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 Infoblox. The provider of automated network control solutions lost more than a third of its value after offering up gloomy guidance and the resignation of its longtime CEO. Its latest quarter wasn't so hot with revenue increasing 5% and adjusted profitability tanking 26%, but that was in line with Infoblox's earlier top-line guidance and ahead of Wall Street's profit projections.

Things got ugly with its guidance calling for $60 to $61 million in revenue -- a sequential downtick -- and no more than $0.02 a share in earnings. Analysts were forecasting a profit of $0.05 a share on $66.6 million in revenue. Adding to the uncertainty, Robert Thomas -- Infoblox's president and CEO of nearly 10 years -- announced that he was leaving the company.

The other shoe dropped at DSW after the footwear retailer posted abysmal quarterly results, hosing down its guidance for the entire year. DSW blamed the weather in part for its woes, but that doesn't hold up. After all, its new outlook assumes lower profitability for the balance of the year than it was originally projecting. Does it have a psychic meteorologist on staff? Susquehanna Financial downgraded the stock after the report. 

Another retailer to slip in its latest report was Pacific Sunwear. The once trendy retailer offered up disappointing guidance for its current quarter. That's a pretty big deal since the current quarter is a seasonally potent one for the beachwear and outdoor apparel mall chain. If it can't turn a quarterly profit now -- the way it did a year earlier -- it's going to be a long road back for PacSun. DA Davidson lowers it price target on the shares from $5.50 to $4 on the news.

UQM slumped after an uninspiring quarterly report. Its deficit may have narrowed, but revenue slipped despite landing a pair of new international customers. UQM's performance was held back by a delayed start for the 2014 California Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project. 

Finally we have Lions Gate Entertainment failing to roar in its latest quarter. Lions Gate had fewer box-office releases, but analysts knew that and the studio still fell short of low expectations. Divergent was a smash, but its other releases this year -- Draft Day, The Legend of Hercules, and I, Frankenstein -- failed to woo patrons at the local multiplex.
