If you're bullish on FINL, then I would wait until after its report and look for long-biased trades if this stock manages to break out above some near-term overhead resistance levels at $21.63 to $22.26 a share with high volume. Look for volume on that move that hits near or above its three-month average action of 586,106 shares. If we get that breakout, then FINL will set up to re-test or possibly take out its next major overhead resistance levels at $24.65 to $25.76 a share. Any high-volume move above those levels will give FINL a chance to tag $30 a share.
