IkeEsq., Bingo! Once an exhaustive due diligence is done or absorbed from very astute contributors, the rest should rest on "common sense." It's that simple. I don't know what else would provide peace of mind besides the feeling that you've covered all the bases. I don't know, unless people are going through pressure on their capital, and or other life issues that could serve as false proxies for losing one's clarity. But, it may suffice to suggest exploring some meditation and other techniques, and looking at the stock less often.
The company couldn't go another year even if it wanted to. It's reached it's natural progression end point. The only major stressor I can think of is NOT BEING IN THE STOCK!
