Nice to see someone post here other than a spammer. This is probably one of the deadest boards you can find. Also one of the better stock performers. I bot in almost a year ago as a value play and have been rewarded very well. Stock is held almost exclusively by institutions - by the volume of msgs very little retail.
I'm not sure if there is any reason for the fluctuations - but they can be played. Have bot around 42 and sold at 50+ several times the past 2 mos. Didn't buy in this past week because the sharp drops were unusual.
Fundamentals are great and company appears to be very well run. Do your DD and see what you think. Good luck
