[BRIEFING.COM] The stock market's early advance has rolled over, leaving the three major indices to return to negative territory. The drop, however, has only offset a small portion of the previous session's heady gain and stocks are still trending toward a week-to-date gain in excess of 2%.

Financials continue to be a drag; the sector is now down 1.1%. AIG (AIG 35.48, -3.80) is a primary laggard in the sector. Shares of the insurer have been shunned for the entire session, despite better-than-expected earnings for its latest quarter. AIG's weakness has spread to its peers and dragged multiline insurers, as a group, to a 2.8% loss.

Of the 10 major sectors, only consumer discretionary stocks (+0.1%) and materials stocks (+0.5%) are sporting gains.
