Despite trading off with the market last week, Cognizant Technologies (NASDAQ: CTSH) remains attractive to nearly every sell-side analyst on the street.

Cognizant reports earnings before the bell tomorrow. As I said, almost every sell-side analyst covering the stock remains bullish on the stock going into numbers for a variety of reasons, including the potential for an upside surprise in revenues and any mildly bad news potential from the quarter probably priced into the stock.

Operating performance is expected to remain strong according to my research. Christine Penzino of JP Morgan reported that her channel checks indicate the potential for revenue upside this quarter due to "driven by strong demand for offshore ITS." This shouldn't come as a surprise to investors who follow this industry closely because strong demand in the offshore ITS space was recently displayed in Syntel's (NASDAQ: SYNT) quarter. However, I think margins could come in low as a result of mostly seasonal headwinds such as wage hikes and increases in visa costs.
