Hi,
Maybe FOMO ?

More seriously, like Toygg said, I think it's confidence and trust.
In my opinion, FOMO is a more suitable opposite to FUD. FUD induces emotional reactions leading to panic selling while FOMO also has that emotional characteristic which lead to impulse buying.
I am just wishing that the market will rise by next week, looking to cash out for my trip:/
There are possible signs that the market might recover soon, but then again it could be a bull trap!
