This stock closed up 3.4% to $2.12 in Thursday. Thursday's Range: $1.97-$2.23 52-Week Range: $1.07-$5.19 Volume: 300,000 Three-Month Average Volume: 373,233 From a technical perspective, OPXA bounced higher here right off its 200-day moving average of $2.05 with lighter-than-average volume. This stock has been downtrending badly for the last month, with shares dropping from its high of $5.19 to its recent low of $1.28. During that move, shares of OPXA were mostly making lower highs and lower lows, which is bearish technical price action. That said, OPXA has started to rebound off that $1.28 low and quickly moving within range of triggering a near-term breakout trade. That trade will hit if OPXA manages to take out some near-term overhead resistance at $2.26 to $2.48 and then above $2.74 with high volume. Traders should now look for long-biased trades in OPXA as long as it's trending above its 50-day at $1.75 and then once it sustains a move or close above those breakout levels with volume that hits near or above 373,233 shares. If that breakout hits soon, then OPXA will set up to re-test or possibly take out its next major overhead resistance level at $3.25. Any high-volume move above $3.25 will then give OPXA a chance to trade north of $4.
