It is all up to the whims of the MMs. For the last few weeks, there have been a number of cases when the share price reaches around 35.35, only to be bought down by a few 100s/1000s shares. Really pathetic moves, IMHO, all for some $$ for their masters. Just look at the April option situation, everything will be clear.
An additional reason for them doing could be that they like to feel the power they have on their finger tips.
It is all because I bought this @ 36.42 and the MM and the big traders want me to get frustrated and sell at a loss. Which I have thought about doing at around 35.35. I am missing out on other potential trades having my money tied up in this boring stock.
