1. Celator Pharmaceuticals (CPXX) , one of our swing trade picks, is doing very well. It gained another 65 cents, or 5.2%, to $13.08 on volume of 3.4 million shares Wednesday. The stock exploded in mid-March on news of breakthrough trial results for treating acute myeloid leukemia, moving from $1.68 to nearly $9 in just one day. The stock pulled back for two days, popped, pulled back for three days, and now it's moving again. The top of the channel says this stock could reach $17 or $18 in the near term.

2. FireEye (FEYE) - Get Report , after dropping from the high $50s in mid-2015 to the low teens in February, has since reversed about 50%. The cybersecurity company's stock gained 75 cents, or 4.3%, to $18.21 on Wednesday as it threatens to break out of its recent coil, where it resides above the moving averages. The first target is the recent high near $19.50, and the secondary target is the January high near $22.50.

4. LSB Industries (LXU) - Get Report broke out in early March, wedged, and broke out again a few weeks ago, forming another wedge. The chart pattern of the chemical maker is bullish, and a break above the $13 level could trigger an initial move to recent highs at around $14.
