The Motley Fool on Blue Nile again

Blue Nile had a good trading day yesterday. It’s always interesting to me to hear analysis of why a stock is up or down on a particular day. After earnings or big news you can understand. But in the middle of nothing? A big player bought, stock goes up, a big player sold, stock goes down. Very simple. Discuss long term trends, not a one day movement. Weird that people can listen to this type of analysis obsessively day in day out. Rant over.
