posting here keeps him off the streets. It's odd that he would pick such a boring stock as NOV to post about. Why not netflix or telsa motors......I encourage him/her to tell his posting activity to a good therapist.
Such people are either very frustrated with the weak stock performance, or have the illusion that they can manipulate the price with the non-stop nonsense bombardment. They forgot that traders are not stupid and can't be easily fooled. Plus this is not an illiquid stock at all.
relatively illiquid, easily pushed around on low volume. Not by bashers though. the big money guys can certainly manipulate this stock price....most of the time all you need is a say 10 - 15 million $ and you can make a meaningful price change most of the time
