Discount chains Ross, T.J. Maxx, and Burlington are planning to add more than 300 new stores. Here's why major retailers should be nervous about their growing off-price rivals.

• Off-price chains are likely to get a boost in the months ahead as shoppers seek low prices. 
• Ross Stores is planning to open 100 new locations this year, while T.J. Maxx plans 150 openings, and Burlington as many as 80.   
• Burlington is poised to be the standout, Morgan Stanley analysts say. The retailer reported strong fourth-quarter earnings and is making strides on its revamp strategy.

While several retailers have been cautious about the months ahead, a bright spot is emerging in at least one part of the market. 

2023 is looking like a strong year for off-price chains like Burlington Stores, Ross Stores and T.J. Maxx, as shoppers look to save money where they can.
