“The job of a stock analyst is to construct a mosaic out of lots of little bits of brightly colored glass and this is just one of those pieces of the puzzle,” said Mark Husson, a retail analyst with HSBC Securities. “Every analyst ought to be aware at least of what they’re saying. They’ve done their research and it ought to be heard.”
