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.

ATP Oil & Gas shed nearly half of its value last week. A Bloomberg report detailing bondholders gearing up for bankruptcy clearly didn't sit well with investors in the offshore oil exporter.

VirnetX slipped after a setback in its efforts to enforce patents related to the security standards for 4G and LTE devices. The U.S. International Trade Commission found a "procedural discrepancy" in VirnetX's complaint.

Zynga fell after falling short in its latest quarter. A sequential dip in bookings was enough to give credence to the bearish argument that the social gaming giant may be peaking. Zynga's guidance did little to crush the naysayer thesis.

RadioShack added insult to injury by suspending its dividend after an ugly quarterly report.

Finally we have Netflix also serving up gloomy guidance for the balance of 2012. The leading video service may have topped 30 million global subscribers, but a weak outlook for net additions during the current quarter leaves was unsettling.
