"No one is right all the time." No one is saying anything different. I am just saying that all things being equal, who would you trust to make the right investment decision. The professsionals at Marathon Capital or someone posting 24/7 on a message board dedicated to a stock they claim to neither own or short.
For that matter, take a gander at Marathon's other holdings. Some say that NNLX is its only pink sheet and I don't know if that is true or not. Check it out if you care. Looking at the list, though, it doesn't seem thatn Marathon is in the habit of invesing in high risk stocks. So what does it know that persuaded it to buy into Nano? If I thought that they would tell me I would call them in a heartbeat.
