NEW YORK (TheStreet) -- It was a bumpy ride, but stocks managed to close higher on Wednesday, the day before the kickoff of third-quarter earnings season. 

Markets moved erratically, in line with crude oil, which rallied before slumping on an increase in domestic inventories. 

The S&P 500 was up 0.8%, the Dow Jones Industrial Average added 0.73%, and the Nasdaq gained 0.9%.

Alcoa(AA) - Get Report kicks off earnings season on Thursday by reporting results after the 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. International companies that derive a bulk of their sales overseas, for example, will likely take a hit on the currency exchange.

"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."

A smattering of companies have reported before Alcoa. Monsanto (MON) missed quarterly estimates on its top- and bottom-lines and revealed plans to cut as many as 2,600 jobs over the next two years.

Monsanto said lower commodity prices would likely reduce sales through 2016.

Constellation Brands(STZ) - Get Report reported a better-than-expected second quarter, driven by strong growth in its beer brands including Corona and Modelo. Overall beer sales climbed 14% to $1.02 billion, representing 59% of total revenue. Wine and spirit sales increased 3%.

Yum! Brands(YUM) - Get Report plummeted 18.9% after quarterly results showed the company is still suffering from a food safety scandal in its critical Chinese market. Quarterly earnings of $1 a share missed estimates by 7 cents.

Crude oil lost gains of more than 2% after crude inventories rose by 3.1 million barrels in the past week, according to the Energy Information Administration.
