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 Align Technology (ALGN -1.04%) -- the company behind Invisalign braces, as well as other computer-aided design and manufacturing technology for the dental industry -- imploded today, falling as much as 28% after releasing its preliminary third-quarter results.

So what: The third quarter is historically a slower time of year for Align, but this goes far beyond that. The company announced that its preliminary third-quarter results point to an 8% increase in revenue to $136.5 million and $0.28 in EPS. Both results fell shy of Wall Street's expectations of $0.29 in EPS and $140.2 million in revenue. Align's fourth-quarter forecast also disappointed, falling short of the consensus figures. Align blamed the poor results and forecast on weaker sales in the North American market, and the termination of a distribution agreement for its iTero intra-oral scanners, which could result in a goodwill impairment charge either this quarter or next quarter.

Now what: Align Technology wasn't particularly cheap prior to today's tumble, and it's still not particularly attractive with a goodwill cloud overhanging its earnings forecast for the remainder of 2012. I will say that I do like the long-term prospects for dental companies as they have incredible margins for the products they create, but with consumer spending growth so weak right now, I could easily see some consumers postponing elective dental procedures, which could hurt Align even further. For now I'm happy just adding it to My Watchlist.
