Healthcare ancillary gains, AGL faults to drag, Rio underwhelms, News set to enter betting The Ramsay tide lifted all boats in the healthcare sector with the likes of Resmed (ASX: RMD) and Sonic (ASX: SHL) also gaining more than 2 per cent each on the knowledge that private equity is clearly focused on the sector. Shares in AGL (ASX: AGL) reversed, falling 3.2 per cent after management confirmed the struggling Loy Yang A Power Station would remain out of service until at least 1 August due to a continuing electrical fault at the plant; this will likely send energy prices higher in winter. Iron ore miner Rio Tinto (ASX: RIO) weakened by 2.8 per cent after flagging a "challenging" first quarter of production but keeping guidance at 320 to 335 million tones despite facing labour and workplace challenges.
