Their printer business is dying (nobody prints things anymore). They do have an active server business.

Do I think they will be around if 5 years, yes. Do I think they will be significantly more valuable, probably not. Do I think their stock will go up in the next 6 months, yes... I just added it to my watch list and will buy a few shares on their next down day.

Practice on a stock simulator... it will save you a shit ton of money. Most new investors think it is all easy, you pick a stock and you make money... Most likely though you will pick a stock and lose money. Play for a while before you commit yourself.

I just took a look at PANW... They have been losing money forever though their revenue has been growing. I'm surprised that they have lasted this long without getting hammered.

One of my previous employers had been bought out. The management team had been replaced by a team that had the notion of increasing revenue at any cost. That gets really expensive after a while. It would appear that PANW might have a little of that going on. Their revenue is increasing year over year while their annual loss is steady. Meanwhile their executive team has a very handsome salary package for a company that has never made a profit.
