The goal line for the consensus crowd is the 50 day moving average (see chart). I don't use the 50 day to make capital decisions, but it's important to watch behavior around that line. It’s kind of like watching pigeons flock to bread crumbs.
The XLF was down -6.3% today, going out at 21.07. If this US Financials index breaks my support line at 20.58, and closes there, I see 23-24% of expeditious downside.
