NEW YORK (TheStreet) -- Stocks were slightly lower on Thursday as markets pulled back from Wednesday's modest gains ahead of the kickoff of earnings season.

Alcoa (AA) - Get Report unofficially kicks off earnings season on Thursday with third-quarter results after the closing bell. Expectations for corporate earnings are already low. Third-quarter earnings are expected to decline 4.2% from a year earlier, according to Thomson Reuters. Similar issues that plagued the second quarter such as a stronger U.S. dollar and lower energy prices are expected to carry over into this past quarter.

"We've seen companies set the bar rather low again for earnings season which has been typical," Chris Gaffney, president of EverBank World Markets, told TheStreet. "What we are looking for is to see what impact the stronger dollar has on U.S. companies. We are expecting and have seen some warnings from some of the multinationals that this strong dollar is hurting sales."

Jobless claims in the U.S. fell to their lowest level since mid-July, according to the Labor Department. The number of new claims for unemployment benefits fell 13,000 to 263,000 in the week ended Oct. 3. The less-volatile four-week claims average fell 3,000 to 267,500.

"While jobless claims are just one dimension of labor market activity, the trend in the series is encouraging and suggests the slowing in the September employment report may prove to be temporary," wrote Kevin Cummins, senior U.S. economist at RBS Securities, in a note.
