What this transaction means for investors

This sale shouldn't concern investors. It represented a small percentage of the officer's holdings in the stock. It was also executed under a Rule 10b5-1 plan, which insiders commonly use to make sales for personal financial management reasons without regard to the company's fundamentals or valuation.

Importantly, the company's TTM revenue grew 10% year over year through the second quarter. Its operating margin is holding firm in the mid-teens range. This shows solid execution in the company's strategy to link providers and patients with testing and results.

Analysts anticipate around 8% annualized earnings growth over the next several years, with the stock currently trading at 20x this year's consensus earnings estimate.
