From a technical perspective, ARAY is bouncing sharply here off some near-term support at $5.90 with light volume. This move is quickly pushing ARAY within range of triggering a major breakout trade. That trade will hit once ARAY takes out some near-term overheard resistance at $6.6, and then its 50-day at $6.69 with high volume.

Traders should now look for long-biased trades if ARAY can sustain a move or close above those levels with volume that’s near or above 611,373 shares. If we get that action soon, then look for ARAY to tag its next major overhead resistance levels at $7.30 to $8.07. That $8.07 level can be achieved once $7.30 is taken out with volume. Traders should look for those near-term support levels at $5.90 to $5.80 to hold up if this stock is going to make that run soon.

Traders should look for long-biased trades if LDK can sustain a move or close above those levels with volume that’s near or above 16 million shares.
