Caveat: I don't know anything about individual stocks but I am trying to learn about charts.
I was curious so I did some plotting on Yahoo. Looks like PKD has had a downturn since its 50 day SMA crossed above its 200 day. Don't know what's up with that. Could either be a good time to buy or a warning that things may be getting worse. Looks a little scary to me.

ISIS - looks like good trends as far as moving averages though the price is a bit far above the 20 day average. You might look for a better time to "buy in" (but you know how that goes, if it keeps going up, there may never be a good time, LOL.)

If I'm going to do some serious investing - along with trying to look at everything else, I always buy a copy of IBD (Investors Business Daily) and check their rating there. If it doesn't have an "A rating" of some kind, I stay clear. May be a bit conservative for some investors, just my two cents.
Good luck!
Disclaimer: I have no financial association with IBD except as a customer when I buy a copy now and then.
