Energy, banks weigh on S&P, Dow; biotech boosts Nasdaq

The S&P 500 and Dow stock indexes were weighed down by falling energy shares as oil prices fell on Wednesday and added to investor concerns about low inflation, while healthcare and technology stocks helped lift the Nasdaq Composite index. Energy was the weakest S&P sector with a 1.6% decline after oil prices reversed course during the morning session and US crude touched its lowest point since August despite larger-than-expected declines in inventories.

NEW YORK — The S&P 500 and Dow stock indices were weighed down by falling energy shares as oil prices fell on Wednesday and added to investor concerns about low inflation, while health care and technology stocks helped lift the Nasdaq Composite index.

Energy was the weakest S&P sector with a 1.60% decline after oil prices reversed course during the morning session and US crude touched its lowest point since August despite larger-thanexpected declines in inventories.

Continued weakness in oil futures added to investor worries about inflation and as a result hurt cyclicals such as banks and industrials, according to Chris Zaccarelli, chief investment officer at Cornerstone Financial Partners in Huntersville, North Carolina.

“Because people are seeing oil lower as another harbinger of lower inflation, a lot of other cyclicals ( besides energy stocks) aren’t doing well,” Mr. Zaccarelli said.

Bank stocks fell 0.80% as investors worried interest rate margins would be hurt by a flattening yield curve, which is also driven by inflation expectations.

Industrial stocks were also among the biggest decliners with a 0.70% drop. Caterpillar’s 3.30% fall weighed on the sector while a 1.60% rise in FedEx was its biggest boost.

Investors looking for growth opportunities turned to Nasdaq, which contains many technology and biotechnology companies, according to Zaccarelli.

Health care stocks were helped by reports that US President Donald J. Trump’s efforts to rein in drug prices may be friendlier than expected to the industry, according to Brad McMillan, chief investment off icer for Commonwealth Financial in Waltham, Mass.

In general equity investors are biding their time ahead of quarterly results, which are expected to be good.

“We’re just continuing to bounce around here until second quarter earnings come out,” said Mr. McMillan.

The Dow Jones Industrial Average fell 57.11 points, or 0.27%, to close at 21,410.03; the S&P 500 lost 1.42 points, or 0.06%, dropping to 2,435.61 and the Nasdaq Composite added 45.92 points, or 0.74%, rising to 6,233.95.

The energy index has fallen 14.90% so far this year compared with an 8.90% rise for the S&P 500. Oil futures have fallen about 21% so far this year.

The four- company telecommunications sector was the second weakest with a 1.20% drop, with AT&T, Inc. leading the percentage declines.

The Nasdaq biotechnology index was up 4.10%, on track for its biggest one-day gain since the day after Trump’s Nov. 8 election. Its biggest boosts were Celgene, and Regeneron which both rose more than 5% and Biogen, which rose 4.70%.

Declining issues outnumbered advancing ones on the NYSE by 1.70-to-1; on Nasdaq, a 1.04-to-1 ratio favored decliners. About 7.16 billion shares changed hands on US exchanges compared with a 6.92 billion average for the last 20 sessions. —
