(TheStreet.com) JBLU Daily Chart (click to enlarge) Downside and Upside from Support:- As price breaks below the 18.50 support area, it opens up the 2016 lows between 15 and 16. - I think if price indeed approaches this 15-16 area, JBLU would look like an appealing stock at a discount, but with a limited upside due to competition. Still, from the depths of 15, there should be upside of at least 30% (back towards 20) and up to 50% (towards 23).
