NEW YORK (TheStreet) -- Shares of Burlington Stores (BURL) - Get Report are higher by 2.5% to $51.20 in pre-market trading on Thursday morning, following a rating upgrade to "buy" from "neutral" at Goldman Sachs.

The upgrade comes as the firm believes Burlington can get past the unusually warm winter weather and continue to expand its margins in the upcoming quarters.

Goldman believes the company's long-term productivity and margin story are intact and underappreciated, The Fly reports.

The firm upped its price target to $59 from $56 on Burlington stock.

Burlington Stores is a Florence, NJ-based retailer of branded apparel. The company has more than 500 stores in 44 states and Puerto Rico.

The company offers a variety of apparel options including cloths for winter, women's apparel, children's wear, swimwear, sleepwear and more. Customers can also find jewelry as well as beauty and fragrance products.

Separately, TheStreet Ratings has a "sell" rating and score of D on Burlington Stores stock. This is driven by a number of negative factors, which TheStreet Ratings believes should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks it covers.

Among the areas TheStreet Ratings feels are negative, one of the most important has been a decline in the stock price during the past year.

TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
