It was a rocky week on Wall Street, with Nasdaq stocks inching lower and the Dow inching higher, but there were plenty of stocks really making some serious moves. Let's take a closer look at five of this past week's biggest scorchers.

Let's start with China Digital TV, which soared after coming to terms with Cinda Investment on an asset restructuring. It will contribute a few of its businesses to a publicly traded entity controlled by Cinda. China Digital TV will receive cash and a majority stake in the entity. This was once a market darling as the leading provider of conditional access systems in China, at a time when the world's most populous nation was making the switch to digital. It hasn't been the slam dunk that investors were hoping for, and the stock's been trading in the single digits for five years. An asset restructuring will provide funds and focus for China Digital TV to set things right.

Southcross Energy Partners moved higher after its parent company struck a deal to combine with a privately held gas gathering and processing partnership located in the Eagle Ford shale region of South Texas. Stifel upgraded Southcross Energy Partners from "hold" to "buy" on the news.

Yelp generated a five-star review from Mr. Market as a sympathy play. When it was revealed that OpenTable will be acquired in a $2.6 billion deal -- a 46% premium to where the stock was previously trading -- speculators began loading up on Yelp under the assumption that it will be the next foodie darling to be acquired by either a tech giant or a travel portal. 

Shares of Applied Micro Circuits were served higher after Canaccord Genuity initiated coverage on the company with a bullish "buy" rating and a $16 price target. A pair of other analysts also reiterated their upbeat positions on the prospects of Applied's 64-bit ARM processors for enterprise servers.

Finally, Isis Pharmaceuticals inched up after scheduling an investor event to update the market on its progress. Isis is speaking at the American Diabetes Association's 74th Scientific Sessions tomorrow morning. Isis also got a boost from Jim Cramer, who talked about the company's promising pipeline on his CNBC Mad Money show.
