the boss? The group's eponymous website, e-colesmyer , turned over A$142m (US$71.8m) in the six months to 31 December last year. Managing director Jon Wood has since hinted however that some of its operations are unprofitable.
