5 Stocks Moving On Friday's After-Hours: From Barracuda To TerraForm

Shares of Barracuda Networks Inc CUDA fell roughly 34 percent, responding to the announcement of lukewarm earnings and poor guidance on Tuesday afternoon. On Thursday, they recuperated 1.99 percent; on Friday, an extra 12.71 percent. Now, in after-hours trading, the stock continues to rise, more than 1 percent, as investors realize the selloff was somewhat overdone.

Multi-Fineline Electronix, Inc. MFLX seems to be the biggest gainer in the afternoon so far, up about 2.3 percent since the bell rang. No particular news seems to be driving the surge, which looks more like a continuation of the 1.65 percent rise the stock experienced during the regular trading session.

Breitburn Energy Partners LP BBEPP is also on the rise. The stock gained 6.95 percent during the day, and an extra 1.6 percent in after-hours trading on Friday, after the company announced a Thursday “a cash distribution of $0.04166 per common unit for the first month attributable to the third quarter of 2015, payable on October 16” (BusinessWire).

On the other hand, small-cap Esperion Therapeutics Inc ESPR is the biggest loser so far, down about 5.6 percent since the market closed. Once again, no particular news seem to have triggered the decline, which looks more like a correction of the 12.51 percent increase in the stock price seen during the day.

Similar is the case for TerraForm Power Inc TERP, which rose 12.66 percent during Friday trading, but is down more than 4.6 percent in after-hours, after Bloomberg published an article titled “Investors Are Asking Tough Questions About 'Yieldcos,'” which questions TerraForm’s collective funding arrangements with Sunedison Inc SUNE.
