There's never a shortage of stocks going the wrong way in any given chunk of time. No stock goes straight up, and sometimes fundamentals can get a bit wobbly. Let's take a closer look at five of this past week's biggest sinkers.

Let's start with Coach. The maker of luxury handbags dropped its pocketbook after warning of continuing declines in revenue. Coach's uninspiring news didn't go over well on Wall Street. Morgan Stanley, Goldman Sachs, Barclays, Nomura, KeyCorp, and Stifel Nicolaus all slashed their price targets. William Blair and BMO lowered their ratings on the stock.

ConAgra investors were left hungry for more after the food giant behind Slim Jim beef jerky, Chef Boyardee canned pastas, and other iconic supermarket brands warned that it will come up short on the bottom line in its upcoming earnings report. ConAgra blames the weakness in its consumer foods and private label businesses for the shortfall. ConAgra now sees profitability clocking in closer to $0.55 a share, off from its earlier guidance calling for net income to come in just north of $0.60 a share.

Unfortunately for ConAgra shareholders, this isn't a fluke. This is the second time this year it has hosed down its earlier forecasts. The silver lining for potential investors is that the stock's 11% slide bumps its yield up to a notable 3.5%.

Shares of DreamWorks Animation lost some color after How to Train Your Dragon 2 got off to a bad start at the local multiplex. It rang up just $50 million in its opening weekend, short of the forecasts calling for as much as $60 million. The sequel to 2010's surprising blockbuster is faring well on the critical front. A whopping 92% of film critics tracked by RottenTomatoes.com liked the movie. However, it didn't prove to be the magnetic summertime smash that DreamWorks Animation was hoping for.

Hercules Offshore went from hero to zero after revealing that it had to forgo a contract that would have generated roughly $110,000 a day through late 2016 in Angola. Hercules Offshore failed to obtain the required approval of a local rep. 

Finally we have QIWI slipping after completing a secondary offering. It sold nearly 8 million shares at $40 apiece, but just a quarter of the sales sold were by QIWI itself. The balance of the American depositary shares came from existing investors, and that could show a lack of confidence. It's a shame, because the Russian provider of a fast-growing payment-enabling network has been on a roll, deploying 15.5 million virtual wallets and more than 167,000 kiosks and terminals. QIWI is processing transactions from more than 70 million consumers using its network at least once a month.
