NEW YORK (TheStreet) -- An analyst upgraded Himax Technologies (HIMX - Get Report), helping its stock to rise.

Shares of the Taiwan company rose 9.7% to $8.52 after Chardan Capital Markets raised its rating to buy from sell. Guidance Software  (GUID) was on the rise after announcing enhancements to one of its core programs. There was also good news for Constant Contact (CTCT), which is coming off a disappointing last quarter. 

Chardan analysts were encouraged that Himax Technologies was supplying Microsoft (MSFT - Get Report) with its signature silicon liquid displays for the software maker's HoloLens augmented realty  headsets. Himax Technologies was already providing this component for Google (GOOG - Get Report) Glass, but it will provide more content for the Microsoft product. 

Microsoft is reportedly going to make the HoloLens available later this month as it looks to boost its presence in the consumer electronics space. Redmond, Wash.-based Microsoft sees other potential uses for the HoloLens, including for education and research. The company announced that it would award five $100,000 grants and 10 HoloLens development kits to design teams that present innovative uses of the HoloLens.  

Silicon liquid displays were originally developed for projection televisions but have become a core part of head-mounted displays. such as augmented realty products. 

Guidance Software shares increased more than 7% to $8.98 a share a day after it announced it would improve its Software Global Partner program to provide wider, global access to its cybersecurity solutions. The Pasadena, Calif., firm offers these products and services to corporations and government agencies for digital investigations. 

"We've always believed that a strong commitment to our channel benefits everyone, especially the customers who are looking for complete security solutions," said Jay Ackerman, chief revenue officer at Guidance Software, in the July 6 statement. "Protecting enterprise data from cyber and insider attacks is a growing challenge, so the more closely we can work with and support our channel partners, the more effectively we can deliver security technology and training that close a critical gap."

Constant Contact's price spiked 7.3% to $30 after the company said it would join the S&P 600 small-cap index. The company will replace West Pharmaceuticals (WST - Get Report) after the close of trading Wednesday. 

The Waltham, Mass. provider of digital marketing tools for small businesses reached a two-day high in trading Tuesday before falling back to finish at $30 a share. 

Shares of Constant Contact fell this spring to under $25 a share after it missed first-quarter earnings projections, lowered its guidance for the remainder of the year and was downgraded. But the stock price has rebounded slightly since the late spring. The stock was trading as high as $42.93 a share in March.
