It is a tough call. When you see something believed to be seriously undervalued, such as LEO (in my opinion), you load up when you can. At some point, it will run away from everyone and a bunch of people will be wishing they had more.

That said, I have been patient in that I was buying all the way down. I look at this as a long term development project. It isnt where it is today or in 3 months but in a year or two.
