there are just better values out there if a portfolio needs an antiviral company. I had VRTX from $9 to somewhere around $44 in October '06. Wall street machinations could take it down to $12 or so sometime this summer. There is no good support on the chart down to there. (unless some buyers decide to pick a price and defend it...but why would they...if the momentum is going to carry them to the bargain basement)
I feel like the IDIX shares I have been buying all season are comparable to VRTX at 9 three years ago.
