It was a rather tedious session for most of the day, but the indices did manage to have a strong late afternoon rally that took them to the highs for the day, and they closed there.

The day started out with a back-and-forth movement. We did have an early rally try that failed right at resistance at 1515 on the NDX and 1205 on the S&P.

They came down, retested the lows on the NDX and above them on the S&P, and then rallied back up to the highs and closed right there, with the S&P and Dow closing at the highs for the day going away.

Net on the day the Dow was up 30, the S&P 500 up 6 3/4, and the NDX and Composite both up 9 1/2. The SOX was up about 2.37.

The technicals were flat to slightly higher, with about a 17 to 15 positive ratio on New York and 16 to 14 on Nasdaq. Up/down volume was better than 2 to 1 on New York and about 5 to 3 on Nasdaq.

Total volume was about 1.4 billion on New York and 1 2/3 billion on Nasdaq.

TheTechTrader.com board was very active, and there were some big winners today. BOOM, highlighted as one of our Charts of the Week this weekend, gapped up, pulled back, and then popped late to close up 3.45, and is trading even higher in the aftermarket on more than 5 million shares today.

Junior energy stocks ran as well. GEOI was up 2.81 on 2.8 million, a big percentage gain there, and ABLE up 2.28 to 11 1/2 on nearly 3 million shares as well.

Other stocks of note, CRYP went to a new multi-year high over 33 and closed right under it, up 1.21.

DCAI was up 1.85, and PACT, another Chart of the Week, was up 49 cents, or about 5 percent. ZICA snapped back with a vengeance, up 55 cents.

On the losing side, AIRT gave back 1.06. HLIT cracked 10, but snapped back above it, closing down 48 cents on the day.

ESLR and some of the energy stocks were flat to fractionally lower today.

Stepping back and reviewing the overall patterns, the market double-bottomed just above the 1500 level on the NDX, which was key support.

The S&P held the 1200 area, and that's very significant. We'll see if we can get an extension of the rally and a follow-through tomorrow.

Good trading!
