Earnings reports for the second quarter dominated tech news this week, with companies like Intel, Microsoft, and Google holding investor calls and issuing detailed spreadsheets on what went right — and wrong — over the past three months.

Needless to say, the news affected investors’ confidence. When the Google reports disappointed expectations, stock prices dipped accordingly.

Let’s take a look at stock prices for companies who reported Q2 results this week:

Hardware/mobile companies

Five companies involved in hardware had their earnings calls this week.

The takeaway: You probably already know this, but mobile devices are where it’s at. And while Windows Phone is slowly picking up steam, it’s not yet a contender, especially in the smartphone-saturated U.S.

Here’s a look at the stock movement this week for these companies, shown as percentage change:

Software companies

We also had four software companies reporting revenues this week. (We were busy bees over here, y’all.)

  • Microsoft’s Q4 earnings disappointed, particularly the $900 million loss the company took for its written-off Surface RT tablets.
  • Google missed analysts’ expectations. While revenues were significantly up, profitability was slightly down.
  • In eBay’s quarterly call, the shining star was PayPal, which showed no signs of weakness amid the onslaught of startups like Stripe and Square.
  • Yahoo’s earnings were still strong but showed a slight year-over-year decline.

Dotcom’s oldsters were still mixed, but we’re seeing Yahoo as a front runner for the Comeback Kid title — and investors apparently feel the same way. Overall, under CEO Marissa Mayer’s leadership, Yahoo has had one of its best years yet and more acquisitions and gorgeous product roll-outs than you can shake a stick at.
