The stock market indices started the week with a bang and a nice gap up, ran hard in the morning and reached the session high at about 11:00 am right at key overhead resistance on the S&P 500 near the 1105 area. The Nasdaq 100 at that point reached near 1880, getting up to 1877, but they were unable to make any further advances.

Initially, the pullback came in the general orderly manner, but when no rally materialized in the early afternoon they then rolled over in a 5-wave decline, closing near the session lows going away, filling the opening gaps and falling into negative territory.

Net on the day, the Dow was down 20.18 at 10,190.89, the S&P 500 down 1.97 at 1089.63, and the Nasdaq 100 down 1.67 at 1845.48. Those were way below the earlier levels. The NDX, for example, was 31 points higher earlier in the day, the SPX 16 points higher, and the Dow 140 points higher, so definitely a big give-up late in the session.

The technicals still maintained a positive edge, but just slightly so. Advance/declines on the New York Stock Exchange were about 19 to 12 positive, but on Nasdaq they were about 15 to 11 1/2 positive. Up/down volume was about 6 to 5 positive on New York and almost dead-even flat on Nasdaq. Total volume on New York was light at under 1.1 billion, and Nasdaq traded 1.8 billion.

TheTechTrader.com board, as a result, was mixed but mostly higher, even though most stocks on our board were fractionally higher and off their session highs. The leader by far was InfoLogix, Inc. (IFLG), which we traded earlier in the day at around 4.25, and which ran up to 7.28, closing at 6.90 up 3.29, a gain of 91% today.

Other point-plus gainers included American International Group, Inc. (AIG), which jumped from 35.22 to 38.55, closing at 37.09 up 2.01, and Cree Inc. (CREE) up 1.97 at 66.25.

Fractional gainers of note were Ariba (ARBA) up 42 cents at 50.99, and China Agritech Inc. (CAGC) up 71 cents at 12.77, reaching as high as 13.34 earlier in the session. We exited it from our model portfolio at 13.25 for a 25% trade.

L&L Energy, Inc. (LLEN) jumped to 10.20 on news of an acquisition and being included in the Russell 3000, but profit-taking whittled its gains to 34 cents at 9.63. More than 1 million shares traded, the biggest volume in more than 6 weeks.

Portfolio position Westport Innovations Inc. (WPRT) was up 94 cents to 18.99.

On the downside Google Inc. (GOOG) lost 5.31 at 483.19, 11 points off its high. Goldman Sachs (GS) was down 2.20 at 133.44, and Transocean Ltd. (RIG) down 2.07 at 44.78.

The ETFs were narrowly mixed today.

Stepping back and reviewing the chart patterns, the indices were up sharply in the morning, reversed late morning, and then had a 5-wave decline. The indices not only filled the gaps but closed at the session lows and near the 3-day rising trend lines, where there’s key support.

We’ll see if there’s any downside follow-through or whether the bulls can stem the tide and bring them back up to test and take out the highs.
