Danhoff,
You state the following:
"So, since we have moved from the low 40s to 34 (about a 20% drop) on 'no news'. Does this tell us the 'CCU TA' shows some unpalatable announcment is around the corner?"
Unfortunately that has been the pattern Danhoff, you are quite correct to suspect what you have stated.
No news has more times than not equated to, "oh no" sometime later.
Let us all admit that.
