Mobile semiconductor company Qualcomm was upgraded by Susquehanna Financial analyst Chris Caso, who suggested the worst for the company and the stock may be over. Caso raised his rating to positive, after being at neutral for the last 18 months. He boosted his stock price target to $60, which is 29% above Tuesday's closing price of $46.52, from $53. Caso said he is no longer too concerned about Qualcomm's China business and pressure on royalties. "The China issues are now mostly resolved, and the fact that [Qualcomm] has proven that they can collect royalties in China makes us incrementally more confident that they can continue to collect globally,". Stock located in leading diagonal triangle, looks oversold, suppose they can bounce until $50 per share
