For what it's worth, on the day that it was announced that Icahn purchased a stake in JetBlue, the carrier's stock price was $6.07, though a day later it climbed all the way up to $7.38. Meanwhile yesterday, when it was revealed that Icahn had sold so many shares in the airline, the stock closed at $6.09. So JetBlue's stock is basically at the same level as it was pre-Icahn. Icahn has already cut his JetBlue stake in half
