Lisa Shalett, the chief investment officer of Merrill Lynch, says the recent upward tragectory in the markets is due to a mixture of "surprise" and "relief." Surprise at the resilience of the U.S. economy, and relief that Europe is looking is no longer on the brink of collapse. Many market watchers have been touting equities during this run up, and Shalett is no exception. The Pulse slowed today on news that fewer Americans are quitting their jobs. It turns out “churn," is actually a sign of a healthy job market.
