The Dow briefly broke above 11,000 — the first time it's been above that level since September 2008 — then settled a few points below that mark.

That wasn't the only benchmark this week: The CBOE volatility index closed at its lowest since October 2007. The 10-year yield crossed 4 percent for the first time, oil topped $87 a barrel and the Thomson Reuters same-store sales index hit a new record in March.

It was the sixth straight up week for stocks, the longest streak since April 2009.
