The S&P is down 15%, back to Jan 2007

It's so annoying that reporters quote daily point drops in the Dow. What I want to know is how far the S&P is off a recent reasonable peak.

As of this AM the answers (by the Yahoo graph) are:

• down 15% from November 2007
• back roughly to Jan 2007

So it's given up about a year's growth. If it keeps falling I'll probably be obliged to start making regular purchases on the way down.

I wish these things would happen before my mutual funds charge me capital gains.
