There's never a shortage of losers in the stock market.

Let's take a closer look at five of this past week's biggest sinkers.

Dycom posted disappointing financial results. The provider of engineering, construction, and other industrial services to the telecom, cable, and utility industries saw its contract revenue and profitability grow at slower clips than analysts were expecting.

Frontline sank after revealing that it will not pay a dividend for the quarter after posting a larger loss than Wall Street was forecasting. Even after backing out meaty vessel impairment charges, Frontline still would've come up short.

First Solar saw its stock set like the sun after reports that the solar energy bellwether was halting deliveries to a $1.8 billion solar power plant project in Arizona.

It was a week of brain drain at Zynga. The company's Chief Creative Officer left the company earlier in the week, and then Bloomberg reported on Thursday that two more key executives were leaving the social gaming giant.

Finally, we have Vringo shares shrinking. The patent-rich company behind a popular app that generates video ringtones saw its stock take a hit, even after issuing an update on where its patent litigation is at these days.
