Looking forward to Thursday, Jim Cramer plans to monitor corporate earnings reports from several companies.
Union Pacific, for example, is expected to report earnings before Thursday's open.
From its assessment of the coal industry, crops or intermodal freight, Cramer said there are many reasons to listen to this railroad's conference call.
Cramer noted Union Pacific has re-priced many of its contracts lately, too, which should improve margins. To Cramer, this stock might be worth buying on a pullback ahead of the quarter.
