Apparently the Gov shutdown is having no effect on IMGN, it's performing well here. This leads me to believe something positive is known by institutions since info always leaks in biotech. Or, maybe investors are finally waking up to the low risk and high potential return of IMGN relative to their peer group.
The past few days have demonstrated some real strength. I was surprised as well at how far IMGN fell today. It looks to me that we've found a good floor at the 16.90 area and i picked up some more shares at 16.77.
