I have been watching IRI for two years.
I bought a little in the Feb correction.
The SP went back up towards $4 , but surprisingly not as convincing as I expected.
Somebody knew. All the posters were very happy with the stability and easrnings.

2. Long history of high EPS growth
3. No management change
4. No mention of contract loss to a competitor
5. It may be a TIMING issue, the fall in EPS
