Hard to believe these stocks will keep going like this.
I first started watching POT when it was doubled on the year and pulled back to under $100. Lots of the talk on yahoo was trashing the company (I think around Sep 2007) so I chickened out. Having since followed it and the segment, I think that any pull back on these wild swings are a buying op. I wish I would have bought.....solars too seem to act like this but more speculative.
The way you make money in the stock market is to buy the stocks that go up. Seems pretty simple. I bought some MOS a few days ago, and it has been a great investment.
