Daniel P. Collins, editor in chief at Modern Trader Magazine discusses different variables in the polls on the Brexit vote.

The point is this: we’ve had an intense start to this rebound very similar to what you’d get in a Christmas rally. But think back to all those rallies with a time limit of 3-4 weeks.

The S&P 500 sank 1.5 percent to 1,935.09 at 4 p.m. in New York, the lowest level since Aug. 12. Today’s slide was the biggest in almost three weeks. Selling accelerated in afternoon trading as index futures contracts expiring in December slipped below 1,940, a level where two previous declines had ended earlier today.

U.S. stocks rose during one of the slowest trading days of the year as Internet and small-cap shares extended a rebound from losses last week.

U.S. stocks fell, sending the Russell 2000 Index down more than 10 percent from its March high.

It seems that in spite of the Monday rally, some bearish option traders are reluctant to throw in the towel just yet.

The Russell 200 has been leading to the downside; The Nasdaq still repelled by the trend line; Dow may or may not be tracing out an ending diagonal wedge.

CBOE Holdings Inc. and NYSE Euronext will share the right to list options on equity indexes owned by Russell Investments.
