Equities end roller-coaster day lower

Equity indexes were lower at the end of the day after vacillating between positive and negative. The CBOE Volatility Index was up fractionally.

The S&P 500 was down 6.77 points to close at 1756.54, just about matching the morning low. It had climbed into positive territory and hit 1768 before sliding into the close. It has support at 1730.

The Nasdaq 100 gave up 7.65 points to finish at 3377.73, following a pattern similar to that of the SPX. It has support at 3300.

The Russell 2000 was down 5.35 points to 1100.15. The small-cap index has support at 1087.

(When equity indexes are at highs, further resistance levels are obviously projections not based on previous trading patterns. We therefore will refrain from listing any.)

The VIX was up 0.10 points to 13.75. The volatility index traded as low as 13.28 going into the final 90 minutes of the session.

The VIX futures were mixed, with the November contracts off 0.05 points to 14.50 and the December futures flat at 15.55. That had the iPath S&P 500 VIX Short-Term Futures Note (:VXX) down fractionally to $12.92.
