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) surged more than 10% in early trading on news of a potential partnership with Verizon (NYSE: VZ) in Big Red's bid to compete with Netflix (Nasdaq: NFLX).

So what: Multiple reports now say that Verizon wants to offer a streaming service. Having Redbox as a partner could help Big Red go after not just Netflix but also Amazon.com (Nasdaq: AMZN) and DISH Network (Nasdaq: DISH), which also offer Netflix-like on-demand offerings.

Now what: It's too early to predict how well this pairing will play with consumers, but if history is a guide, today's rally is likely to be premature. Do you agree? Would you buy shares of Coinstar at current prices? Please weigh in using the comments box below.
