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 InvenSense (INVN) got crushed today, down by as much as 13%, after the company reported earnings and its CEO stepped down.

So what: Revenue in the second quarter came in at $55.3 million, which resulted in net income of $13.7 million, or $0.16 per share. Those figures narrowly missed the consensus estimates of $55.6 million in sales and a $0.17 per share profit. The results were near the midpoint of the company's guidance.

Now what: Founder Steven Nasiri is stepping down as CEO and chairman, although he will remain a director and serve as an executive through the end of the year to make for an easy transition. Nasiri founded InvenSense nearly a decade ago and held the CEO and chairman positions since then. Behrooz Abdi has been appointed as CEO, after serving as a director since last summer.
