I love the volume and the fact it is still up from last week. yes there are many who take a profit and even possible some shares sold. That is what the market is for is to raise capital and the price today helped raise capital at a higher price. Also the volume today clearly shows many more have this on radar and now will watch it closer and that also is good for price moves up.
Chart is looking good to me as it held above the fifty day now.
It takes a great mix of all kinds of traders to make stocks go up.
