“It’s minimal,” said Savita Subramanian, head of United States equity and quantitative strategy at Bank of America Merrill Lynch. Over all, the sequester could reduce earnings at the biggest companies by just over 1 percent, she said, adding, “the market wants more austerity.”

As a percentage of national income, corporate profits stood at 14.2 percent in the third quarter of 2012, the largest share at any time since 1950, while the portion of income that went to employees was 61.7 percent, near its lowest point since 1966. In recent years, the shift has accelerated during the slow recovery that followed the financial crisis and ensuing recession of 2008 and 2009, said Dean Maki, chief United States economist at Barclays.

Corporate earnings have risen at an annualized rate of 20.1 percent since the end of 2008, he said, but disposable income inched ahead by 1.4 percent annually over the same period, after adjusting for inflation.

“There hasn’t been a period in the last 50 years where these trends have been so pronounced,” Mr. Maki said.

At the individual corporate level, though, the budget sequestration could result in large job cuts as companies move to protect their bottom lines, said Louis R. Chenevert, the chief executive of United Technologies. Depending on how long the budget tightening lasts, the job cuts at his company could total anywhere from several hundred to several thousand, he said.

“If I don’t have the business, at some point you’ve got to adjust the work force,” he said. “You always try to find solutions, but you get to a point where it’s inevitable.”

The path charted by United Technologies, an industrial giant based in Hartford that is one of 30 companies in the Dow, underscores why corporate profits and share prices continue to rise in a lackluster economy and a stagnant job market. Simply put, United Technologies does not need as many workers as it once did to churn out higher sales and profits.
