If you don't 'need' the money elsewhere, I would hold onto it for the moment. Selling into a frenzy is particularly tempting when your stomach drops after seeing the double figured red loss percentage on your screen.
The profit results caused a sell-off and was especially protracted given the current market.
If you consider the company as a whole, and what the future might bring, you could weather out the storm.
Like a couple of guys said here, the fuel prices are easing up and the company is a strong, well-established one. If the fuel prices keep dropping, coupled with the cost-cutting measures management has taken, you might see things change. It is also unlikely that the big Virgin umbrella would let Virgin Blue get into too much trouble. One thing is, you probably won't see the stock rise in the immediate future, but it probably will within a few months to a year.
If you are willing to hold in the long term, then IMHO that's the way to go. If this is the approach you're going to take, then IMHO, buying the extra to bring your average down isn't a bad move either.
There's a lot of ifs and maybes there, and it's all IMHO :) Good luck!
