Oct 20 (Reuters) - The Dow briefly touched a record high and the S&P 500 traded close to its peak on Wednesday as investors eyed better than expected third-quarter earnings from U.S. companies. While the Nasdaq lagged as technology stocks took a breather, the S&P"s utility sector was gaining sharply and the healthcare index rallied for a second day in a row after strong forecasts from Anthem and Abbott (ABT.N). The Dow Jones Industrials Average (.DJI) briefly surpassed its previous record reached in mid-August, while the benchmark S&P 500 index (.SPX) at one point came within roughly five points of its early September record. The S&P had fallen almost 6% below its record by Oct. 4 as investors worried about supply chain problems, profit margin pressures, higher wages and increasing input costs ahead of the earnings season, which kicked off last week. And while U.S. companies were citing supply chain problems and higher costs during their earnings calls investors have been relieved so far that they seem to be able to maintain profit margins by passing on costs to customers, according to Jack Janasiewicz, strategist and portfolio manager at Natixis Investment Managers Solutions. "Earnings are what matter and thus far what we"ve seen have actually been better than expected. Margins are actually holding up, said Janasiewicz. "The bar was set pretty low coming into (earnings season) so that makes things a little easier ... Things are coming out, so far, better than expected. That"s putting upward pressure on stocks." With just about 14% of S&P 500 third-quarter reports in, analysts were expecting earnings for the benchmark index to rise 33% from the year-ago quarter. More than 85% of those who reported beat expectations, according to the latest data from Refinitiv.By 2:49PM ET, the Dow Jones Industrial Average (.DJI) rose 148.19 points, or 0.42%, to 35,605.5, the S&P 500 (.SPX) gained 15.13 points, or 0.33%, to 4,534.76 and the Nasdaq Composite (.IXIC) dropped 13.52 points, or 0.09%, to 15,115.57. Eight of the eleven major S&P 500 sector indexes were trading higher, led by healthcare stocks (.SPXHC),up 1.6%, and utilities (.SPLRCU), up 1.5%, while technology shares (.SPLRCT) were down 0.3% after rallying for the previous five sessions.
