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 Harmonic (Nasdaq: HLIT) jumped 10% briefly this morning after the company reported earnings.

So what: During the second quarter the company said that revenue rose 3.8% to $132.6 million and net income was $17,000, or break-even per share. On an adjusted basis the company reported earnings per share of $0.06, which was a penny below expectations.

Now what: The reported quarterly earnings didn't surprise on the upside but third-quarter guidance was in line with estimates and the company's cash flow is improving. Operational cash flow was $28.2 million in the quarter, up from $9.1 million a year ago, and shows the company's ability to turn revenue into cash. The company also has $177.8 million of cash, a respectable amount considering the company's $469 million market cap.

Earnings may have been slightly lower than analysts expected, but today I think investors are looking past that to next quarter and the company's increased bookings and cash levels. Investors knew that Europe would be a drag on this quarter, so some reassurance of confidence in future quarters made them feel warm and squishy today.
