Stock price when the opinion was issued
Yesterday, they reported a surprisingly strong quarter with in-line sales, an earnings beat, but share flatlined today. Why? UAL offered 2 sets of guidance--one for a stable economy and the other for a recession. That's a brilliant idea. Bookings could be stable or weaken. Both forecasts are certainly possible.
Shares have rallied since last fall, so take profits. But remember that all airlines are trades.
