Tony Zhang says Target (TGT) may be due for a comeback. After shedding 50% of its value over the past year, he says the stock has been trying to form a base which could signal it turning a corner. Tony believes the company offers an attractive valuation compared to peers Walmart (WMT) and Costco (COST) which trade at higher multiples. With TGT trading at 14x forward earnings, Tony sees upside potential to $130 and provides a bullish example options trade idea.
