Wall Street weakened overnight as investors awaited more details from US Federal Reserve policy makers on paring back their bond buying at a two-day meeting starting tomorrow.
In late afternoon trading in New York, the Dow Jones Industrial Average fell 0.15 per cent, as declines in shares of Bank of America, last 1.3 per cent weaker, and Chevron, last 1 per cent lower, weighed on the index. The Standard & Poor's 500 Index shed 0.24 per cent, while the Nasdaq Composite Index dropped 0.18 per cent.
US Treasuries also declined, pushing yields on the 10-year bond 4 basis points higher to 2.60 per cent.
"There's a concern that whatever the FOMC says or does will lead to a dramatic reaction in the market, much like we saw in June," Stephen Massocca, managing director at Wedbush Equity Management in San Francisco, told Reuters.
Investors are also eyeing further guidance from the European Central Bank and the Bank of England as their officials are set to meet as well in the coming days.
