Target (TGT) - Get Report  shares still have room to run despite their 20% jump Wednesday, according to a bullish note from Citigroup that upgraded the stock to buy from neutral. 

The firm believes that Target is still one of the best plays in the retail sector based on the company's strong second-quarter earnings. 

"Yesterday's 20% move was well-deserved in our view. As painful as it is to upgrade a stock after such a move, we want to catch the next 20%, which we
believe will be achieved as the company continues to prove to the market that it is a winner in this retail landscape," said analyst Paul Lejuez.

The firm believes that Target's numerous investments in its digital reach and other upgrades are finally starting to pay off after they "once seemed never-ending."
