Australian shares fell on Tuesday The Australian share market Tuesday suffered its biggest one-day fall in three weeks, with financials and consumer discretionary stocks leading broad-based declines as the European sovereign debt crisis spread to Spain and Italy. Traders said a euro group statement failed to halt speculation that Greece could default and that Italy and Spain would come under further selling pressure. "The biggest concern now is Italy and whether it is at a point where it needs assistance. The fear is that Italy may be too big to bail out. I think that's going to continue spooking markets in the short term," said Justin Gallagher, RBS head of domestic sales and execution in Sydney. The benchmark S&P/ASX 200 closed down 1.9% at 4501.8 after hitting a nine-day low of 4491.7, on heavy volume. The index was approaching the June trough at 4451.7, having fallen 3.4% so far this week. Overnight, Wall Street's S&P 500 fell 1.8% amid steep declines in European equity markets as bond yields of peripheral euro-zone countries soared. In Asian trading, the Shanghai Composite fell 1.5%, Hong Kong fell down 2.1% and S&P 500 futures fell 0.7%. Gallagher of RBS in Sydney said equities were still struggling after Friday's weak U.S. jobs data. He expects markets to stay nervous before China's GDP and U.S. retail sales data Wednesday, as well as the results of European bank stress tests, due later this week. "Price action in every asset class tells me the Australian share market is likely to break the June low of 4451.7," said IG Markets institutional dealer Chris Weston. "The overriding factor here is contagion from Greece, which is spreading to Spain and Italy. We are not getting any clarity from European officials on potential bailouts, so people are taking risk off the table." Risk aversion was most evident in the financial sector, where Macquarie Group fell 6.0% to A$28.22 and National Australia Bank fell 3.7% to A$23.88. Citi reiterated its Sell rating and A$30.50 price target on Macquarie, citing data showing that Macquarie's involvement in equity capital markets and merger-and-acquisition deals has fallen sharply in this financial year. News Corp., which owns Dow Jones Newswires, fell 4.6% to A$15.19 after its U.S.-listed shares fell 7.1% on the U.K. phone tapping scandal. Macqurie cut News Corp. to Underperform and a group of shareholders, led by Amalgamated Bank, along with several municipal and union pension funds, filed claims in a U.S. court, accusing News Corp. of corporate governance failures. Virgin Blue fell 8.8% to A$0.31 and Qantas fell 4.9% to A$1.84 amid further selling after the Federal Government's carbon tax plans announced Sunday, which will see both airlines hit with an additional tax burden when the scheme is introduced. Resources also suffered from global risk aversion, with BHP down 1.9%, Rio Tinto down 2.1% and Iluka down 5.8%. Macarthur Coal rose 37% to A$15.14 after Peabody and Arcelor Mittal launched an indicative cash bid, pitched at A$15.50 a share, less any final dividend. The Australian coal sector piggybacked off the Macarthur bid, with Gloucester Coal, Whitehaven and New Hope rising. "Renewed takeover interest in Macarthur is certainly helping support the coal sector," BBY senior institutional trader Peter Copeland said. "The value that corporates are prepared to put on companies in the resources space is clearly higher than that of investors in the secondary market."
