JPMorgan upgraded JetBlue (JBLU) to Neutral from Underweight with a $7 price target. The company is increasingly well-positioned for a modest potential move to the upside based on improving market sentiment, and its upcoming Q2 guide coming next week may exceed consensus, the analyst tells investors in a research note. JetBlue is the second least-liked airline based on sell-side ratings, after Spirit (SAVE), with short interest on the stock also remaining "stubbornly high", the firm added.
