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 specialty coffee company Green Mountain Coffee Roasters (Nasdaq: GMCR) perked up 20% on Wednesday after its quarterly results and full-year outlook easily topped Wall Street expectations.

So what: Fueled by a big 101% spike in second-quarter sales, Green Mountain posted an adjusted second-quarter profit of $0.48 per share, versus the average analyst estimate of just $0.38 per share. Demand for the company's Keurig one-cup brewing system continues to grow at breakneck speed, and with the shares hitting a new all-time high today, investors are doing all they can to keep up.

Now what: Reflecting that impressive momentum, Green Mountain also raised its current-quarter and full-year guidance well above analyst estimates. Keurig's ever-growing popularity, price increases on its K-Cups (which have largely offset rising coffee costs), and a recent licensing deal with coffee giant Starbucks (Nasdaq: SBUX) are all factors working heavily in the company's favor. While Green Mountain's valuation is just way too rich for my long-term tastes, all signs point to more whopping sales growth in upcoming quarters.
