RE:green is goodThat's one metric that can be used to value companies but with technology companies, it's a little different. The value lies in the company's proprietary technology and it's tough to place a dollar figure on this. Like Gupta said, "the future is irresistable". You can see an example of this when looking at Netflix's P/E ratio. They are trading at 206 times earnings. I would say that 30x earnings is extremely cheap given the potential here. These earnings aren't the reason to buy. What's to come is. Do your DD and you will know.
