Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Share of voice and video conferencing technologist Polycom (Nasdaq: PLCM) look sharp today, jumping as much as 15.9% on heavy trading action.

So what: Polycom's first quarter beat analyst targets on all points with non-GAAP earnings of $0.48 on $344 million in revenue. Business was better than the previous quarter, which runs athwart normal seasonal patterns.

Now what: You knew that video conferencing was big when Cisco Systems (Nasdaq: CSCO) started making huge bets on the scene. But Polycom has ridden the extra exposure to its sector that Cisco brought along like a rodeo cowboy on spring break in Cancun. Since Cisco announced the Tandberg deal, the networking giant's stock is down by 25%, but Polycom has more than doubled to a 125% return. If you saw that coming, you're probably a Rule Breaker at heart.
