NEW YORK, RAW – US stocks have finished lower, extending losses late as investors grew more jittery in the run up to third-quarter earnings, while a jump in Tesla shares helped support the market.

Adding to investor caution, the Federal Reserve is expected to release minutes on Wednesday from its last policy meeting, which market participants will scour for hints about when the US central bank could begin tapering its massive bond-buying program.

All three major US stock indexes ended in the red with the Dow down the most, weighed by healthcare and industrials.

Earnings unofficially kick off this week with results from JPMorgan on Wednesday and other banks to follow. JPMorgan’s shares shed 0.8 per cent on the day, while the S&P 500 banks index edged down 0.6 per cent

Analysts expect to see strong US profit growth for the third quarter, but investors are worried how supply-chain problems and higher prices will affect corporate America as businesses emerge from the coronavirus pandemic.

A number of companies have warned of issues heading into the reporting period.

“For the most part, institutional portfolio managers are of the view, ‘Let’s see what earnings look like and how much of a negative impact is being seen from shortages, higher rates and supply-chain bottlenecks’,” said Michael James, managing director of equity trading at Wedbush Securities in Los Angeles.

“A lot of those factors are currently reflected where equity prices are now.”

The Dow Jones Industrial Average fell 117.72 points, or 0.34 per cent, to 34,378.34; the S&P 500 lost 10.54 points, or 0.24 per cent, to 4,350.65; and the Nasdaq Composite dropped 20.28 points, or 0.14 per cent, to 14,465.93.

Six of the 11 major sectors of the S&P 500 ended the session in the red, with communications services suffering the steepest percentage loss.

Tesla advanced 1.7 per cent after data showed the electric vehicle maker sold 56,006 China-made vehicles in September, the highest since it started production in Shanghai about two years ago.

The company’s shares provided the biggest boost to the S&P 500 and the Nasdaq.

Shares of American Airlines Group rose 0.8 per cent after the company estimated a smaller-than-expected adjusted loss for the third quarter and signalled improved bookings for the rest of the year.

MGM Resorts surged 9.6 per cent after Credit Suisse upgraded the stock to ‘outperform’ from ‘neutral.’

Nike gained 2.0 per cent after Goldman Sachs initiated coverage with a ‘buy’ recommendation.

Investors also weighed comments from Fed Vice Chair Richard Clarida, who said the central bank has all but met its employment goal for reducing its bond buying program.

US data showed the labour market remained tight, with a record number of Americans quitting their jobs and job vacancies numbering more than 10 million, stoking inflation fears as employers hike wages to attract and retain workers.

Wednesday’s consumer price index report will attract attention from investors seeking clues about inflation.

Advancing issues outnumbered declining ones on the NYSE by a 1.38-to-1 ratio; on Nasdaq, a 1.42-to-1 ratio favoured advancers.

The S&P 500 posted 10 new 52-week highs and 10 new lows; the Nasdaq Composite recorded 46 new highs and 94 new lows.
