While not wanting to dive into the detail of this particular post, it is probably a useful juncture at which to bring this information to the thread.It is fair to note that there is no direct linkage between the circumstances of the stock referred to and QBL. I am not drawing one either.
However, it does serve, in my opinion as a timely reminder around how a blinkered or narrowly focused approach to stock selection may well impair one's better judgement.
This was posted by @NineLives in 2014 on the aforementioned TON forum. Whatever your perspective on QBL, this post is worth reading, in my view.
