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 home fragrance specialist Blyth (NYSE: BTH) surged 14% today after the company's quarterly results and full-year outlook impressed Wall Street.

So what: Blyth's fourth-quarter results were so strong -- normalized EPS of $3.74 versus just $2.74 in the year-ago period -- that analysts are being forced to raise their growth expectations yet again. In fact, the shares are busting through their 52-week high on the report and are now up a whopping 135% over the past year.   

Now what: Due to solid sales at its nutritional supplement subsidiary ViSalus, management now sees a 39% jump in full-year 2012 earnings. "We are planning for continued strong growth at ViSalus due to the strength of the products and programs that drove the momentum experienced in 2011 and their extensions in 2012," said Chairman and CEO Robert Goergen. Given the stock's recent tear and P/E of more than 50, however, much of that optimism might already be baked into the price.
