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 household-products maker Blyth (NYSE: BTH) fell as much as 16.4% in very heavy market action, but it surely smelled good doing it.

So what: The maker of photo frames and scented candles just reported third-quarter results that fell short of analyst estimates. It then reaffirmed next-quarter earnings guidance but lowered the cash-flow targets. That's hardly a wholesome combination.

Now what: If the cash-flow warning weren't bad enough, Blyth also announced a change in its fiscal year, now equal to a calendar year rather than ending the last day of January. The company is in the midst of a long and difficult strategy change, now focusing on direct-to-consumer sales rather than wholesale operations. I'm not convinced that this is the right move, and neither are our CAPS investors -- Blyth owns a rock-bottom one-star rating out of five.
