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 Invisalign maker Align Technology (Nasdaq: ALGN) had investors showing their pearly whites today by jumping 19% after the company released earnings.

So what: Revenue hit $104.9 million, topping estimates of $100.6 million, and earnings per share of $0.21 beat estimates by $0.04. The company now expects revenue of $106.5 million to $110.5 million in the second quarter and earnings per share between $0.19 and $0.21 -- both above analyst estimates.

Now what: The company cited higher traffic in orthodontic offices in North America and better execution for the better results. The bottom line is that customers who can afford to go with high-value products like Invisalign are choosing the product more frequently. This bodes well for the company's future, but I would like to see shares come off their highs before jumping in today.
