No worries and certainly not a "cop out" answer - heck, if we were all 100% certain about a stock going ballistic, we wouldn't be sitting here posting on a message board. We'd be chillin' on our own island somewhere drinkin' a fruity umbrella drink (ok, so Gofor is already doing that, but the rest of us can dream!)...
I think you're right - figure out what my dollar figure is that I'm comfortable to invest, fire about 75% of that at my initial position and hold some "reserve" funds to average down if the opportunity should present itself.
We'll see how things shake out Monday. Think I might try to contact management myself and get a "feel" for the company before I pull the trigger...but from everything I've seen, the gun is definitely loaded.
All the best. Here's to a good day for all of our plays tomorrow!
