$United Continental(UAL)$ There is this old saying that you can trade airline stocks but shouldn't invest in them. Meaning: They can swing widely in a very short period for unforeseeable reasons. If you somehow can anticipate the swings, investing in airline stocks can be very profitable. If you look at the performance over many years compared to the overall market, however, they tend to perform badly. If you take into account the high risks deriving from geopolitics, economic cycles, plane crashes etc, it really doesn't seem to be wise to invest in them.

Personally, I am planning to ride the wave for couple more weeks and then divest, wait until it drops again and buy again (Market Timing - I know, it never works out as planned).

I can tell you one thing: it is very stressful to invest in airline stocks.
