S&P 500 Snapshot: Down -1.94% for the Day and -3.79% for the Week

Expectations of a Santa Rally went further on hold this week. Our benchmark S&P 500 plunged at the open, triggered to some extent by a savage selloff in oil (WTIC is down -14.5% month-to-date). The 500 proceeded to slide deeper into the red, hitting its -2.13% intraday low early in the final hour. The index closed with a -1.94% Friday loss, and a weekly loss of -3.79%.

The yield on the 10-year note dropped to 2.13%, down 15 bps from last Friday's close.
