(Reuters) -Australia's Coles Group on Tuesday posted a 4.8% rise in full-year profit, helped by increased supermarket, sales but missed market expectations, sending the shares down nearly 4%. The country's No. 2 grocer reported a net profit after tax of A$1.10 billion ($705.54 million) for the year ended June 30, compared with A$1.05 billion a year earlier. Analysts at Jefferies called the results "disappointing", while those at UBS expect further labour and operational costs to be headwinds for the company in future.
