Am very suspicious of the buying pattern over the last week on the NAS.
Why would you buy volumes at a higher price late in the afternoon when you could have bought for less in a piecemeal way earlier in the day unless you wanted the price to rise? And further, why would you want the price to rise and pay overs if you didn't have a strategy, maybe more stock needed to lend out to shorts or to short yourself, to push it back down later.
Motto: trust no-one in the stock market, especially JP Morgan. To those big boys we are just pawns at the bottom of the sea adrift on the tide of their squillions. Buyer beware!
