Wall St ends near flat amid wait for more US jobs data

The S&P 500 have ended little changed, with technology shares gaining but investors nervous about Middle East tensions and more US labour data due this week. Nvidia shares rose 1.6 per cent, helping to lift the S&P 500 technology index. However, Tesla shares fell 3.5 per cent after the electric car maker reported third-quarter vehicle deliveries below estimates. Investors monitored Middle East news after Israel and the US vowed to strike back following Iran's attack on Israel on Tuesday. US President Joe Biden said on Wednesday he would not support any Israeli strike on Iran's nuclear sites in response to its missile attack and urged Israel to act "proportionally". Data released early on Wednesday showed US private payrolls increased more than expected in September, further evidence that the labour market is not deteriorating. Investors remained focused on September non-farm payrolls data due on Friday while US jobless claims data is due on Thursday. "We have the jobs report Friday, and then earnings season starts at the end of next week," said Michael O'Rourke, chief market strategist at JonesTrading in Stamford, Connecticut. "We're near all-time highs, and we know we have a friendly Fed out there. Before they push stocks to another round of new highs, investors want to hear some positive commentary from companies. People like that the Fed is very dovish and they are just waiting for another reason to push prices higher." The Dow Jones Industrial Average rose 39.55 points, or 0.09 per cent, to 42,196.52, the S&P 500 gained 0.79 points, or 0.01 per cent, at 5,709.54 and the Nasdaq Composite edged up 14.76 points, or 0.08 per cent, to 17,925.12. The market ended September with strong gains after the Federal Reserve kicked off its monetary policy easing cycle with an unusual 50-basis-point rate cut to shore up the jobs market. The S&P 500 is up 19.7 per cent for the year so far. Odds of a quarter-percentage-point rate reduction at the Fed's November meeting are at 65.7 per cent, up from 42.6 per cent a week ago, the CME Group's FedWatch Tool showed. JPMorgan Chase and other big banks will kick off S&P 500 third-quarter earnings season on October 11. A strike by 45,000 dockworkers halting shipments at US east coast and Gulf coast ports entered its second day on Wednesday with no negotiations scheduled between the two sides, sources told Reuters. The dockworkers' strike is costing the economy roughly $US5 billion ($A7.3 billion) per day, JPMorgan analysts estimated. Among declining shares, Nike dropped 6.8 per cent after the athletic footwear and apparel maker withdrew its annual revenue forecast just as a new chief executive is set to take charge. Shares of Humana Inc fell 11.8 per cent after the health insurer said it expected enrollment in its top-rated Medicare Advantage plans for those aged 65 and above to decrease for 2025. Declining issues outnumbered advancers on the NYSE by a 1.18-to-1 ratio; on Nasdaq, a 1.09-to-1 ratio favoured decliners. The S&P 500 posted 27 new 52-week highs and two new lows; the Nasdaq Composite recorded 80 new highs and 133 new lows. Volume on US exchanges was 11.81 billion shares, compared with the 12.05 billion average for the full session over the last 20 trading days.
