Chief Executive of Australian property developer Multiplex Ltd Andrew Roberts speaks during a news conference in Sydney August 18, 2005. Roberts announced the company had recorded a lower-than-expected annual profit, cut its 2006 forecast and flagged more cost blowouts at its troubled Wembley stadium project in Britain. Investors, already burned by three profit warnings this year, initially axed as much as seven percent off Multiplex shares, but rebounded in later trading to just two percent down which is still the worst performer among Australia's top 200 stocks this year.
