Stock indexes closed lower for the second day in a row as a sharp drop in railroad operator CSX pulled other industrial companies broadly lower and more in Wednesday’s Stock Market Update.

Banks also fell Wednesday as investors worry that lower interest rates will hurt their profits going forward.

The yield on the 10-year Treasury fell to 2.05% from 2.12% late Tuesday as investors headed for less risky holdings. Utilities, which are also considered a safer bet, made late gains and held up well.

Abbott Laboratories gained 3.1% and pushed health care stocks higher after the maker of infant formula and drugs raised its forecast for the year. UnitedHealth Group also rose 0.7%.

Corporate earnings reports are getting into full swing this week, and investors have been mostly cautious in their assessments of them. Earnings are still expected to decline for S&P 500 companies in the second quarter.

CSX plunged 10.2% after saying it now expects its revenue to decline as much as 2% this year, after previously saying it expected growth. Investors read that as trouble for the entire industry and sent the stock of other railroad operators lower. Union Pacific sank 6% and Norfolk Southern dropped 7.4%.

Several large companies are scheduled to report earnings later Wednesday and throughout the remainder of the week. Netflix will release its results late Wednesday, as will IBM. UnitedHealth Group, Phillip Morris and Morgan Stanley are scheduled to release their results Thursday.

The S&P 500 fell 19 points, or 0.7%, to 2,984. The Dow Jones Industrial Average lost 115 points, or 0.4%, to 27,219. The Nasdaq gave up 37, or 0.5%, to 8,185. The Russell 2000 index fell 0.7%.

“You’re getting tempered guidance for the most part,” said Lindsey Bell, investment strategist with CFRA Research. “It’s more of a reality check. Second-half growth is not guaranteed at this point.”

Investors are likely going to pause and take a more cautious approach going forward, she said, as stock values reach record highs. The technology-heavy Nasdaq is up more than 23% for the year and the broad S&P 500 is up more than 19%.

A weak home construction report loomed over companies that build homes. Hovnanian fell 3%, Lennar shed 1.9% and Toll Brothers fell 1.9%.

U.S. home construction slipped last month as an uptick in the building of single-family homes was offset by a big drop in apartment construction. The figure fell short of economists’ forecasts.

Nu Skin Enterprises fell 14.6% after the seller of skin care and nutritional products slashed its profit and revenue forecast for the year. The company and other direct sellers of wellness products are facing increased scrutiny from the Chinese government and that is hampering sales growth. Nu Skin gets 33% of its revenue from China, according to FactSet.
