* Futures: Dow down 49 pts, S&P down 5.25 pts, Nasdaq up 9 pts
March 5 (Reuters) - S&P 500 and Dow Jones Industrials futures pointed to a lower opening for Wall Street on Monday, tracking broad losses on world markets due to worries over Italy and concerns that President Donald Trump has launched a global trade war.
The S&P 500 ended another rocky week on an upbeat note on Friday, but major indexes still posted their worst week of losses since early February after Trump promised tariffs on aluminium and steel and talked bullishly about "winning" a trade war economists say could decimate growth.
World stocks and emerging markets fell for the fifth straight day on Monday, with investors worrying that Italian voters flocking to anti-establishment and far-right groups in record numbers as they delivered a hung parliament.
"Markets' inability to regain confidence is likely to keep stocks defensive," First Standard Financial Chief Market Economist Peter Cardillo said. "(We) face uncertainties over trade wars, and potential political problems facing the Eurozone."
Investors dumped stocks in favour of traditional safe havens including gold and the Japanese yen, with gold touching a near one-week high on Monday.
