US stocks fell yesterday after a key index of business activity in the American Midwest region showed a surprising contraction, but buying of technology bellwethers like <strong>Cisco Systems</strong> at the end of a strong quarter limited losses.<br /><br />The top drags on the session were some of the quarter’s best performers including industrials, materials and banks.<br /><br />The Institute for Supply Management-Chicago’s business barometer unexpectedly fell to 46.1 in September, a level that indicates contraction in the regional economy.<br /><br />Typical of quarter-end action, trading was choppy and volume light.<br /><br />The Dow Jones industrial average slipped 29.92 points, or 0.31 per cent, to 9,712.28.
