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 direct-to-consumer marketing company Blyth (UNKNOWN:BTH.DL) dropped as much as 23% today after the company reported earnings.

So what: Revenue plunged 32% in the second quarter to $211.7 million and the company lost $3.2 million, or $0.20 per share. To make matters worse, management lowered full-year earnings guidance to $0.75 to $0.90 from a previous range of $1.30 to $1.45.  

Now what: The lowered full-year guidance tells you all you need to know about where Blyth's business is headed right now. The ViSalus business is really struggling and there doesn't appear to be a turnaround in sight. I'd stay away from this stock given the earnings trajectory right now.
