Wall Street professionals and individual companies often seem to produce "news waves." They flood with pumping (hype), then the bashing (fear), then the pumping, etc. As one of the NYSE specialist recently stated after their profits were below expectations during the markets' recent year long ascent, "What we need is MORE volatility."
It is amazing to watch the stories and predictions that are in the media several days at a time. The same events are ignored until they are pulled out for display during a news wave.
