Just a thought, based on what I have leared:

If you factor in various scenarios before you throw your money at a stock, it will not be "nerve racking" if it happens. And if you didn't factor in a potential pull back, drop, tanking or whatever people want to call it, then maybe it is a good thing to happen, to either learn a lesson from or make you move away from this game or these spec stocks, specislly so biotech which does not produce results after a couple of months, like mining exploration does.

In saying all that, if you do however enjoy a SP increase after yoday, it may be good to remember your next few hours in future and still approach your future investments in stocks with what you can afford to lose.

Good luck.
