You are probably correct since I have not followed CCMP that long, but as I understand it, they make slurries for use in the CMP process for copper chips, while LRCX makes the CMP equipment. The growth rate of the slurry end of the market is slowing as the sector itself slows, and my understanding is that the growth rate is now down in the low teens, which makes it hard to justify the current PE ratio.
Like I say, that is my understanding and I could well be wrong.
