Over the past few years, cloud computing has become a hot topic. A variety of companies -- like NetSuite (N) -- have built applications that are based on Internet technologies. The result is improved productivity and lower costs.

Yet, in order to continue to propel the cloud-computing revolution, there needs to be a strong technology foundation, such as with servers, operating systems and application development tools. And one of the top players in the market is Red Hat (RHT).

Red Hat (RHT), an open-source software business whose colleagues include Microsoft (MSFT) and Oracle (ORCL), experienced some selling pressure in yesterday's extended-hours session.

And if you look at the chart, you'll see that the shares have been in an uptrend following a period of sideways movement. Should an investor buy this uptrend? Is yesterday's selling action a temporary phenomenon?

Red Hat (RHT) is doing extremely well today. At the time of this writing, shares of the software entity were up nearly 12% to $41.15. Volume was great. The catalyst for all this action is the earnings report that was released yesterday after the bell.

Earlier today, the stock hit a new 52-week high of $41.48. The 52-week low for the shares is $24.78. This is a very impressive move. Looking at the one-year chart, we see that the company has broken out of a period of sideways action. Technically, the short-term players have got to pay attention to the thesis.
