Universal Display has been in a steep up-channel for the last month, popping and flagging several times as it has risen from the $35 area to over $55.

3. Rudolph Technologies (RTEC) - Get Report

Rudolph Technologies broke out early last month and flagged, and then broke out again, and is currently pullng back in a bull wedge. It did gain 15 cents to $14.50 on 434,500 shares traded on Monday. If it does run through here, the maker of equipment to help chip manufacturers test for defects could see its shares reach the channel top near $18.00.

4. NeoPhotonics Corporation (NPTN) - Get Report

After breaking out of a wedge several weeks ago and pulling back to test support, NeoPhotonics appears to be popping again. The maker of components for communications networks gained 33 cents, or 3%, to $10.92 on Monday on 1.45 million shares. It reached $11.19 in June, and Monday's high was $11.15, so that's an area to watch. If it can get through there, it may explode, with the mid-channel target at around $14, and the top of the channel projecting to $19-$20.

5. NovoCure Limited (NVCR) - Get Report

After its IPO two months ago, NovoCure popped, pulled back and has coiled for the last six weeks. It looks like it broke out on Monday, up $2.34, or 9.4%, to $27.16, on 8 million shares, after the cancer-fighting biotech company was featured by Jim Cramer on Mad Money. It could very well get a new test of the high, with the target at $30-31 short term.
