US stocks fell Wednesday as fresh concerns over Spain's deficits overshadowed some positive US economic news. Euro-zone debt concerns were fuelled as ratings agency Moody's said it was reviewing Spain's Aa1 sovereign credit rating for a possible downgrade, while Ireland's parliament approved the country's own bail-out package from the EU and International Monetary Fund. The US currency jumped against the euro to 75.66 euro cents from 74.74 euro cents on Tuesday and rose against the Japanese currency to 84.25 yen from 83.68 yen. In the US, consumer prices rose 0.1 per cent in November, climbing less than expected and buoying the Federal Reserve's plans for a new round of monetary stimulus. Industrial production also gained in November. The blue-chip Dow Jones Industrial Average fell 19.07 points, or 0.17 per cent, to 11,457.47. The broader S&P 500 dropped 6.36 points, or 0.51 per cent, to 1,235.23. The technology-heavy Nasdaq Composite Index was down 10.5 points, or 0.4 per cent, to close at 2,617.22.
