New York - US stocks spent another session in a tight range on Wednesday, with the S&P 500 ending a few points higher and extending a rally that seems to be happening in slow motion.
The benchmark S&P 500 index finished just a hair away from its highest close in three months, but with earnings season winding down and many traders away, volume was light.
For the next couple of days the greatest influence may be the options market, which is seeing heavy volume in August call and put options clustered around the 1,400 level for the S&P 500.
If the index closes at or very close to 1,400, those options expire worthless on Friday. That means market-makers have an incentive to try to make that happen, or "pin" the index at 1,400.
The S&P 500 was up seven of the past nine sessions but the volume has been extremely light due to summer holidays and a lack of news from Europe. On Wednesday, about 4.79 billion shares traded on the New York Stock Exchange, the American Stock Exchange and Nasdaq, well below last year's daily average of 7.84 billion.
"I think we are facing technical resistance at 1,405 (on the S&P 500), which is the level of closing highs in early May. We haven't been at that level since, and until we have a catalyst to move significantly above this, the market is likely to consolidate," said Randy Frederick, managing director of active trading & derivatives at Charles Schwab.
The S&P 500 rallied early in August and reached highs not seen since early May in anticipation that central banks in the United States and the eurozone will take action to stimulate their respective economies in September.
Shares of Deere & Co lost 6.3% to $75.10 after the world's largest agricultural equipment maker reported a lower-than-expected quarterly profit on Wednesday, citing weak sales in China, India and other emerging markets. Rival Caterpillar slipped 0.3% to $87.61 as the biggest drag on the Dow.
Staples slumped 14.6% to $11.49 as the worst performer on the index after the office supply chain reported lower-than-expected quarterly revenue on weak demand in North America, Europe and Australia, and forecast flat sales for the fiscal year.
