It was a huge session for the indices, starting out with a bang on a gap up. They did pullback pretty quickly in the morning, but held support immediately, and the rest of the day was up and away, as the indices soared to new multi-year and all-time highs in some cases.

The Dow closed just 10 points under 13,100, up 136. The S&P 500 was up 15, and the NDX up 22 Ã,½. The Philadelphia Semiconductor Index (SOXX) was up 3.82.

The technicals were solidly higher by 23 to 9 on advance-declines on New York, although Nasdaq was only 3 to 2 ahead. Up/down volume was 4 Ã,½ to 1 positive on New York with total volume of 1 2/3 billion traded. Nasdaq traded a whopping 2 2/3 billion today with about a 5 to 3 positive ratio.

TheTechTrader.com board was mostly higher, led by far by DXP Enterprises (DXPE), a recent Chart of the Week, which exploded after an earnings report and closed up 6.79 today.

Junior biotech BioDelivery Sciences (BDSI) jumped 1.41 today on 14 million shares, although that was way off the earlier high when it was up more than 3 Ã,½ points. JA Solar (JASO) was up 1.41 on 2.8 million. Solar Fun Power (SOLF) was up 78 cents

Other gainers of note, a couple recent Charts of the Week were strong. aQuantive (AQNT) gained 33 cents and JDA Software (JDAS)was up 31 cents. Chindex (CHDX) gained 59 cents. ISIS Pharmaceuticals (ISIS) snapped back 33 cents. SunOpta (STKL), another recent Chart of the Week, tagged a new all-time high today and was up 35 cents.

On the downside, Sigma Designs (SIGM), after its earnings report, dropped 82 cents. Force Protection (FRPT), which we sold yesterday, dropped 1.01. Ascent Solar (ASTI) gave back 53 cents.

Stepping back and reviewing the hourly chart patterns, the indices surged higher and moved solidly above their moving averages and may even be a tad overbought here. Late in the session the indices did back and fill a little bit, and we’ll see if that’s the beginning of topping action or just consolidation before more progress is made.

But right now the upside steamroller is still in effect, and accelerating to the upside.
