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: Shares of Coinstar (Nasdaq: CSTR) rose as much as 11% in intraday trading when the Redbox operator's first-quarter financial results and Q2 guidance easily beat estimates.

So what: Volume helped Coinstar overcome higher operating costs. Overall revenue surged 31% to $424.1 million. Sales from Redbox DVD rentals increased 38% and now account for 85.4% of revenue. Adjusted profit improved 53% to $0.46 a share. Wall Street had been calling for $409.4 million in revenue and $0.22 a share in adjusted earnings.

Now what: But if investors liked the Q1 results, they loved management's Q2 guidance. Executives expect Coinstar to take in $0.76 to $0.86 a share in adjusted profits on $430 million to $450 million in revenue. Analysts had been calling for $0.68 and $432.7 million, respectively, Yahoo! Finance reports.

Video games will play a role in producing those numbers. In June, Coinstar will begin renting popular titles via its Redbox kiosks, forcing Netflix (Nasdaq: NFLX) to find a way to respond. Well-played, sirs.
