Maybe it was the webcast or other Exxon news, but we had a nice 20% jump in share price today....

Definitely, it had something to do with. On the other hand, the over all market conditions are so dreadful, that any stock would have a problem to sustain a rally.

I am not concerned with the s/p on the short term. Moreover, I am rather pleased with Exxon's mention of the Hungarian play in their presentation, and that is reassuring for the long term.
